Weeping solder joint

Anonymous user 23/02/2024 - 3.02 PM

Hi, I took down my ceiling recently and may have nudged the central heating pipes in the process as one of the solder T joints is now weeping. It is quite an awkward position to get at and replace, and i have only ever worked with compression joints and plastic fits. Is there some type of sealant that can be used which i can apply to the joint to stop it from weeping without the need to drain system and replace joint in full? thanks

Are you a tradesperson and able to answer this question?

No not really, you can get additives to add to boilers to stop little leaks ( a bit like radweld for cars). I'm not sure it would be up to stopping a weep on a pipe and I'm never sure they are a good idea due to possible clogging. It is very difficult to re solder wet piping (nigh on impossible!) If I were you i would drain the system and pop a compression joint on!
