The tanks are made from polyethylene plastic. The tanks are food grade, non BPA plastic tanks. Made in Bellingham, WA USA.
We do not offer “plumbing kits” at this time.
Our water ports on the tank have female NPT threads, so you’ll need male NPT fittings. These fittings are widely available at hardware stores like Lowe’s, Home Depot, and Amazon. Boat supply stores also typically carry a good selection. Nylon fittings are the best choice for optimal performance. You may try looking for MNPT (male national pipe thread) that will screw into the tank ports.
The ports are 1.5″ NPT (National pipe thread). The measurement comes from the inner dimension of the pipe diameter. The external threads will measure larger than the internal pipe size.
Pipe size is measured by the inside diameter (ID) and the hole saw is measured with the outside diameter (OD). By measuring the port size a 1 3/4″ hole saw will fit just inside the threads and not damage any threads.
For fittings, brass will work but we have found that the nylon fittings seem to seat better. The brass and PVC type fittings seem to be a bit sharper and more fine thus making it easy to cross thread. All NPT fittings will work along with thread sealant of some sort (teflon tape) but the nylon seem to be best in our experience.
You can typically gravity feed into the water tank and the pump. If the tank is plumbed this way, it must be vented, usually as a vent overflow.
The tanks need to be vented. The upper end corners or top port are the normal venting locations. Filling the tank slowly will help as well to reduce the chance of pressurizing the tank. The amount of water coming into the tank and the air going out of the tank needs to be about the same or the tank may expand due to pressure.
Yes, the water tanks can be used for either fresh or grey water systems.
You can use a hole saw just smaller than the threads or very carefully use a knife to cut it out.
If you would like a tank for your vehicle but do not see one please reach out to us. We are always interested in making a new tank design.
