All tanks must have the same pre-charge for the system to function properly. Tanks should be installed on a header to ensure all
tanks receive equal and balanced pressure. Adjust each tank pre-charge as detailed in the adjusting tank pre-charge section.
The system pressure switch or control should be centrally located (see Figure 2.1 & 2.2) in order for the tanks to function
properly.
If the pump short cycles, check the air valve mounted on the tank. If water bleeds from the valve, the membrane has burst.
Please
call an authorized service provider to replace the membrane with factory replacement parts and instructions (see
gwsusa.com/support).
PressureWave SF™ pressure tanks have a replaceable membrane and require pre-charge checks by an authorized service
professional every six (6) months.
Failure to check and adjust pre-charge every six months voids the warranty.

It is recommended that the system is checked annually by a qualified professional. The pressure tank and its connections
to the system should be visually inspected regularly for any signs of water leakage or corrosion on the exterior of the tank or
connection. If any is seen, replace tank immediately. Although our PressureWave™ diaphragm tank design is maintenance-
free, damaged and/or poorly working accessories and tank fittings can adversely affect the tank's performance, as can extreme
temperature variations and age. Therefore, the tank pre-charge should also be checked periodically.

to fill the tank with water.
