It is convenient to connect a boiler 3/4" plastic condensate drain pipe
to a 110mm grey soil stack pipe. There are straps that wrap around the
stack making a tee piece with a hole cut in and 32mm pipe and the likes
connected. This is commonly available. I haven't see any on these that
connect onto a 3/4", or is it 21mm, plastic condensate pipe. Anyone
know if and where they are avialable?

TIA and happy new year to you all

Adaptors are available, you could use a strap on solvent boss for a larger
size of pipe then there are solvent adaptors to get you down to the right
size. You may also be able to get a direct rubber adaptor which would
have the benefit of being easy to dismantle in case of problems.

Sorry not to give full details but am in a bit of a rush.

Thx, and you

Yes, you can get solvent weld adaptors that will take you from the
21.5mm overflow size to 32 or 40mm waste size.

www.bes.ltd.uk parts 11939 or 11940


or from plumbers merchants - I think OSMA makes them.

Don't forget that if you do this, you need to have some form of trap
between the boiler and the soil pipe.

Thanks. Why would I need a trap teeing into the 110mm grey stack pipe
when I don't need one teeing into any other drain pipe?

All connections to a soil stack need a trap.
However, there's very likely to be one in the boiler anyway,
as it's also required to stop the flue gasses leaving the
boiler via the condensate pipe. You might want to include
an air admitance valve in the pipework though, so that no
pressure changes in the drain can suck the boiler's trap dry.

Also would suggest not routing the 22mm pipework outdoors.
My boiler requires any outdoor condensate pipework to be at
least 32mm, to reduce chance it will block with ice in cold
temperatures.
