i have just replaced my bath water mixer. Unfortunately i cannot stop water leaking out of both hot and cold water nuts where the copper pipes connect to the mixer inputs.
I have tried using special wrenches, PTFE tape and silicone sealant, but to no avail :(
what can i do to stop the leak? the space behind the bath is really tight making the use of a conventional wrench impossible. would the use of Speedfit/B&Q plumbeasy system plus a 22m coupler do the trick? or shall i just put in more oil seals and connect the mixer to the existing copper pipes?
