Condensate drain to flat roof - right or wrong?

[Goose123]

Hi,

I had a worcester condensing boiler fitted a couple of months ago. It was moved to a new location in the bathroom and the recent cold weather showed that it drains via a copper pipe onto the flat roof of the kitchen (which sticks out below the bathroom).

This doesn't seem right to me - acidic condensate on a flat roof. Can somebody point me to the section of the regs that says that this is wrong so I have something to go back to the installers with? I don't want them to say "it's normal sir".

Thanks,

Goose

Shouldn't be in copper for a start

you sure its the condensate pipe and not the "blow off pipe". As for the regs you ll find info in your manufactures handbook for the boiler, you ll also find out it should be run in plastic, to a soil waste drain etc etc

I agree with yellabelly the copper pipe is prob pressure relief valve not condense

But water comes out of it every time the boiler runs. It's got over 2 bar of pressure - could that be the cause of the overflow? If so, should I leave it to get down to 1 bar in the hope it all sorts itself out?

Sounds like the prv is opening,get your installers back

Nothing wrong in terminating onto a flat roof is the area is sufficient to dilute the condense and it runs into plastic guttering

Nonsense it must run in a pipe all the way to a suitable drain or termination point and a flat roof is not a drain
