How to Install a Residential Pressure Tank
- 1). Choose an installation location for the pressure tank. Make sure the location offers protection from temperature extremes and allows easy access to the supply line from the well pump. Use a level to make sure the tank will sit flat.
- 2). Turn off the power to the well pump. Drain residual water from the lines by opening the lowest tap or faucet in the system. Use pipe wrenches to loosen and remove a section of the supply line in the location where you’re installing the pressure tank. Catch any remaining water in a bucket.
- 3). Clean the ends of the supply lines with a wire brush. Wrap two layers of Teflon tape clockwise around the threads. Connect the supply line using a pipe tee. Tighten the tee securely with a pipe wrench.
- 4). Choose a section of pipe long enough to reach from the tee to the pressure tank. Wrap the threads of the pipe with Teflon tape and attach it securely to the tee. Attach an appropriately sized pressure relief valve to the other end of the pipe and tighten the union nut on the valve securely onto the supply pipe.
- 5). Wrap Teflon tape around the threads of a pipe elbow, and screw the elbow into the port on the bottom of the residential pressure tank. Tighten the elbow securely with a wrench. Choose a pipe long enough to go from the elbow to the pressure switch. Tape the ends of the pipe and thread it into the elbow. Tighten it securely. Connect the other end of the pipe to the pressure switch and tighten the union nut on the valve onto the pipe.
- 6). Set the precharge pressure for the tank and adjust the pump pressure according to the instructions included with the tank and pump. Turn on the power to the pump.
