New boiler and condensate pipe

An occasional drip seems very common and IMHO no cause for concern.

Except that it's acidic and not the sort of thing that should go just 'anywhere.'

When I last looked, the condensate either had to go into a drain or into its own purpose-built soakaway, which is basically a drained plastic container filled with limestone chips to neutralise it.

As said above its never been acceptable to terminate a condense on to the ground. It has to go into a foul drain or purposely built soak away.

Condensate from a boiler is only mildly acidic, i.e. no more acidic than condensate which is discharged from a car exhaust. I am told boiler condensate has a pH of circa 4.5 isn't particularly acidic. Vinegar has a pH of up to 2.4 (i.e. much more acidic). However that is all beside the point.

My point is there are many many flats where boilers have been installed like mine.

Boiler Discharge Flue


Boiler Discharge Pipe


Depending on the boiler type chosen and the location in the property, this arrangement may not be suitable and I would suggest OP seeks advice from the boiler manufacturer.

Condensate running over concrete will eat away at it. It certainly has eaten away at my garage floor when I diverted it to avoid the frozen pipe problem.

Whatever you say, all those people who chose non condensing boilers must be wrong.




Let's blame it on the Russians :rotfl:

You can't choose a non condensing boiler, it's the law. There are very special exemptions to that but it is rare, very rare.


That's not condensate pipes, they are pressure relief pipes, condensate must be in plastic and can't be allowed to just drip into the ground. A badly fitted flue that doesn't fall back to the boiler properly is a badly installed flue not a feature.

That was a joke dude :easter:
Just so we are clear, all those boilers must be badly fitted and illegal :eek:

Just so we are all clear, you are looking at the wrong pipe, the pipe that turns back to the wall is not the condense pipe it is the pipe from the pressure relief valve & should not drip

If Missile has a close look at her boiler set she / he will find the INTERNAL condensate pipe somewhere.........

Have had my condensate pipe on outside for the last 9 yrs never froze, but with this beast from the east, froze it. This weather was exceptional as my down pies were filling up with snow the end of the pipe was freezing and sticking to down pipe and this was backing up the rest of pipe. Even when we took it out of the down pipe the drip was freezing before it dropped. It did not help when daughter took a late bath and this froze the down pipe at height of the beast. We are now putting a big pipe over end so it wont fill up with snow and drip won't freeze. I hope we don't get it that bad again.
