Well Tanks

About

A properly sized well pressure tank is one of the most important components in your well water system. It stores pressurized water so your well pump doesn't cycle on and off every time you open a faucet, protecting your pump, maintaining consistent pressure, and extending the life of your entire system. We carry Amtrol Well-X-Trol steel diaphragm tanks (the industry standard), Pentair WellMate fiberglass composite tanks (rust-proof), and the WellMate UT120 retention tank for chlorine contact time. All tanks ship free to the lower 48 states. Not sure which tank you need?

Types of Well Tanks There are three main categories of tanks in our lineup, each designed for a different use case: Steel Diaphragm Pressure Tanks (Amtrol Well-X-Trol) The classic captive-air pressure tank. Inside the high strength steel shell, a flexible diaphragm separates the water from a sealed, factory pre-charged air cushion. When your pump fills the tank, the air compresses; when you open a faucet, the compressed air pushes water out. Amtrol invented this design and Pro Series tanks carry a 7 year limited warranty. Available from the 20 gallon WX-202 to the 44 gallon WX-250 , including the 34 gallon low-clearance WX-205 for crawlspaces under 4 feet. Fiberglass Composite Pressure Tanks (Pentair WellMate) Same captive-air principle, but the shell is continuous-strand fiberglass over a seamless polyethylene liner, so it cannot rust, even in a damp basement or a coastal well house. Lighter than steel, easier to maneuver, and backed by a 5 year limited warranty. Available from the 20 gallon class WM-6 and 40 gallon class WM-12 up to the 87 gallon WM25-WB with internal bladder.
