Hi Guys,
Just finished installing a new shower pump and thermostatic shower value. Hot water is tee'd off the cylinder and cold is on a single continuous run from the cold tank in the loft. Everything worked fine during the tests so Ive now tiled the walls.
When I've tried the shower again I have no cold feed. The hot is fine and running the shower it gets hotter and hotter until the value kicks in then stops at which point if I turn the temperature up it comes on again then cuts out when it gets to the hotter temperature.
I think when I drained down to do some other work after connecting the cold feed I've intruduced air into either the cold pipe to the pump or from the pump to the thermostatic value and now think Im stuck with an airlock.
Any suggestions on how to clear it? and how to stop if from happening again - Id really rather not rip the tiles off the wall :-(
TIA
