No COld Water in the upstairs bathrooms
Hio There, I have just had to change a shower cartridge as it was leaking internally and to do this had to turn off the water supply and drain the tanks. This I did OK. I have since turned on the rising main and I have cold water downstairs but none upstairs in 2 bathrooms (sink and Bath) but the showers are OK, and the 3rd bathroom where I replaced the shower cartridge all is fine. I assume air in the pipes. I have again drained the system and have opened all cold taps upstairs and turned downstairs to half open and reopened the rising main. All good downstaitrs nothing upstairs.
Just after ideas.
