Related to the screed thread.
The boss wants a gas connection to her new kitchen (and an induction
hob!) The most practical route is under the utility floor screed, though
a wall and then clipped behind the new kitchen units.
Gas work seems to have moved a lot since the copper wrapped in hessian
below the screed floor here!
Further exploration on Tracpipe leads to lots of detailed information on
installation, cutting and terminations etc.
Perhaps I should re-phrase my question to.. would a plumber walk off the
job if asked to connect to a pipe laid in screed by the householder?
Apart from bend radii the only gotcha I found is a need to inspect the
pipe sleeve for abrasions and carry out suitable repairs.
That reminds me of the water leak my parents had before I left home. It
was/is a bungalow. We had a carpet fitted in my bedroom which had a cupboard
in the corner where the main stop tap was.
A few hours after the carpet was fitted, we noticed a damp patch on the
carpet in the doorway. It turned out that as the carpet fitter had nailed
the gripper rod into the concrete floor, he had put a nail through the
rising main before the stop tap. The nail was more or less plugging the
It took the guy, with his mate who was a plumber, a long time to fix the
leak. First they had to find the stop tap in the road. Then they had to
trace where the pipe went. It had been buried a mere half an inch into the
concrete floor, and not in armoured trunking. They had to dig up several
feet of the floor either side of the hole to allow enough play to be able to
cut out the holed section and insert a couple of compression joints and a
new bit of pipe, and then fill the channel with new concrete. They also drew
a diagram of where the pipe went and stuck it to the floor in case any new
carpet was ever laid, to prevent it happening again.
You have to question the sanity of burying the main water inlet at such a
shallow depth, in case of any holes drilled into the floor.
At least it was water and not gas...
All the suggestions are wrong including the "drop test" comment. Stop
cutting corners and get yourselves a Gas Safe registered person before
you kill yourself or someone else. Yes I am registered by the way.
I can confirm that in this (rural) area. Due to influence by our
architect we hired our own plumber for an extension, although we should
have got the builder to employ him. He came to do the first fix
(delaying everyone a fortnight in the process) and never returned
despite multiple phone calls and promises. No other plumber would offer
to come within six months. I don't think it was just us, the
electrician seemed happy enough (though he also turned up about three
months after promising to do so).
Why should a person who's gone to the trouble and expense of
getting himself Gas Safe Registered, offer free advice to anyone
other than suggest that he consult another Gas Safe Registered
To do so would not only be unprofessional (in terms of cutting
his own throat) and potentially dangerous - he could be advising
idiots for all he knows - but is probably against their Code
If that be his considered opinion, and policy, then his posting in a diy
group could almost be considered trolling - heckling from the sidelines
without contributing. If he considers he has insufficient information
to specify how the job should be done he could at least say what is
wrong with the proposed way of doing it.
(While we are on the subject of criticism, I don't think too much of the
plumber who repaired a pipe with two buried compression joints, even if
it was only water.)
Yes my dad and I were surprised that he didn't use soldered joints which (if
they are done properly) are less likely to leak. But by the time we spotted
it, the pipe was back in the channel and there were mixing the mortar.
It hasn't leaked in the 30 years since then - or al least, it hasn't made
the carpet damp. They replaced the carpet maybe about 10 years ago so the
state of the concrete was seen at that time.
The whole basis of the Gas Safe Registered system is that while
some members of the public may consider themselves competent to
do such work, the only real test of any such competence is one
conducted by a third party against a common standard. As is the
case with the Gas Safe Register. He's not advising anyone on how
the job should be done, or should not be done because he has no
way of knowing whether the person he'd be advising is actually
competent to do that work. And further that people who haven't
been judged competant by a third party - so that retired
gas-fitters would probably pass muster, shouldn't be undertaking
any gas work at all.
According to a gas fitter engaged in the renewal of the mains
with plastic, which also involved moving the meter, in the old
days gas fitters were paid according to the number of joints
they made. Hence the two dog legs in the supply pipe under
my kitchen floor. Whether true or not I don't know but the
two dog legs were there with no obstructions in the way, and
they'd hardly have done it to use up a one ft length of pipe.
That depends on the level of competency required. Most regulations are a
combination of written rules and working practices. It's not rocket
science to plumb in say a cooker socket, however hard you and others try.
there is nothing to stop you doing your own gas work in your own property.
I fitted my boiler 29 years ago. Last month I had a Smart meter installed
and the leakage tests on my installation showed not a trace of a leak.
I'm not looking to do more of the job than is necessary to prevent
holdups elsewhere. Doorways make running the kitchen gas on the surface
impractical. Through the screed is permitted by the regulations provided
the pipe is properly sleeved. Tracpipe meets the requirements and
appears d-i-y able.
On a slightly hysterical vote of 1 Steph has answered my question.
If you would all kindly stop being critical perhaps a more reasoned
explanation will be forthcoming.
I rather suspect it might be common practice for builders to undertake
simple jobs normally reserved for the skilled trades in order to avoid
