Ball Valve Troubleshooting
Our 2 piece and 3 piece ball valves are considered full port valves meaning they whatever size ( i.e. 1’’ 2’’ all the way through. , it has an over-size ball so that the hole
in the balls is the same size as the pipeline resulting in lower friction
loss. The flow would be unrestricted but the valve is larger so this works
out great when free flow is required
A good resource as well is the valves pdf that can be found on the server
Server > Shared Files > Work Files > Valves PDF
It’s a best practice for us to email the customer this diagram to help them understand how each ball valve will work.
The terms WOG 200 AND WOG 1000 are referring to the nominal working pressure of the ball valve.
Check Valve Troubleshooting
Check valves are used to help direct flow in one direction. The stainless steel bodies and PTFE seals are highly corrosion resistant allowing these check valves to be used with a wide variety of fluids including, but not limited to water, oil, gas, air, light alkali's, acids, biodiesel, fuels and alcohols.
Swing check valves are for horizontal use only. When fluid pushes on the stopper in the correct direction, it will "swing" open to allow flow. If flow moves in the opposite direction, it will swing shut. The check valve cannot be used in vertical applications as gravity may affect the function of the swinging motion.
Vertical check valves may be used for any application. They utilize a spring system which shuts the Disc closed when there is not enough pressure to hold it open by the operating fluid. Fluid pressure in the backwards direction will cause the valve to close to prevent backflow.
Note: Check valves do not create a 100% seal against backflow like a ball valve would. If prevention of backflow is desired, two check valves should be used in series with each other. Any fluid which finds its way past the first check valve is unlikely to have enough pressure to pass through the 2nd.
Both check valves are 2-piece and serviceable. They may be opened by unthreading at one of the port ends.

Acetic Acid - Glacial Acetic Acid, also known as ethanoic acid is an organic compound with the chemical formula of CH3COOH. It is the main component of vinegar, which is typically made between 5% and 10% concentration mixed with water. It has a distinctive sour taste and pungent smell. Acetic acid is used widely for descaling, as a chemical reagent and as a food additive. In household uses, it is an excellent weed killer and for use in foods and cooking.
Glacial acetic acid Freezes at 62°F. In lower concentrations with water, the freezing point lowers to below the freezing point of water. As the solution becomes more heavily concentrated with water, it will freeze close to 32°F.
99.85+% Concentration, Freezes at 62°F
Acetic Acid can’t be returned to use because it’s considered a corrosive liquid by the USDOT.
Acetone –Acetone (systematically named propanone) is the organic compound with the formula (CH3)2CO. It is a colorless, mobile, flammable liquid, and is the simplest ketone.
Acetone is miscible with water and is used as a very important solvent in many industries. Some examples are removal of paint, nail polish, laboratory cleaning, removal of glues and other adhesives, stains or dirt.
Acetic acid can’t be returned to us because it’s considered a flammable liquid.
Biobor - Kills Bacteria/Fungi in Tanks that container Diesel, Home Heating Oil, Biodiesel, Gasoline
Breaks up and prevents sludge, slime, clogged filters, bacteria corrosion and adds lubricity to lower sulfur fuel

Biobor can’t be returned to us because it’s considered a flammable liquid.
Boric Acid - Boric acid is non-toxic to mamals if consumed in small quantities. In small amounts, it should pass through your system without harm. If using as a pest control in a home where animals are present, we recommend making bait and putting it into a place where your pets cannot eat the material. Powder can be used for pest control with pets in the home if it is used in places where the animals will not get it on their feet/bodies. Animals which lick themselves / consume too much boric acid will possibly experience gastrointestinal symptoms.
To use boric acid in pest control, the idea is to get the pest to eat it, and their bodies will dry out, thus killing the bug.
Cockroaches / Dry Application
Cockroaches clean themselves every few seconds. Boric acid powder can be lightly placed on surfaces where cockroaches are found. They will run over the boric acid powder, clean their feet, and then die from consuming the boric acid on their feet. Do not apply too much as bugs can detect the boric acid and may avoid it. Granular boric acid does not work well for this application. It must be powder. Baits can also be made (see ants)
Ants / Bait Method
an ant problem is no problem for boric acid. Mix the granular or powder boric acid with sugar, roughly at a 5% or less boric acid concentration. Too much boric acid can repel the insects. In the case of ants specifically, higher concentrations may be used. Next, add small amounts of water to make it into the texture of a paste. Apply the paste around areas of where ants / pests are found. They will eat the bait and then die. Ants will carry the bait back to the colony and the entire colony will die. In most instances, ant colonies can be wiped out in a matter of hours.
Other pests
other bugs which clean themselves regularly, are not in the larva stage and do not have piercing mouthparts may be eliminated using boric acid. Boric acid will not kill bed bugs or bugs which feed on blood or plant juices.
Bromophenol Blue - Bromophenol Blue is used as an indicator when titrating for soap. The ph range is from 3.0 to 4.6. 3.0 and under will turn yellow. 4.6 and above will be a dark blue.
Calcium Ascorbate -
What is Calcium Ascorbate?
Calcium ascorbate is one of the mineral sales of ascorbic acid (Vitamin C). It is alkaline. Ascorbic acid is acidic and may cause stomach issues related to acid reflux. Since Calcium ascorbate is alkaline, it is much less likely to cause such issues. Calcium ascorbate taken as a supplement will supply your body with both vitamin C (ascorbic acid) and Calcium.
What is Ascorbic Acid?
Ascorbic acid is another name for Vitamin C. Vitamin C is important to the body's diet. It helps in healing and fighting off disease and infections. But it is also helpful in processing carbohydrates, proteins and fats. It helps the body generate blood vessels, collagen, muscle and cartilage.
Vitamin C is found naturally in fruits and vegetables. Sometimes a person's diet may not contain enough Vitamin C and could need Vitamin C supplements. It may be useful when traveling in places where fresh fruits and vegetables are not readily available.
Applications
Vitamin C powder can be consumed by mixing it with water. Be sure not to use high concentrations as it has a very sour taste. Some may prefer to sprinkle it over food or put tiny amounts on the tongue, followed by a glass of water. The powder is an effective form for people who cannot swallow pills.
Vitamin C may also be used to prevent oxidation. As an example in its use, it can be sprinkled onto fruits prior to freezing them to prevent the fruits from browning (a sign of oxidation).
Dosages
It is recommended that men over the age of 18 consume 90mg of Vitamin C per day while for women over the age of 18 should consume 75mg per day. While slightly larger amounts of Vitamin C may not be harmful, usually consuming more than the needed Vitamin C will simply pass through the body without adequate processing. If very large amounts are consumed (over 2000mg) then it can actually harm the body.
How much is in a teaspoon?
This is a very common question. However, knowing how much is in a teaspoon is not very useful for measuring a daily dosage since a teaspoon contains over a month worth of nutritional value. A teaspoon amount is only useful for cooking recipes or when dividing the ascorbic acid into the volume of something bigger to be consumed over time (a container of water that can be measured again into smaller quantities). For direct daily intake, a pocket scale should be utilized for measuring out the milligrams (1000mg = 1g). In case you need to know how much is in a teaspoon, see the "density" paragraph below.
Density
The density of the 80 mesh ascorbic acid powder varies between 0.9-1.2 g/ml. There is about 5 ml in 1 US teaspoon. So there is a range of 4.5g-6g, or 4500-6000mg of ascorbic acid per teaspoon. If you are an adult male that needs 75mg of ascorbic acid, a teaspoon results in at least 6000% of your daily needed intake. To take the proper amount, you would need to consume no more than 1.67% of a teaspoon. This is impossible to measure and so we recommend to either mix this teaspoon into something else and divide that food up appropriately or to use a pocket scale with 0.01g reading accuracy to measure it out.
Calcium Carbonate – Some of the many common uses for calcium carbonate are as follows: Dietary supplement for calcium, common antacid, filler material for a wide variety of products (toothpaste, paper, paints etc.) and blackboard chalk.
Citric Acid – Our citric acid is non-gmo organic and may be used in organic foods. Some highlights and specs of citric acid are as follows:
· Food grade
· Pure Citric Acid - Anhydrous (No Water or other additives)
· highly refined. Extremely pure. Does not contain detectable amounts of protein strains from the original feedstock.
· FCC/USP (For use in Recipient/Food, not for use in drugs)
· Use for water softening, craft making, candy making, pH adjustment of shampoo bases & more!
· Bath Bombs: Combine with sodium bicarbonate to make fizzy bombs for your bath.
· in candy making, citric acid provides a sour flavor. This is what's on War heads.
· Using citric acid, cleansers become lather and will clean better due to the softened water.
· Pool care Make a paste and remove stains from your swimming pool liner and fiberglass pools (TEST FIRST!)
· For Soaps: Chelate metals in hard water.
· TILE CLEANER- Prepare 1 cup of Citric Acid with 3 cups of water in a bowl. Stir until completely dissolved. Apply to tile with a scrub brush. Rinse clean. Dirty, stained Tile will once again be beautiful and shiny bright!

Formic Acid - 95% Concentration, 5% water
Formic acid is an important intermediate in chemical synthesis and occurs naturally, most notably in ant venom. Its name comes from the Latin word for ant, formica, referring to its early isolation by the distillation of ant bodies. Esters, salts and the anions derived from formic acid are referred to as formates.
Formic acid is a colorless liquid having a very pungent penetrating odor at room temperature. It is miscible with water and is of the most polar organic solvents and is somewhat soluble in hydrocarbons.
A major use of formic acid is as a preservative and antibacterial agent in livestock feed. It is used in Europe with silage (and fresh hay) to promote the fermentation of lactic acid and to suppress the formation of butyric acid.
Formic acid is also significantly used in the production of leather, including tanning and dyeing and finishing of textile because of its acidic nature.
Formic acid is also used in place of minerals acids for various cleaning products, such as lime scale remover and toilet bowl cleaner. Beekeepers use formic acid as a miticide against the tracheal mite and the varroa mite.

Glycerine / Vegetable Glycerine
USP / Food Grade
High Quality - The Best in the Market
99.7+% Concentration
Our vegetable glycerin is of the highest quality and rated as USP / Food Grade. It is a clear, viscous liquid with a density of 10.5 lb per gallon. This product is used in a wide range of applications such as soaps, food, pharmaceutical, personal care, science, antifreeze, chemical processing and fuel.
Our glycerine is distilled from Soy products and is a minimum specification of 99.7% purity. The 0.3% remainder is usually water as glycerine readily absorbs moisture from the air and is difficult to completely remove during the distillation process. There is no residue of the original feedstock in the glycerine for those who are concerned about possible allergens.
Made in the USA.
What is the difference between Glycerine and Vegetable Glycerine?
There is no difference between the two types of glycerine if they are pure and do not container any of the original feedstock. Glycerine has a chemical formula of C3H8O3 and regardless of where it comes from, it is exactly the same in every way. The only difference between the two is that traditionally glycerine comes from animal fats and vegetable glycerine comes from plants. The chemical is exactly the same regardless of what it is derived from, which is why we use the word Glycerine and Vegetable Glycerine interchangably on our labeling and descriptions. Our glycerine is derived from Soy and so it is considered vegetable glycerine, or glycerine of vegetables.
Hydrochloric Acid – 32 % concentration
Hydrochloric acid is a clear, colorless, highly pungent solution of hydrogen chloride in water. It is often and commonly used in concrete cleaning. It is also often used for pickling of steel, where rust / iron oxide is removed prior to further processing.

Phenolphthalein - 1% Phenolphthalein by weight in 200 Proof Denatured Ethanol
Phenolphthalein is an indicator used in titration of WVO. Add a couple of drops to your titration test. The solution will begin to turn a light pink as you add the lye solution. The goal is to find a ph of about 8.5, which is when the mixing solution stays light pink for about 30 seconds.
Phenolphthalein can be used for many other types of titrations such as soap titrations for soap making and biodiesel soap tests. It will work as an indicator for any application where the pH range is desired.
pH range: 8.0-9.8 (light pink to dark magenta)
Phenolphthalein will turn a very dark magenta / purple color if it is in the presence of a very high alkaline solution. Over time it will return to clear on its own.
The expiration date of phenolphthalein is indefinite if it is stored properly in a cool and dry place.

Phosphoric Acid – 85 % Concentration, Food Grade, Safe HDPE Bottle Child Satey Cap
Chemical Formula: H3PO4 Density: 98g/ml
Phosphoric acid is often used to acidify foods and beverages such as carious colas. It provides a tangy and sour taste.
We use Phosphoric acid to treat the by-product of biodiesel. after methanol extraction, using phosphoric acid allows a clean separation of the glycerin and soaps. If done correctly, it can yield 90% pure glycerin.
May also be used as a rust remover/inhibitor. Dilute to a 25-50% concentration with water and soak rusted metal parts. Over time, rust will remove and the phosphoric acid reacts with the metal to create a rust inhibiting barrier on the metal. Be sure to use gloves! Great for cleaning residue from metals.

Propylene Glycol – Food Grade / USP
by Duda Energy
Propylene glycol is a viscous, oily fluid which is commonly used in many products. Food grade propylene is safe for drinking and is non-toxic. It is often used as a food preservative, a non-toxic antifreeze, a humectant (to keep foods moist), solvent (ink jet printer cleaning), and in food refrigerant applications, such as in making icecream.
For antifreeze applications, we recommend using no more than a 60% by weight solution in distilled water. Water has a high specific heat capacity, so only the appropriate percentage should be use to prevent freezing and boiling. Excessive use of propylene glycol will cause the antifreeze to lose its ability to retain sudden increases in heat and often cause system failure, especially in vehicles. (This is the same rule for ethylene glycol as all) Use the following table as a guide for your antifreeze application.

Sodium Bicarbonate –
Does Baking Soda contain aluminum?
This is Ben’s favorite question, seriously, ask him sometime J Baking Soda has never and will never contain aluminum. Below is a generic standard response that I’ve made.
Hope you’re having a good day. Thanks to dubious marketing ploys by companies such as Bob’s Red Mill a lot of consumers believe baking soda contains aluminum, however it doesn’t. It’s the myth that just won’t die. People to this day confuse baking soda with baking powder and the presence of aluminum. Baking soda has never had aluminum; it was just a marketing ploy to help drive sales for other companies.
We chose not to feed into the paranoia so that’s why we don’t advertise ours as “Aluminum Free”. I hope this helps and I’m sorry for the confusion, if you want to take the time there is a pretty good article based on that hoax by crunchy betty. If you google “Does Baking Soda contain Aluminum” it’s the first link you will see. I would link it however Amazon filters outside links pretty heavily J

Sulfuric Acid – Sulfuric acid can be used a tree killer / cutter. Sulfuric acid compounds will attack the wood structures and will generally convert wood into carbon quite readily. However I would use a concentrated sodium hydroxide (lye) as it’s generally safer to work with than concentrated oxidizing acids (e.g. sulfuric or nitric acids). That said, it’s still nasty stuff, and you want to wear eye and skin protection when handling it. Please note that because wood readily absorbs water, it’s difficult to control the process and limit the dissolution to just one portion of the piece of wood; it’s more of an all – or nothing thing.
Sodium Nitrite – Sodium Nitrite is toxic and food grade at the same time. Ben used an example of table salt, if you ate 3 pounds of table salt at a time it will kill you. Sodium Nitrite is more potent than table salt so you would need to heavily dilute it down. Usually people that use sodium nitrite are preserving 10,000 lbs. or more at a time.
Sodium Nitrite shouldn’t be used for small quantities for preservation for small meat accounts
You can return it, however you would have to have the original box (for the diamond markings), since it’s an oxidizer you can’t ship it postal or air, has to go through Fed Ex ground and UPS ground.
Potassium Hydroxide – Can be used to neutralize acidic water, but we don’t have any way of calculating how much ne needs and it will likely release hydrogen gas, so they would need to be careful. Potassium Hydroxide (KOH) is very soluble in water as well.
Sulphur Powder – Unfortunately sulfur powder can’t be shipped internationally due to shipping regulations. The best we can do is ship it to you at the border and then you can walk it over. Unfortunately I don’t know of any sulfur powder dealers in Canada. We’re sorry for the inconvenience.

ISO is a standardized version, meaning they have the exact same thread count, the same thickness for the hex part, so if you buy a hex nipple from us and then buy one from a guy in San Francisco they will be the exact same.

Filter media sheets are designed for liquid filtering and should not be used as a pre filter for air applications.
Heat Exchanger Troubleshooting
Cleaning - A hops bag or spider is the number 1 thing. There should never be a reason for anyone to have a clogged heat exchanger - it only ever happens from people not using any sort of filter or screen and letting chucks of hops go straight into the unit.
I've heard of some good results with whirl pooling as well, but I'm not convinced that is as reliable as a screen without several runs to tweak it to working perfectly.
As far as cleaning, back flushing with boiling water and then using starsans before a brewing day to sanitize are our preferred methods. There are of course many other methods, but the rest seem to have both pros and cons:
PBW - I love PBW. Does a great job cleaning, but doesn't sanitize like starsans will. This is a good option if your filter didn't do a good enough job, or if you don't want to flush with boiling water.
Starsans after a day, rather than before for sanitizing - no point in this. Starsans won't clean as well as PBW will, and the risk you run into is some people like to let the exchanger just soak in starsans. Seeing as starsans is mildly acidic, this isn’t good for the long term life of the exchanger.
Lye solution - this is actually the method I prefer, submerging the exchanger in water and lye, but it is technically not recommended. The lye water will clean and sanitize better than any other chemical out there, but it can do some very minor damage to the chromium coating on the stainless steel, taking away a layer of its protection from corrosion. So you might have to replace the exchanger after 20 years if you go this route. This is also a much more dangerous chemical than the others mentioned; you want proper hazmat gear for this method. But it’s still the way I go, because the cleaning is second to none.
Baking - throw the unit in the oven, 400 degrees for 3 hours. This is my boss's preferred technique. No chemicals involved, absolutely sanitizes, burns out anything caught inside, and removes any fluids from inside the unit. My objection to this method is that some types of trub, if already inside, can get cooked into the unit and make things worse.
Orientation - It depends on how high your flow rates are to whether it needs to be mounted vertically or horizontally. If you have slower flow rates (anything less than 3 gallons per minute) then it’s recommended to mount them vertically due to the gravity effects that help prevent against pooling. Anything higher than 3 gallons per minute can be mounted however you like.
Input / Output - Yes, you are correct. The 1/2'' input and output would be for the wort. The 3/4 would be the water inputs and outputs for cooling the beer. You always want the bigger size to be what you want to achieve (either cooling or heating fluid etc.).
Your inputs should always be diagonal from each other as well. For Example, F1 goes to F4 and F2 goes to F3. Here’s a diagram that will illustrate how a heat exchanger works.

Fittings- Anytime a customer asks if a heat exchanger can have solder connections they are referring to copper sweat fittings. For Example, please see the below scenario.
“Example: Ben, HX1240 they are NPT's no solder connections?
Answer: copper sweat = solder connections,
So we have two options for the 1240
3/8" copper sweat
Or 3/8" Copper Sweat x 3/4" Female NPT”
Tidbits:
Our heat exchangers are based on a single pass design, not a multi-pass one.
Pumps
Basic Troubleshooting Questions
What is the working fluid you are using, what is your head, lift etc.? Does it run when it's dry? Or is it fully clogged?
Troubleshooting Steps
1) Something is stuck inside, try flushing boiling water through it (you may have already if so please disregard)
2) There could be that there is a vane damaged inside the pump, open up the motor head to see if that is the case.
3) Could be a damaged fan (if you plugged it in for the first time and this was the sound you got that is the most likely culprit)
Solenoid Valve Troubleshooting
Troubleshooting Questions –
I'm sorry to hear about the solenoid valve, if you don't mind me asking what the working fluid that you are utilizing is. It could be that something is stuck in the diaphragm and preventing it from making a complete seal, thus preventing a successful closure of the valve. In the event of clogging, these valves are easy to clean. Simply remove the 4 bolts holding the body together to access the diaphragm for cleaning, I would recommend running boil hot water through it as well. It would either be the diaphragm or a bad coil that is causing this issue. Let me know if cleaning the diaphragm works, if it doesn't then we will replace it for you.
Example: I was wondering if it was possible to swap the 24V DC coil on my DFD-25JV with a 24V AC coil. The solenoid unit I received hasn't been used yet, I just want to swap the coils. I will happily purchase a 24V AC and send this DC one back if that works for you.
Answer: It can work however you won’t get the full pressure rating due to the springs being designed to go with the weaker amperage. The only thing you would have to do is unscrew the hex nut and washer on the top of the coil, change out the coils, the screw back the nuts. You can purchase the coil from the link below, once you access the link you would then select 24v AC from the drop down menu. I hope this helps and take it easy!

Example: Hi, My valves are getting really hot after having been on for 15 minutes. Is there a good way to keep them cool?
Answer: It's normal for them to get hot, really the only thing you can do is to make sure the operating voltage should not be more than 10 % higher than the coil voltage rating. The excessive voltage increases the coil current which overheats the coil. Hope this helps
Example: I have purchased your Solenoid Valve [2W25025KN] which has a DIN connector.
Can you tell me the model of DIN connector that I need to connect to your valve?
Answer: They would be a 43 650 Style A model (IP 65 would be another spec on the din connector if that helps).
