AIR PRESSURE TANK INSTALLATION
When using a pressure tank with your pump, we recommend that you install a captive air
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 tahty 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.
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.
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 ,
than close the fawcet ;
- Close service line in gate line ;
- With a car tire pump, inject air into the snifter valve located in the
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.
