toilet Cistern leak

[Douglas Sey]

I have a low level toilet cistern, which has never been any bother until just the other day. For some strange reason the level within the cistern is now rising too high and makes an exit out of the overflow pipe, which unfortunately is leaking from a small joint. What is likely to be causing the water to be rising about an 2 centimetres higher than it ever did before. And if I could manage to stem the leak from this overflow pipe with some tcp tape, should I not worry about the water level?

Thanks in advance douglas

If you pull the ball up while it is re-filling you will see if the inlet valve closes properly. To adjust the water level there is an adjustment at the valve end of the ball float arm to vary the level at which the valve is completely closed . The whole point of having the overflow pipe is to allow overflows to escape -if the eis aleak in that pipe then dismantle the pipe and remake using ptfe tape . Stuart

The "Overflow" is now termed a "Warning Pipe" - to let you know something is wrong.

Although you can adjust the level, it is often a sign that the washer / diaphragm has become pitted due to the constant blasting by water at high pressure.

I suggest that you get a repair kit.

You may have a punctured cistern ball, the valve is going US, or the valve assembly/ball is sticking.

Or it might just be that the adjustment screw which stops the incoming water when the ball has risen to the correct height has not been tightened with the nut that accompanies it. That's fairly common.

Yes as the cistern is warning you...obviously. Your problem is with the float valve inside cistern...washer has probably gone ...cheap and easy to install otherwise you can replace the whole float-valve unit for around £12. You should have isolating valve on the cold feed pipe to the cister if so isolate supply to cister and drain by flushing. Simply dis-mantle by turning nut usually plastic. Once loose will be able to dis-mantle float-valve.Simply replace washer and put back into place and turn supply back on...
