condensate overflow pipe

[goatib]

I often see condensate pipes joined to rainwater downpipes so it must be OK for them to discharge into the same drain.

So, would it be OK for a condensate pipe to discharge above a running gutter outlet (i.e directly above the downpipe) instead of forming a union lower down? The gutter is plastic, not metal.

We have a porch under the egress point of the boiler's condensate pipe and it'd save an unsightly pipe run if I could let it discharge into the porch's downpipe.

Just asking

Condensate is mildly acidic, about the same as Coke, so it should not go in dedicated rainwater drains. It should go with "normal" waste water.
The requirements are listed in the M.I. of your boiler.

Yes it's OK. If it's a dribbler though (they vary) freezing can be a big problem..
If it's into a soakaway it 's supposed to have a thing in the way with lime crystals to neutralise it. Like about 1% of them do...

Condensate from boilers is not allowed to discharge into a rainwater system although an awful lot do

If you put it into a hopper or gutter (not allowed) instead of a hole through the side of the drain pipe(not allowed), when we get snow the hpper/gutter will fill with snow/ ice and you pipe will become blocked, and your boiler will shut down

I know it's acidic.

The downpipe from the porch AND the current condensate pipe both discharge into the kitchen's foul water drain. It's because I have three pipes on the front of the house all going to the same drain that I asked whether I could let the condensate discharge higher up into the downpipe thus negating one of the unsightly pipe runs.

So, this would be OK then as the water from the kitchen is "normal" waste water?

OK, thanks. As above, really. The intent was to place the condensate pipe an inch or so down the vertical downpipe. The fall is about 7ft from that point to the drain.

Although "not allowed" you see it done in loads of places but no-one has it quite like I'm asking about.

The current route takes it all the way down with the rainwater downpipe where both discharge into the kitchen drain.

Thanks anyway.

In 2 years I've yet to see anything come out of this pipe, I'm not there all the time so it probably waits for me to stop looking before having a quick burst.

No problems in your case. Just make sure the condensate pipe terminates over the gutter and doesn't rest in it.
