A water pressure tank is an important element in any residential well installation. Properly installed and adjusted, it provides constant water pressure to the house and limits the amount of cycling the pump must do to keep up with the demand. Goulds recommends their HydroPro tanks for use with their pumps. These are bladder style steel tanks with a corrosion resistant polyethylene base. Installation is easily accomplished with a few basic tools.
Things You’ll Need
Threaded galvanized nipple
Multi-port tank fitting (“T” tapped for pressure gauge and switch)
Four-inch brass nipple
Water pressure gauge
Tire pressure gauge
- Wrap both ends of the threaded nipple with plumber’s tape. Make two to three clockwise wraps to completely cover the nipple’s threads. This will reduce the chance of leaks when water pressure is applied.
- Insert one end of the nipple through the cutout in the plastic skirt and into the elbow on the bottom of the tank. Tighten securely with a pipe wrench.
- Thread the multi-port tank fitting onto the open end of the pipe and tighten with a pipe wrench. The two small openings on the tank fitting must be facing up when fully tightened.
- Set the tank in place. The floor under the tank’s base must be level and firm. The tank will become heavier as it fills with water. A solid footing for the tank base is imperative.
- Wrap both ends of the brass nipple with plumber’s tape. Insert the nipple into the base of the pressure switch and tighten. Insert the open end of the nipple into the opening on the tank fitting nearest the tank and tighten.
- Wrap the end of the water pressure gauge with plumber’s tape. Do not cover the opening on the bottom of the pressure gauge with any portion of the tape. Thread the water pressure gauge into the opening furthest from the tank on the tank fitting and tighten.
- Remove the pressure valve cover on top of the tank. Use a tire pressure gauge to check the bladder pressure in the tank. The bladder pressure should be set at 2 psi below the pump’s cut-in pressure. If the existing pressure in the tank is too high, release some air by pressing the center stem in the air valve and check again. If the tank pressure is too low, use a bicycle pump or compressor to raise the pressure to the desired level. Replace the pressure valve cover when finished.
- Connect the end of your plumbing supply line to the tank fitting.
- Wrap the threaded end of the shut off valve with plumber’s tape. Tighten the valve in place in the remaining opening on the tank fitting.
- Turn on pump and check system for leaks.
