How to Fix Leak
I have a leak in solder connection on 1 inch cast copper/brass? "T" .....
this is hot water pipe for Boiler/home heating system..... I have made several modifications and when I refilled with water and pressurized found very small leak....about 5 drops a minute.....I thought I could repair with epoxy putty, but did not work...tried twice and still leaks, seem like the epoxy putty just does not seal the uneven surface of the cast copper/brass "T" fitting...and after 1/2 hour or so starts leaking again.........I know the right way to fix is to drain system and re solder connection, would like to avoid this if I can till next summer when I have to drain again anyway........Is there another product that might work? |

How to Fix Leak
50 years ago, I fixed a leak in a pipe supplying a rad in the middle of
winter when we couldn't drain the boiler, plus it was a threaded joint that was slowly leaking, which would mean disassembling a lot of piping. I took some very small diameter electronic grade wire solder with rosin core, and a medium sized screwdriver with a new flat bottom to the tip, not rounded over from use. Wrap the solder wire around the joint and tap the solder into the area where the leak is coming from to compress and force the soft wire solder into the joint where the water is dripping. It may take a few tries, and it may not even work, but give it a try. This method was used after seeing a cast iron drain pipe sealed with poured lead, the final waterproofing is to hammer the lead tight against the pipe edges with a square ended tool. It worked for me, it may work for you. wrote in message ... I have a leak in solder connection on 1 inch cast copper/brass? "T" ..... this is hot water pipe for Boiler/home heating system.....

How to Fix Leak
Go to auto parts store get piece of heater hose split small piece of hose
and apply it over the fitting so that the split is away from leak then put heater hose clamps 2 side by side close together over leak and tighten them TIGHT I think it will make it till you want to drain it.
