too low. Tank is in alarm

condition.

No feed water available.

Check that water supply

treatment plant is running

and that water is available.

Check that isolation valve is

open.

Water Feed PAV is not open. Check that air supply

pressure is correct.

Check that PAV solenoid

valve is energised.

Operate manual override on

solenoid valve to check

operation of valve.

Manually operate valve via

Water Level in tank is too

high.

Tank is in alarm condition.

Water feed PAV has failed to

close.

Isolate feed water system

and inspect valve seat for

Water supply pressure

exceeds maximum

differential pressure of valve.
