Gas supply into new build
Discussion
This came up on my snagging report for my new house
The snagger thought it looked dodgy being copper pipe wrapped in black tape.
Is this ok do you think?
Where the gas pipe comes in from the street, is inside a plastic tube and looks much stronger - then this goes back out the gas box and under the house, over to the other side of the house. I managed to grab a picture from a neighbours house showing what they are doing:
Any advice would be appreciated

Do you mean the yellow pipe? That is the gas gas pipe itself, it’s not in a tube. I think that can’t go under buildings though, hence it’s copper pipe going under the house.To me it seems a most odd arrangement, but maybe it’s not unusual?
Is the pipe in some kind of protected duct?

Snagger says it should be track pipe - house builder says what they are doing is fine. How do I find out who is right?
Call the Gas Network operator for your area. They won't put the gas on if there is any question. The housing developer will have had to use Gas Safe Heating Engineers for the installation downstream of the meter and a competent Utility Infrastructure Provider, who are subject to checks by Lloyds Register. What's installed is unlikely to be unacceptable, but the Gas Network operator will have the final say. rossmc88 said:
Difficult to see, but on your neighbours, is that horizontal pipe going in to a black duct? I think I can see a curve that looks like the top of it, bit it might be just something in the soil.Not a gas man, but I thought gas pipes in the ground had to be run through yellow perforated ducting.

Yes that duct is how the pipe gets over the other side of the house to feed the boiler. I just thought the pipe coming up through the ground would have needed a bit more protection than copper wrapped in a single layer of black tape Not a gas man, but I thought gas pipes in the ground had to be run through yellow perforated ducting.

The ducting is often used on new builds to make it easier to lay the service pipe from the main in the street to the meter. It’s not a mandatory requirement.Not a gas man, but I thought gas pipes in the ground had to be run through yellow perforated ducting.

Can someone explain why using the yellow plastic pipe under the house is not allowed? It looks like tough stuff & it wouldn't corode like copper can.
Be grand if you got a Rat under the house gnawing on it."Why is building over a gas service pipe dangerous?
Polyethylene gas service pipes are not designed to be installed underneath or within a dwelling for the following reasons:
- where there is a wall, footing or foundation built over a polyethylene gas service pipe this causes a potential weak spot, and polyethylene pipe may not have adequate integral strength to support these loadings or any building movement that may happen over time
- polyethylene pipe is built to be used underground with an adequate amount of ground cover, where the polyethylene pipe does not have adequate ground cover this may be susceptible to damage from other external forces, corrosive chemicals or changes in temperature
- polyethylene gas pipe has no fire resistance and therefore if there was a fire the polyethylene pipe can melt at low temperature"
