THE SYSTEM IS ALL CONNECTED BUT NO WATER IS COMING OUT?
check that the ball valves are not in the shut o
ff
position. Sometimes you may have to check
whether the tap is turned on also! ( you will be surprised how many people will make this er-
ror) Make sure that the water is going through the system via IN - OUT direction flow. Plug-
ging the system in reverse may not flow any water and block up the system with Resin. If this
happens, unplug thew system and clean the inlet outlets to be sure of good flow.
HOW MUCH WATER PRESSURE IS OK?
The tank housings are rated at 140 psi maximum and the unit is leak-tested to handle this
amount of pressure. Typical residential regulators reduce pressure to 65psi and both your
Spotless Water unit (and your house) may be in jeopardy if operated above 140psi.
DOES THE RESIN HAVE A SHELF LIFE?
Yes, the resin has a shelf life of approximately 12 months before it will start to lose e
ff
ective-
ness.
HOW DO I STORE A PUREWASH SYSTEM?
Between use make sure that the unit is sealed on the inlet and outlet ports from air to the sys-
tem. Failure to store system in this way will reduce shelf life of the PUREWASH system mak-
ing ‘Spot Free’ Water.
