Hello everyone
I wonder if anyone could help me get some answers…
Last year I had a new boiler installed. Before I had an old fashion boiler (installed in the lounge) so most of the system had to be replaced. Pipes run from the meter to a junction giving one branch to a cooker and one to boiler. I think that only pipe after this junction (pipe going to the boiler) was replaced by plumber fitting new system.
Last week I had an gas engineer for boiler inspection. He found that boiler inlet working pressure at high rate is only 15mbar whilst outlet pressure from the meter is 20mbar.
He suggested that there is a problem with pipework between meter and boiler, probably undersized pipe. I checked the system and it looks like there is 22mm all the way except narrowing in few joints. I also noticed that pipe is narrowed to 15mm directly before it enters the boiler. Please see pictures uploaded. Would 15mm pipe on few elbows/joints cause such a big pressure drop or could it be something else? It does not look like the system was flashed at installation or inhibitor was added but I wonder if this could be a reason.
I have no idea about plumbing and gas systems and I dont want my plumber to take an advantage of it.
Please advise
