1. Is the tank I purchased approved for drinking water?
The resin used to manufacture our linear polyethylene tanks (HDLPE) meet specifications contained in FDA Regulations 21 CFR 177.1520, © 3.2 and so may be used as an article or component of articles intended for use in contact with food, subject to any limitations in the regulation. Cross-linked polyethylene (XLPE) tanks do not meet FDA regulations. The HDLPE resin that Snyder uses is also NSF 61 listed.

2. How do I know what specific gravity tank will meet my needs?
A tank with a specific gravity of 1.5 can hold a liquid up to 12.5 pounds per gallon at 100 degrees F. A tank with a specific gravity of 1.9 can hold a liquid up to 15.75 pounds per gallon at 100 degrees F. Please note that an increase in liquid temperature will substantially decrease the specific gravity rating. Also, certain chemicals have environmental stress cracking agents in them so higher specific gravity tanks are needed to compensate even though the weight of the chemical may be lower. Please call Snyder Industries to determine which tank design is best suited for the chemical application.

3. What is the best way to install my discharge pump?
Snyder Industries recommends that you use a flex coupling or hose between the tank and the pump. Please ensure that the flex coupling or hose has a sufficient movement capability. Straight-line hose placement will not allow sufficient movement. This will provide more flexibility in the fitting area as the tank expands and contracts during filling and emptying. This will prolong the life of your purchase with this easy to install connection.

4. What is the recommended tightness of the hoops on my super nurse tank?
The hoops should be tightened to the point of full tank contact, but not to the point of causing tank distortion. The holes used to mount the hoop should positioned close to the tank to allow full contact at the bottom of the leg and hoop contact point.

5. Who do I contact for replacement parts (i.e. caps and fittings)?
Contact your local Snyder distributor listed on this web site. They carry a complete line of replacement parts to meet your needs.

6. What is the expected life of my tank? What is Snyder's Warranty?
There are many variables that can have an effect on the life of a polyethylene tank.

The type of material being stored in the tank, it's concentration, and temperature. 
The temperature of the application can be a factor, especially if the tank design is not based upon the temperature of the application. Some applications may permeate the polyethylene at elevated temperatures. Special considerations - some chemicals will have long term affects on the polyethylene and may require special considerations.

Installation and PIPING! - The number one reason for tank failures is due to improper installation. It is important to follow Snyder's guidelines for use & installation. Having flexible connections that compensate for the expansion and contraction of the tank will extend the life of the tank. 

All Snyder Ag tanks carry a full 3 year warranty on material and workmanship.

7. How often should I test my tank for cracks and wear and tear?
A visual inspection of your tank should be made each time you fill it. This is to ensure that there are no obvious outside defects since the last time the tank was in service. Snyder Industries provides a test kit for the inside of the tank to check for stress cracking. This test should be performed yearly to insure there is not any chemical attack of your Snyder tank.

8. Will Sulfuric Acid or another chemical work in my Snyder Ag tank?
Poly tanks have a broad range of chemical resistance to both Agricultural and Industrial chemicals. For Industrial Chemicals refer to the Snyder Chemical Resistance Recommendation Chart on that site or contact the chemical supplier to see if their product is compatible with high density linear polyethylene (HDLPE) or cross-linked polyethylene (XLPE). If they cannot answer your question, call Snyder Industries and we will be happy to research it for you. Try to have as much information available as possible such as the temperature of the product, the percent concentration of product (Ex: Sodium Hypo chlorite, 15%) etc.
