track pipe in concrete

[kozak1968]

I've also ran the water main under the celotex. But not in mdpe. Can't see a problem as long as the gas and water are apart. The main would need to be insulated.

for trac pipe - run it ontop of the concrete, band it down and cut and lay insulation on top for underfloor.

as for water main change to pipe in pipe speedfit style or maybe even make your own insulated pipe in pipe with some speedfit, ducting and lagging.

What did you use for water just some plastic pipe work like polyplumb ? What insulation did you use 12mm ?

 

[Ermintrude]

It's in celotex so just 22mm?

 

[SafeGasInstall]

So run them on top of the cement bace under the 100mm insulation and then ufh and screed ?

Cheers every one !

 

[Ermintrude]

Yes but sleeve gas so insulation voids don't fill up!!

 

[Reg Man]

Or fill the void with sand.

If I run a 28mm copper in a 1" 1/4 will that be ok ?

Trac pipe classed as pipe in pipe so along as both ends are above the finished floor it can vent itself if there is a leak.
