Brink Flair condensate drain

[jayc89]

My Brink Flair 325 has a 32mm condensation drain connector, I only ran a 21.5mm drain up for it (before I knew which unit I would end up)... What's the best way to reduce the 32mm Brink connection down to a 21.5mm solvent weld one?

Connect a dry drain trap below to the 32mm, then do a 32 to 21.5 solvent adapter to the drain trap compression joint.

Turns out 32mm in the user manual != 32mm compression fitting. 

 

Anyone know what I should be using for a Brink Flair 325 drain connection?

 

[jayc89]

Anyone know what size this should be?

 

I'll take it into my local plumbers merchants at the weekend and see if they can help. Not sure they're much cop if you're not asking about a 22mm compression bit though...

According to the manual the outlet on the siphon is 32mm OD and they suggest DN 32 HT

 

You need something like this to get from 32mm OD [German Spec] to 32mm ID [34mm ish OD] UK Spec.

Best to take the syphon with you - it looks like it comes off.

The Euro sizings will be where I went wrong - thanks!

It fits but there’s a notch out the back of the drain itself. Is that just an air break? Worried any potentially back flow of waste could end up all over my loft… presumably a waterless trap helps avoid that?
