    On a job at the moment, which currently has no gas supply although there is an existing gas U16 meter at the boundary supplying another building on the same site. The building is an extension to an existing café, the installers are looking at connecting the gas off the 63mm supply after the meter and running it to the new extension.
    Can we split the supply in the ground, one above ground entry to the plant room and one above ground entry to the commercial kitchen room i.e. two entry points into the same building with two separate isolator valves? This will mean to isolate the full building there will be two lever valves to close, can anyone see a problem with this? the kitchen and plant room are quite far apart so running the gas to each area internally would be difficult.

    How would the fire brigade know that there are 2 gas entry points & valves for the same building?

    Yes you can, but you will need a chamber with an isolating valve after the branch on both legs. Plus a means to purge and test each leg.

    The kitchen must have an solinoid valve and knock off button by the exit door.

    A specialist job, so not for you everyday commercial rgi

    And a bigger meter sounds in order as well.

    And this question should definitely be in the combustion chamber

    Let me see know we could just lop off the 63mm and fusion weld a branch in here add a few fittings and a couple of valves for luck :rolleyes: Ooooooops hang on I forgot to purge the existing pipe. :LOL:

    You remember that resturant that use to be in the high street :rolleyes: The burnt oak, that's the one, well it aint there no more :LOL:

    Its not uncommon for more than one supply to enter a property from one correctly sized meter...but your installer knows that..right :confused:

    Also your installer knows about labeling the new valves and the labels requirements...yep :confused:

    Oh and of course hes just finishing off his line diagrams for the carcass and placing them near the meter. :confused:

    I wont even think about the interlocks etc for the kitchen which he's obviously clued up on.

    if i was the main developer/owner/Mech contractor, i wouldn't be at all worried that all these things are being asked on a DIY forum :eek: :eek: :eek:

    Be aware that this poster is not CORGI registered and does not do practical work himself.

    He seems to design and specify systems for a building firm.

    Hi Tony, I do not know the laws /code in your area but here the master plumber /gas fitter is totally responsible for properly sizing of the piping once the gas supplier receives a load letter and brings the service to the curb.


    On my profile you can see some of the boilers /gas piping headers


    The same with drainage even if the plans are approved most professionals will recalculate the developed length and the BTU input starting at the furthest appliance boilers /gas fired water heaters / stoves and also figure in the drainage and water supply.

    Some designers are just not up to speed when it comes to knowing the local conditions so they always place a disclaimer stating the Master plumber / Master gas fitter shall verify all piping size requirements.

    Even engineers are told the installing plumber will have the final responsibility.

    Nothing personal it is just the nature of the beast that the gas fitter is licensed thus we should be held accountable

    Can you picture it at a client meeting, with all these suits sat around the oak table.

    I think one has to be very choosy and extra careful when taking or giving advice on the net...


    The masterplumbers site allows for all kind of terrible advice to be given out to the DIY especially when a DIY tells another how to cut corners
