How can i find the main water turn off; the cold water tap, for the bath, needs a new washer

You will have to turn off your water mains and strip your mixer tap. It is possible that the seal (if it is an older tap with a rubber seal) has become stuck or the threaded part that turns it has gone faulty. If it is a modern tap with ceramic seals, check the operation of the mechanism and see why the ceramic seal is not being opened.

no problem at all using only cold. Most washers only will fill with hot water after that all other cycles use cold.

Hiya,
this can be a water presure issue with your mains or maybe the inlet tap to your machine is not open fully i would surgest checking the connection tap is open fully & allowing the maximum amount of water through to your machine.. if you sink taps run slow then this would be a sign of your water mains presure needing attention.. presure can also be reduced by using water around the house at the same time as the machine is on for example running a bath, dishwasher, flushing the toilet etc.

Hope this helps

you may just have to replace the hot/cold stem

Remove the tap outer cover. Take out the barrel & inside there is the washer on the end of a screw which slides in and out when the tap is turned. This could have been turned too far out and will not go back in. Clean both the screw thread and inside the barrel, lubricate with petroleum jelly or similar and reassemble & test before replacing the barrel. Again lubricate all threads.
Alternatively buy a new barrel

possible that the pipe's are not,secured properly in wall. and you did not say what kind of faucet you have, but if it has washer's,the screw's that hold them, may be loose.

Was the tap shut-off very tight and the tap is turning but the main shaft may not be turning. Check the hot tap mechanism and compare it to the cold tap.

change the washers first if that don't work change the inserts buy all at same time and return if not needed . Thank you for useing fixya please rate me

hi it sounds as though its stuck due to verdigris & scale, a common problem.if you break it all thats likely to happen is the spindle will shear off, which will mean a new one anyway. If you dont want to do this I suggest you turn off the water to the storage tank & open the cold taps till the water stops you can then replace the washer.whilstthe water is drained i suggest a new valve to be fitted for future servicing etc, also it might pay you to fit a service valve on the supply to the tap.

try turning on both taps and see what happns,some of these whirlpool machines need both taps on but mainly when running on cold.
