gas pipe in cement floor.

[that bloke.]

in order for me to be able to figure out where to site my boiler i obviously need to be able to get gas to it. Calor have just installed an lpg tank in the garden and brought the pipe work to the house terminating on an out side wall. My understanding is that it needs to be 22mil pipe , wrapped in denso tape , 75 mil down below floor level and 25 mil away from other services. Is this correct?

who told you that, and who is installing gas pipe??

i read that on tinternet , all i am doing is digging up the floor to lay the pipe providing i can work out where it has to go , it will be a gas safe person putting in all the gas work.

best not to lay pipe in concrete if you can help it, easier to route behind cabinets. If in concrete, duct it, or lay using plastic coated pipe.
If your boilers on an outside wall, run the supply to that position, easier in the long run.

cheers op , unfortunately my boiler position has been moved to another room , its around 3 meters away from where it should have been although all this is still just speculation as i may not have to move it at all , hopefully.
i have now read that the pipe needs to have 25 mil of cement/screed ontop of it , if this is true then i might not have to breech my dpc , any thoughts on this depth issue?
coated pipe sounds better as i may not have to dig out too much floor for it , i will see what the gas safety plumber says on the day , obviously any solder joints such as the 90 bend below the riser to the boiler for example will be wrapped in tape. the last time i put in a gas pipe i was under supervision (still a mate at the time)and ran a 3-4 meter run of 22mil through a concrete floor and wrapped this in denzo tape , my boss seemed to think it would be ok but i dont think we had any coated pipe anyway.
is it only electrical cables/plugs/appliances etc i need to worry about or are there rules about running gas near water pipes as well?

lol makes you laugh one minute 'im only doing the digging'

next minute your on about wrapping soldered joints.

each to there own - but why try and pull the wool over our eyes haha

 

[that bloke.]

why would i try and pull wool over your eyes? i am trying to figure out the depth so i can ready it for the plumber , if i have to go down through the dpc id like to know about it well in advance , what makes me laugh is some gas fitters unwillingness to give out any info to help a person save a few quid by doing as much of the work them selves as they can.
most plumbers would be happy to have the trench dug out for them , unless they were skint and really needed the work.

Best thing to do is ask the GSR engineer that will be doing the work what you can do for him in preparation, to save you money. He'll be resposible for all the pipework so he'll need to see it going in....

your right of course , il give him a buzz and see what he says. cheers fella.

 

[migoplumber]

thats definetly the best bet - and yes he will be over the moon to have it dug out for him !!

 

[so-solar]

every single new build i have first fixed has the gas carcass in the screed! just wondered where oldplumber got the info on not laying it in the concrete?

 

[that bloke.]

he did say it was best not to , he didnt say it couldnt be done. i tend to agree with him , new builds usually have pipework hidden to keep it all looking nice and clean.

Use plastic couted gas pipe at least 22mm depending how far away tank is (your gs plumber will size for you)
In screed is fine the 25mm is away from any electicl wireing and 125mm from any fuse box
Hope this helps

I would also want to know the cost of corgi registered plumber for first fix please.

 

[Gray0689]

Just get a gs plumber to come and do it different areas diff prices it's not going to break the bank
