I have just fitted a new towel radiator and it has started leaking where the pipe goes into the bottom of it, it only leaks when the heating is off and the radiator is cold, l have re-taped it twice with ptfe tape and it is still leaking l really don't know what else l can do.please can someone help.thank you

I am presuming that you have fitted the radiator tails which go into the towel rail and on the valves correctly with ptfe,take off the tap heads and see if it is leaking around the gland packing nuts,if so and they are new, tighten them a pinch, it doesn't leak when it's hot as the heat makes it expand slightly.

hi thanks for your reply,l have put plenty of the tape round the threads and tightened up the connector but unfortunately it still leaks the inlet one is fine but the outlet one will not stop leaking.

have you checked the packing gland nut,take off the handle and you will see a brass nut
