I have a Reliance Thermoguard UFH blending valve. Flow and return connections on the valve are 3/4" BSP F and boiler pipework is 22mm copper.
I am using a bog standard brass 22mm compression to 3/4" BSP M coupler to join the pipework to the blending valve.
Unsurprising to me, the BSP threads weep, despite application of PTFE and thread sealant.
What's the right way of doing this connection? BSP taper, something with O-ring? I'd rather not just apply more welly doing it up. Its pretty tight already.
I knew it was going to leak when I put it together but couldn't find a bits to do a better job.
Thanks!
