A leaky cistern can be repaired without going to the expense of calling a
Firstly lift the lid to see if anything has been caught or jammed. If the water
seems to be going down the overflow, there are a few adjustments you can make,
like lowering the water level. Or, on an older cistern, bending the float arm
down can solve the problem. If itís not going down the overflow and the other
adjustments arenít working.
You might have to replace one of the washers or possibly the float valve.
To do this, turn off the water tap, usually located near the system. Then remove
the float arm. Next remove the flushing mechanism, which allows you to check the
condition of the sealing washer. In this case, the washer is split. To replace
this washer pull it off and slip on the new one. Then put thecistern back
together in reverse order.
