Boiler condensate pipe advice please
Now I realise this is a car forum but my boiler is in my house which is next to my garage which has a kit car in it so there's the link :p
lol
Anyway, fitting my bathroom now and thought it would be prudent to fit a condense pipe from the airing cupboard (where the combi lives) into the waste
in the bathroom so when I finally have to get a new boiler (non condensing at the moment) it will be in place.
I can't get a good fall so it looks like I'll need a pump with this future boiler, question is, what size pipe should I fit? It'll
go just after the sink connection in the run so it will get washed down regularly, all the pipe work is indoors under 'floor.
Cheers

You cant really pump condensation, as its a very small amount of water thats created. Aany pump would just be tuning in air most of the time.
Cann you not just drill an overflow to outside and let it drip on part of the garden or link to a RWP?

you can get pumps for boiler condensate,in your case it seems that you should be able to tee it into either the bath or basin waste,both of which are
preferable to going outside with a condensate at first floor level due to freezing risks.
Do not allow for it to drip into the garden this is illegal.

Yeah you can get dedicated condensate pumps especially for it, my mother in law has one, it just drains into a sump and pumps out at a certain level.
Some of these boilers give out a lot of condensate by all accounts.
There are rules re discharging outside as its acidic so either needs a neutraliser or to drain into a limestone soak away. It can however go into
household waste downstream of regularly used appliances which also avoids the problem of it freezing up and shutting the boiler down.
Just looking for a one size fits all solution for the pipe into the airing cupboard really.

20 mm solvent weldpipe into an 1 1/2 tee with a reducer or 1 1/4 tee.

Nice! Thanking you.
Just got the floor up, can achieve a fall of about 50mm per metre so looks like I can avoid a pump too
Cheers!

Overflow pipes the stuff you need think its 21.5 mm use the glued stuff and proper glue not pushfit type
If you install the pipe ready make sure you put a trap on or plug the end till its ready to use or it'll pong

Aspen condensate pumps use a peristaltic pump so it doesn't matter to them if they're pumping water or air.
Cheap enough on eBay too.
