Main Combi 30 HE Leaking pump

[lexx]

Hi,
I have a MAIN Combi 30 HE boiler. The pump housing has a leak from the return pipe connection,top screw. I want to replace the o-rings but cannot find any info on the part numbers for the o-rings?
Can anybody give me the correct part numbers.
Cheers.

Thanks for the reply.
I had a closer look, the boiler is a MAIN COMBI 30 HE.
The boiler manufacture address on the boiler case is Baxi potterton.

247429 is what you need.

They usually only leak tho if the system is dirty.......if so get it cleaned.
