Regs for internal condensate pipe

[AWheating]

whats the MI say?

No, I'm not Gas safe.

Oh no he didn't !

M I make no reference to a scenario where the boiler is lower than the basin.

I think (I stand to be corrected) that MI for Worcester Bosch state bottom of boiler soul be 100mm higher, this is what got me thinking.

Theoretically if the trap fails then it forms part of the flue..........

If your saying that you need to be GS to extend a condensate pipe then fair enough, but is the 3/4" overflow pipe classed as part of the flue?

 

[kirkgas]

My opinion is that the whole condensate run is part of the flue, but I can see the issue with a plumber complaint that he/she can fit a 4"x 1.25" branch better than "just" a gas engineer

It's one of them grey areas and depends on the trap in use imho.

If the trap holds the seal all well and good, but should the trap seal fail......

Condensate is part of the flue. Requires gas quals and reg.

 

[emergencyman]

Well I never knew that. It used to be the case that one had to interrupt the supply of gas. Do you have a link to an official document please?

Does it stop been part of the flue when it meets a bigger pipe? 32mm? 110mm?

 

[Whyme]

if there's waste pipes in the floor connect to one of those. hepvo's are fine for waste but not sure if condense would eat the rubber bit or what would happen with backing up waste also if that was put on to stop basin waste going into the boiler then if that happened the condense cant get out so it would have the same effect ( ie boiler filling up). under floor is best, keep it inside if poss. dont worry about the basin waste backing up.

 

[Reg Man]

As far as I am aware, anything after the condensate trap is a waste pipe not a gas fitting.

That's the question that throws everyone.
