Moving gas pipe

[bassmonster]

hi all,
i've been asked to relocate a gas pipe in a kitchen. at the moment it's running along the side of the walls but it now the customer wants it buried under the floor. it's a concrete floor ( i won't be doing any of the breaking or digging). :smart:

If I remember correctly, the pipe has to be around 375 underground if pipe is outside...does the same apply indoors? Also what is best method of protecting the pipe?

Indoors it just has to be X amount under the top of the concrete I think its like 40mm minimum but I'm most likely wrong

Sounds like a job for Tracpipe!"

Wrap it in hairfelt to protect from the cement

Customer will not cough up

Wrap it in hairfelt to protect from the cement

will denso tape be OK seeing as i've got some over from another job?

Denso will be fine. Hair felt is not suitable IMO as cement can seep through it and attack the copper.

Off the top of my head needs a minimum of 25mm covering indoors.

I bet when there is a problem - if there is a problem, that the customer will dispute the fact.

If ****e hits the fan down the track due to a problem, you will be the one and only person explaining the situation to the insurance company's lawyers, over taking short cuts to save the customer money.

Stand up for yourself and tell the customer how the job is to be done.
If they can't afford to have the job done properly - then don't do it.

Can you afford to liquidate your assets to pay for rectifications / repairs to the customers property, if your insurance won't cover you, due to non complient works?

Copper wrapped in denso (or run in a duct) under screed is perfectly compliant in the UK, Oz. Tracpipe is the premium option but not the only permissible option.

As long as bassmonster wraps the pipe properly and achieves the correct depth, he'll have no case to answer.

You need 50mm of covering concrete over the pipe I think.

I've never checked really because I try to get 100mm covering or more so theres no chance of a nail or screw going through it

concrete will eat through hair felt lagging, ive replaced alot of copper before where its been in hair felt lagging and concreted over and eventually pinholed through.

25mm cover in a screed.
You can wrap it with pvc tape if you like (preferably yellow)
