OPERATION

This pressure tank has been designed to store and deliver
potable water under pressure in a domestic water system.
It features a diaphragm or membrane design that keeps the
system water in a safe and contaminant-free chamber for
pressurized water supply between pump cycles.
Without a pressurized storage tank, a domestic water system’s
pump would turn on every time there is a demand for water,
even if the demand is small. This frequent on/off cycling shortens
the useful life of the pump. Pressure tanks are designed to store
water when the pump is running and then deliver pressurized
water to the system when the pump is shut off (See Fig. 1). A
properly sized tank will store at least one gallon of water for
every gallon per minute (GPM) of pump capacity. This allows for
fewer pump starts and longer run times which maximizes the life
and efficiency of the pump system.

These instructions have been prepared to acquaint you with
