When using a pressure tank with your pump, we recommend that you install a captive are
tank where the air pressure is injected at the factory (See our installation diagram). This air,
which is in addition to atmospheric pressure, increases the ability of the tank to deliver more
water between the on/off cycles. This provides greater efficiency for your water system.
Connect the pump discharge to the T, using adaptors and braided hose, then, connect the
other side of the tank T to your home’s plumbing distribution line.
Make sure that the precharged air pressure (before connecting the tank) is 2 PSI less
than the starting pressure set on the pressure switch of your pump.
If you adjust the air pressure after the installation, follow these steps:
- Check the starting pressure of the pump on the pressure gauge;
- Disconnect the power to the pump;
- Open nearest fawcet to the tank and relieve all pressure in tank, then close the fawcet;
- Adjust the air pressure of the tank (by pumping or removing air at the snifter valve)
2 PSI below pressure switch “ON” setting;
- Turn power back on to pump.
Your tank is now well precharged. Run the pump through a few cycles
to verify that it works properly.
Other types of tanks may be used, such as galvanized standard tanks, epoxy or glass
lined tanks. However, these products do not achieve the benefits of the captive
air tanks.
Epoxy or glass lined tanks with float have to be precharged by the
installer. Assuming tank is plumbed to pump and all connections
are checked for leaks, follow these steps:
- Run pump through one complete cycle, until pump shuts off;
- Disconnect the power to the pump;
- Open nearest fawcet to the tank and relieve all pressure
in tank, then close the fawcet;
- Close service line gate valve;
- With a car tire pump, inject air into the snifter valve
located in tank. Watch pump pressure gauge and stop
pumping air when pressure reachs 2 PSI below pressure
switch “ON” setting;
- Return power back on to pump;
- Run pump through one complete cycle;
- Open service line gate valve.
Your tank is now well precharged. Run the pump through a few
cycles to verify that it works properly.
Galvanized standard tanks require an air volume control and are to
be used with a jet pump. We do not recommend the installation of
this type of tank with your submersible pump. This type of
galvanized tank is recommended only with piston pumps.
