Went to a simple basin connect in cloakroom in a 1880's terrace house.
Went to do cold first, there was a lead pipe out the ground with stopcock looking like it feed the cloakroom/utility room alone with a really handy rain valve just above it. Turn it off, open valve water comes out... water comes out.. 10lts of water out... ok - its not stopping - just a trickle 0.5lt a min. , open stopcock, gushes as expected, go outside, turn off mains to house.. same trickle, turn on stopcock still a trickle. I couldn't stop it.
Figure ok - lets look at hot - into airing - close gate valve to cylinder, drain taps.. trickle - same as cold. close of riser to tank, drain tank.. still a trickle.
Took many attempts to finally get a solder on the cold T, just wouldn't drain with the drainvalve open too.
The hot I left the taps open and just cut the pipe where I wanted and cut again to throw a service valve on, got soaked but least I could solder after.
Not nice.. I'm thinking maybe a burst pipe forcing just enough water up the pipes but hot and cold?
I couldn't get into the loft space to see what was happening there, thats why the riser had a valve in the airing.
any thoughts?
