Are you allowed to run a discharge pipe from a cylinder into a soil pipe?

[garyplumb]

I've seen a soil pipe collapsed after heating water had been discharged into it, so it's not ideal to go to the stack but can be done.

This is from a megaflow and runs strait into the soil stack next door.

 

[aqualogic7]

is there a tundish higher up forming a AA airgap

That hepvo should be vertical for unvented discharge as in g3 regs.

Really?

 

[Howsie]

Yep. And the D2 doesn't comply either.

 

[stratplus]

Yes, it can go horizontal in other applications but when used for a discharge should be vertical. I'll dig out my G3 book to be sure.

 

[stratplus]

From the Bpec manual: Hepvo "must be vertical and adjacent to the water unit"
The pipe should be polypropylene to BS5254 or BSEN1451.

That tundish contravenes regs as well. They've come out of the tundish straight to an elbow.
