[aabbcc112233]

hi

i have got yellow mdpe pipe 25mm buried in screed inside my house ,running to my fireplace and cooker. i have had 2 gas safe engineers come out to me separately with contradicting advise :

1st guy saying i cannot use this pipe inside my house and suggested to me to push 12mm copper pipe through the mdpe pipe.

2nd guy saying i can use it providing when it comes out above ground i convert it to copper.

can someone please clarify what are the regulations with burying mdpe yellow gas pipe. can i use it under ground or not.

thanks

Where's your gas meter?

 

[aabbcc112233]

gas meter is U16

sorry mate gas meter is inside the house inside the garage

Assuming the garage is at the side of the house you've got mdpe inside running to your fireplace and cooker, is that right wtf.

its a semi detached house . the garage is part of this building ie walk through the kitchen and you will come into the garage then to the front of the house. the meter is in the garage.

So the only way to get to the kitchen is through the garage then?

Is this a Joe-90 conversion of a garage block?

Whatever you shouldn't have mdpe running in your screed.
I was trying to establish that it was going to your meter.
It can't be supplying your cooker and fire, if it enters a building it should be sleeved with a metal fireproof sleeve.
It sounds dodgy enough to be a joe90 job alright.

Replace with Tracpipe, although it's not cheap it is as bendy, if not moreso, than MDPE.

Totally illegal

You can not have PVC gas pipe within your house but are you sure it is not factory sheathed copper in your screed sometimes the sheath is white sometimes yellow, if it is factory sheathed copper then you dont have a problem, it is designed to be placed in a screed
