I'm having a new gas boiler installed.

Currently, the gas meter is in the garage, and the new boiler will be
located in the house, in place of the old one .

The house & garage are seperated by a 3ft wide path.

The existing gas pipes (There are 3 x 15mm pipes, feeding the gas fire,
cooker, & existing boiler) running under the path between the garage & the
house.

The plumber tells me the gas pipe between the garage & house has to be
replaced with 22mm pipe.

My questions a

1) What precautions have to be taken when running pipes under the path,
should they be ran in some kind of protective ducting ?

2) Is it ok to use copper pipe, or should iron pipes be used ?

3) Will one 22mm pipe between the meter & the house be sufficient ?

(The existing pipes don't appear to be protected in any way, and I wan't to
make sure the plumber complies with the relevant regulation(s) )

TIA, woodglass

ok, i agree the system should be upgraded to current standards, you need
also to have an aditional emergency control valve (aecv) at the point
where the gas enters the property/house, on the inside (this must be
accesible in an emergency), the size of the pipe depends on the load
placed on it by the appliances and the pipe should be 375mm under
gardens and heavy traffic areas and 40mm under concrete paths/slabs
when used for foot traffic (both measurements from surface)

copper pipe should be sleaved, and i would recommend 22 or 28mm copper
pipe with bends if possible or soldered joints, the route of the pipes,
meter and aecv should also be permanently displayed beside the meter and
also the aecv, kinda telling any dumbass the situation with the gas
supply! in addition the ground must be marked with tape above the gas
pipe to show its route (obviously under the final covering of grass of
slabs etc

hope this helps

The pipe does not need to be sleeved. Direct burial plastic coated or
wrapped in denso is enough. There are some dedicated direct burial
pipes that only require compression joints.

copper pipe should be sleaved or wrapped! it is in the regs si number 2451!

I'll look. But if that is the case then direct burial pipe should be
sleeved, as pipe is er, er, pipe.

I would go for the stainless direct burial pipe as if a shovel hits it, it
can resist the force better.

Surely, if a corgi registered gas fitter is installing a new boiler he
should be uptodate with all the regs and the op is worrying for nothing. !

I tend to agree that there is some breakdown in the trust between the OP
and the fitter.

If the OP has concerns that the work is/has not been done right then they
can ask CORGI to check it over. BUT If I had a customer like that I would
firstly make sure that the work was by the book and then some and secondly
that I would have as little to do with them as possible from then on.

Bzzzt!

use bituminous paint or PVC wrapping tapes. It is therefore not

Are you kidding?


No I am not, or was that a tongue in cheek response ?

Ed said, quote 'If the OP has concerns that the work is/has not been done ri
ght then they

I was chatting to someone the other day who thought that the gas fitter had
done something wrong on an installation and had had Corgi inspect the work.
In this case, Corgi passed it 100%.
