Troubleshooting
Problem
Probable Cause
Solution
Insufficient water delivered to WC pan
Water supply pressure issue
Check inlet water supply pressure and
that a minimum of 300kPa and
a maximum of 500kPa is available.
Incorrect water supply pipe size
Ensure that a minimum 25mm water
supply is connected to the flush valve.
If multiple flush valves are supplied off
the same service, refer to the hydraulic
design and subsequent pipe sizing
to allow for probable simultaneous
demand.
WC pan flush volume issue
Ensure the WELS rating of the WC pan
is comparable to the WELS rating of
the flush valve.
Incorrect timing setting of flush valve
Master-Trol at stated inlet pressure.
