Importance of Checking Pre-Charge

Checking pre-charge is an essential step in installing a pressure tank. The standard pre-charge in a Flexcon pressure tank is 38 PSI. For proper installation, you want to make sure the pre-charge of the tank is 2 PSI below the cut in setting of the pump.

18 PSI for a 20/40 system

28 PSI for a 30/50 system

38 PSI for a 40/60 system

Every Flexcon pressure tank that leaves our facility has gone through a multi-phase testing system to ensure each tank has been made to the highest standards. In the rare occurrence that you receive a tank with no pre-charge, we do not recommend installing it as there could be something wrong with any tank that loses pre-charge in the box.
