Drained the hot water cylinder and heating system so I could change the pump, valve and cylinder
Had just the punp and valve to fit when, I find I get home and water is coming through the floor into Kitchen below
The pipe waiting for the pump is leaking water. (so I have plugged for now with quickfix plastic thingy)
Now both tanks in the loft have ball valves tied up and are not dripping, and the hot tap is left on downtairs to make sure nothing was left in the system
so where is the water coming from? It must be going through the boiler and out the other side, but I have a feeling the radiators downstairs will all need draining again before I can finish the work (they were all empty this weekend)
I'm puzzled where the cold is getting into the system
any ideas?
