Further to my post about cooker hoods.
I have a new gas supply in copper pipe clipped at skirting board height
on one side of my kitchen. I'm now contemplating locating the hob that
the gas supply was installed for on the opposite side of the kitchen.
Can I, as suggested by the installer (my CORGI plumber), simply Tee into
the supply and run a new pipe across the kitchen buried in the concrete
screed? If so, how deep does it need to be, how do I protect the
(copper) pipe from the corrosive effects of cement and what other
protection should I give the pipe?
That's what I suspected. I had a conversation with my plumber last night about
this last night. He said bury it in the screed after wrapping it some 'Denso'
(?) tape - it's an evil grease loaded tape that will protect the copper pipe
from the agressive effects of the backfill, speaking of which; I guess it should
be a fairly weak concrete to allow for subsequent excavation if necessary - any
idea what strength? He also said that I should remove the gas meter after
having attached a jumper lead across the two pipes.
Is Denso the right name.
If Denso tape says it is suitable for that application and you apply it
as per their instructions then it should be OK. The rules on burying gas
pipework in screeds etc are in BS6891, also in the CORHGI book
'Essential Gas Safety' and CITB and Viper training documents and
doubtless other documents besides. You must make sure the pipework is
sound (gas tight) before wrapping and burying it.
Why? Are you going to solder up close to the meter connection? The
jumper lead across any break bit is OK. Sounds like you could do with
reading Ed Sirret's docs on gas pipework (Google)
Well having read the FAQ (Gas fitting FAQ
I'm not sure that I am sufficiently competant. SWTMBO is certain that the
plumber should do

It's a bit more than a good idea, it's a necessity.
Note for the floor pipes that the they must be protected from corrosion by
the concrete, this
means sleeving it in felt or wrapping 'denso' tape around it (yuk).
The pipes must be gas tightness tested before applying the sleeving.
