The standing pressure at the outlet is regulated by the meter governor.Hi Guys,
Thanks to all who have commented so far!
Today BG fitted a shiny new U6 gas meter to the service provided by SGN.Actually, it's a reconditioned one but it looks very nice nonetheless.
Standing pressure at the meter was 23.5mbar.
I took the opportunity to measure the run of SGN’s service pipe which is nowburied. It's longer than I thought. Effective length is actually 30m and it's32mm yellow PE.
The difficulty remains what size pipe to specify to connect the meter tothe house which is a further 30m away (allowing for upstands andbends at each end). The supply will feed a 24kW WB combi and a 9kW gashob.
My instinct is to have it run in 63mm yellow PE despite it being five timesmore expensive than 32mm. My layman's logic is that if this doesn't provideenough gas flow at the house, then it will be down to SGN to upgrade their 32mmservice. Or am I being naiive in believing this?!
Also, this assumes there is a way of checking the gas flow rate withoutany of the appliances being fitted. Am I correct in believing that there is?
As ever, your comments and advice would be much appreciated. Having made somany costly mistakes elsewhere on the build, I am determined to getthis aspect right first time!
Cheers, Jonathan
Changing the service would not give you any extra. The main is usually fed under a higher pressure anyway.
You should have really got the meter installed closer to the boiler.
