overflowing water cisterns





i have been plagued by this problem for quite sometime - i think it has been more than 3 months already - by not one but two overflowing water cisterns; one in the toilet upstairs and the other in the toilet downstairs.

i have tried adjusting the screw on the valve and the washer assembly. i have tried varying the position of the float (ball). i have even tried replacing the ball - which i thought could be damaged - with a new one. i also tried cutting down the rate of water flow into the cistern. i even tried flushing the whole system. nothing works.

the problem is the water level goes above the outlet valve and this causes the overflowing. so, this is not a problem of a leaking washer on the valve.

i think, short of replacing the whole cistern/system, there does not seem to be a solution in sight.

i have since fixed the problem of the overflowing cisterns. simple. i just used a piece of plastic and covered the outlet valve in each case. so far, so good.
