PLEASE READ ALL INSTRUCTIONS AND WARNINGS BEFORE INSTALLING YOUR NEW GLOBAL WATER SOLUTIONS PRESSURE TANK
These instructions have been prepared to acquaint you with the correct method of installing and operating your GWS pressure
tank. Please read and follow these instructions and heed any warnings to ensure safety and maximum product performance. In
the event of installation diculties or need for further advice, please contact the nearest GWS sales oce or dealer.
The following instructions and warnings are subject to periodic updates and should be regularly reviewed on the website www.
gwsusa.com/support for important safety information and instruction updates.
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/o 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 o (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 eciency of the pump system.
