Bit off topic, but I always get top advice on here so it's worth a shot. Basically the diverter valve on my boiler stopped working properly, so I thought to replace it. Got the valve, took the old one off without too much trouble and new went on easy enough. Job done? Nope! Between the diverter valve and the heat exchanger is a weird coupling assembly that appears to be one pipe pushed inside another pipe. This coupling began leaking when I put the water back on, and only got worse as I attempted to tighten it up.
Took it out completely and replaced the fiber washers, but it's just not playing ball. I have ordered the replacement part and it seems to come as two pieces which slide together and I don't get how this isn't just going to happen again? Would it be foolish to try soldering it?
This is the piece in its assembled and deconstructed forms..
