The electric element in my neighbours towel rail has failed and needs to be replaced - this in itself is no problem. I believe its possible to isolate the towel rail by merely clamping the flexible pipes that feed the rail from the c.h. system - can this be done whilst the central heating system is up and running (whilst water flows thru the pipes) or is it best done with the c.h. off. Also can anyone post me a link to the clamps I need. When and if the clamps are applied the towel rail will need to be drained before the old element can be replaced with the new - when the clamps are then removed will this not cause an air lock in the system ?? -
