Condensate waste pipe slightly larger than 21.5/22mm?!

[tom foster]

I'm trying to join two pieces of condensate waste pipe from a combi boiler, but it seems like the pipe that has been used is slightly thicker than the 21.5/22mm stuff that's standard.

Hence, I can't seem to find anything that will allow me to join the pieces together - all I want is a straight-through coupler (preferably pushfit). Does anyone have any suggestions, as I'm well and truly stumped!

McAlpine Commpression Coupling they normally fit anything but on some boilers I have used a Wasshing machine flexible waste extension, the rubber push fit normally fits the condensate spiggot (Especially Remeha)
I then fit a washing machine waste upstand to take the condensate to drain (which is OK if you have the room to do it!)

by far the easiest way to do this, trying to find a match for overflow pipe is trickier than any other pipes, it can be a nightmare and usually means ripping one half right out,

Thanks for the advice - any idea where I might be able to pick up a McApline 22mm compression coupling? I haven't seen anything like that anywhere I've looked, only the standard ones for 32mm and 40mm pipes.

Any 'proper' plumbers merchants will have them, feel free to join the queue on a Saturday morning to ask for them though.

They all seem to be on godforsaken trading estates, with only a burger van for company.....

It could be Marley overflow poxy b`stard sized stuff - but you can get adapters for it

Heat one end of the overflow with an electric paint stripper like a high powered hair dryer then carefully push the other end into the heated pipe to form a socket when cool twist to remove & solvent weld in place job done

For the benefit of anyone who might come across this thread in future with a similar problem, the adapter I needed was a McAlpine R1M. I had a bugger of a job getting hold of one (none of the plumbers' merchants near me had one in stock), but it did the job perfectly.
