If a trv won't turn off fully when trying to take a radiator off. And you don't have a plastic cover that you can screw on instead of the trv that will fit .is there anyway around a drain down?
Can anyone advise what type of washer this float valve takes? It has no make or model name on it. Or can the hole cartridge that the washer screws out with be bought?
Do the rubbers in hep2o tap connectors seal up ok after undoing to replace a toilet fill valve. When it was fibre washers I used to swap them. Not sure about these. Thanks for any advise.
