Thanks AlanE, I have spoken to the guy that did the pressure test and he is confident there is no restriction in the pipe. Increasing the supply pipe would be alot of work as it is some distance back to the boundary meter (40m) plus there is no guarantee this would 'solve' the problem. The...

There is 7 bar static pressure, but only 1 bar running pressure when only 4 outlets are open. It is likely there could be more than 4 open at any one time. There are only 6 showers and probably 3 sinks and 10 hand basins. Not much more than a very large house I suppose (there are no baths)...

What makes you say that, what size are you thinking (it isn't a hotel) its a small community building.

Had a pressure test done on a school building (standing pressure was 7 bar and working pressure was 1 bar with 4 taps running) the flow rate was measured at 30 litres per minute. Is this good pressure? the building is being extended and I am worried the school will be short of water...

I have an old Vaillant gas fired water heater upstairs and it keeps cutting out half way through filling a bath or having a shower. Sometimes it will be ok and other days it will cut out after say 30 seconds of running a hot tap. It may be me but it seems to be worse in the winter when I...

I would prefer to just move the meter (this is needed as the existing cable would run under a new extension), but keep the existing consumer unit in its existing location. I assume a sub-main can then run from the new meter underground to the existing CU position and any 'new ' CU's (to cater...

Currently have a 3-phase cable supplying the house but it seems there is only one of the phases connected to a single phase meter at the moment. The house will need 3-phase available to cater for a large extension and pool, firstly, can the supplier come and replace the single phase meter for a...

What are you thinking of doing? Providing a hot water system to large domestic house Mains pressure hot water? Yes, off boosted supply tank and pump set Is this a small hotel? No What is the usage? 10 people max (5 beds) Will all showers be on at the same time? Could be.

Large house with 5 double bedrooms Bathroom - 1 large bath, 2 showers Bathroom - 1 large bath En-suite 1 - shower En-suite 2 - shower En-suite 3 - shower What sort of HW cylinder size would you recommend, was thinking 10 people max. 45-50 litres each, 450-500 litres (2 cylinders...

There is a control valve just outside the property on the outside wall, and the tank is about 40m away (is there another valve at the tank?). I assume the control valve near the house will need to be repositioned along with the pipe to the house that would be in the way of the new extension?

Can a CORGI registered plumber carry out the alteration work, or will it need to be the LPG supplier?

I take it thats a NO then, cheers guys. ps well done on the smoking!

Can a LPG supply pipe run under a building? Its current position is ok, but there is an new extension to be built which will be right over it. Would it be able to be run in a perforated duct of some kind? :)

I hope you aren't a qualified Electrician

Are you sure?

It is an old house it dates from the Georgian period. I am not certain when it was rewired, probably within the last 15-20 years. There is a large extension being built which will replace most of the wiring to the ground floor, including a new distribution board probably, however I don't really...

I have some old socket sin my property which don’t have the switches on. Is it possible for an electrician to replace them with a modern switch socket? Is is a simple job for them? :)

Thanks for the info. Just out of interest, where do you guys get this information from? I guess you can reel these figures off in your heads!!

Thanks, the duct containing the gas pipe will be 250mm x 650mm x 2400mm., this rises from ground floor to the floor void above, hence the 2400mm height.

Thanks very much, the volume info would be useful.
