Replace tap washer. Can't stop water

ormus

as the OP has a combi boiler, its unlikely he has any CWS tanks in the loft.

If you have a combi boiler there are pipes going in underneath.

All but one have isolators fitted (the one that doesnt is for gas) & just turn each one of them to a horizontal position.

as above. find the rising main stop coc k.
the one under the kitchen sink, may not be the main SC.

failing that find the one in the street.

I have seen stopc ocks put in after a branch

ormus

i know.
ive got two in my bathroom cupboard!
one is the main SC. and the other was a branch for the old CWS in the loft.
all ripped out now. i now use the second SC branch for the shower cold supply.

I will check that out thanks!

I have a Greentstar Junior (Worcester) boiler, so if anyone knows how to turn off the cold water supply that would be great and if it will affect the boiler ie break it.

Have a look underneath.

By isolating the cold water going in you isolate the hot water coming out. It will be one of the middle ones but just do them all. You will need a flat head screwdriver as the isolators have screw heads. If you do all of them you wont forget which way/one is which when you are finished.

Make sure the boiler is off. & it will not cause damage unless its damaged already.

Then do the stopc ock under the sink again.

Then tryout the taps & let us know.

Remember to turn the isolators under the boiler before you turn it back on.

It might be worth turning off the main in to the boiler rather than all three as some valves don't like being used for the purpose they were designed for and they leak.

The functions for the valves and the pipes they are connected to are identified by symbols stamped into the fixing jig .
DHW out is the only one not controlled by a valve Gas is.

There is no substitute for finding the incoming mains supply stopcock.
One day you will need it in a hurry.;)
I would be more concerned with air in the mains supply when you turn it back on. Leave the boiler off until all air is cleared and the taps run clear.

The isolation valves are there & are designed for isolation.

& more than likely the OP has no mains stopc ock.

More than likely whoever fitted the combi or a new kitchen put a branch
in before the stopc ock.

So you have isolation in the road or perhaps at boiler & under sink together & maybe one other buried somewhere stupid hidden behind a unit or under a floorboard..


There are no other solutions.

That doesn't mean they will not leak.

They can and do.
