leak
Posted: Tue Dec 16, 2008 3:31 pm
My combi-boiler has a amall leak, only very slight "weep" when the boiler is not working. When the system is on it is O.K., Plumber advised that is weeping from aroud o-ring where pipe goes into heat exchanger but said not worth all hassle of trying to dismantle and replace. Was wondering is it worth putting leak sealant into system to try and cure problem??
