how to do it?
2007-10-26 12:54:27 · update #1
The sleeve is NOT to make the line easier to replace. It is simply to keep leaking gas from building up under the slab. Leaking gas will travel up the sleeve and and into the open air, not under the slab. If a lot of gas builds up under your slab, leaks through and ignites, you will have a lot bigger problem then a little digging.
Codes like this are not usually put into effect just to make future repairs easier, they are for safety.
Good Luck

the Queen has it right. Yes, it must be sleeved. Were it not sleeved and it developed a leak it would leave you with one choice for repair; having a plumber tunnel under the slab and replace it. ($$$By no means cheap$$$).

If it is sleeved then you will be able to change it out if there should be a leak under the slab...

It is not recommended to run gaspipe under the concrete slab by safety codes .
Buried gas puipes need markers along its route for easy identification .
while crossing road/railways under ground , protection pipe sleeves with venting pipies at both end of the enclosing pipe, is design rule.
