Hi, i replaced both hot and cold bath tap washers. both hot and cold sides
feed into the one bath tap exit nozzle. it is the standard u.k. set up. i.e.
boiler outside downstairs at the back of a two storey terraced house and
electric immersion heater tank in the bedroom next to the bathroom and a
cold water tank in the roof of the house. i guess this system is 15 to 20
years old, i.e. the potterton heating boiler is that kind of age.

the turn off supply stop taps to the bathroom taps and the toilet in the
bathroom are in the bedroom. but even turned fully off they do not
completely stop the gentle rise of water out of the bath tap holes once the
washers are removed. to prevent flooding i find if just keep the sink taps
running slowly that are downstairs in the kitchen it does stop this gentle
flow upstairs, whilst i change the washers.

i had new washers ready to go and the change over only took fifteen minutes
or so. great. but now no water comes out of the bath taps. (yes i did
turn on the turn off supply taps in the bedroom again water will now
come out of the bathroom 'basin' taps ok, but only the occasional drip i.e.
next to nothing from the bath taps. grateful for any advice, thanks.
