I posted before that I've had to top up the central heating pressure more recently.
I initially isolated the boiler and thought it was a leak from the boiler as I got a pressure drop. I then realised I probably didn't have the system completely cool when I isolated it like an idiot. Did again, topped to 1.5 when completely cold, left for 48 hrs and it didn't move at all. When I opened the valves the pressure dropped on the guage indicating a pipework issue I think.
Balloon over prv pipe dry.
I've been under the house and lifted a few easy carpets upstairs, no obvious water loss. None from radiators or valves.
I noticed there was an access panel in the boxing carrying pipes from the boiler to upstairs so in desperation I stuck my camera in and took a picture. The angle's a bit odd but they are pipes running upwards in boxing then I think there may be a leak at an elbow at the top under the bathroom floor.
My question is have I found it, or does this look like something you might get after soldering? It looks not right to me! It's on a pipe that gets hot when the water is on, 2 other pipes get hot with the heating on so I presume these are pipes heading to the cylinder coil.
So does it look like a leak and would a leak on this pipe cause my pressure loss? I hope so, finding this little leak has taken over my life!
Sorry that's a long post to ask a simple question! It's a plumber next to get to it and hopefully fix if you think I could have found it.
