Pressure Storage Tank PST Series Important for high performance water pressure systems. A pneumatic pressure charge, matched to the pump cut-on pressure, prevents tank waterlogging by separating the air charge from the system water by means of a rubber bladder. this results in a smooth delivery of pressurized water, even temperature mix in showers and reduces pump cycling. Fresh or salt water use. May be mounted in any position (including upside-down) and anywhere in the boat's cold water plumbing after the pump. Stainless steel straps and mounting hardware included. Air valve, located at opposite end of tank from plumbing provides for easy checking and adjustment of the PST air charge. Standard tire pressure gauge and pump fits the air valve. Several small tanks may be installed in series where space is a problem for one large tank.
