Water Installation Check
Go down the following water installation checklist:
Are all screws and clamps properly tightened?
Is the water supply pipe flushed?
Was the water installation correctly installed?
Can the blow-down water drain freely?
Was the water discharge correctly installed?
Is there no leakage from the water supply pipe and
water discharge?
Warning:
Flush the water supply pipe before connecting to the
solenoid valve, especially a newly installed pipe. This prevents
premature damage.
