PRESSURE TANK INSTALLATION
The purpose of the pressure tank is to allow a certain
amount of water to be used before the pressure
drops enough to cause the pump to start. Without
a pressure tank, the pump would start and stop
constantly, every time water is used.
NOTE: Use thread tape and thread paste on all
threaded connections.
1. NOTE: Check the air pressure of the tank with
a tire gauge before the system is charged
with water. The pressure should be 2 lbs. less
than the low pressure cut in on the pressure
switch. For instance, for a 30-50 switch, set
the tank pressure at 28 lbs. or less. (Fig. 1)
2. Apply five wraps of thread tape and thread paste,
insert a tank tee through the opening in the
bottom of the pressure tank, and tighten securely.

3. Connect a 3/4 in. fitting to the 3/4 in. opening on
the pipe tee. (Fig. 3)
4. Connect a 3/4 in. pipe and union to the 3/4 in.
fitting. (Fig. 4)
