Changed a set of kitchen taps for a lady yesterday, no trace of any internal stopcock since Combi boiler was fitted two months ago. Turned off the water outside.
Had to go back today to finish off another minor job & she mentioned that the water pressure (hot & cold) was down - not just on the kitchen taps but all over the house. Checked the external stopcock which was fully open.
I can only think of two things, either the water pressure is down generally because of a local leak or burst, or summits up with the stopcock.
All the neighbours were out so we couldn't ask them about their pressure.
The stopcock wasn't hard to turn or seized in any way & still shuts off the supply OK.
Any thoughts? I'm guessing muck in the pipe maybe?
