Weeping solder joint
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?
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!
