    I have a customer who wants to have a new combi fitted in their basement.

    Have worked out a way to route the flue and can use a saniflo pump for the condensate.

    Am just wondering if there's any way to get around the PRV having to have a continuous fall?

    I would have asked this in the combustion chamber, but am waiting for my approval for the site to be granted. Am Gas Safe registered, before anyone posts a reply saying "get a registered guy in to do it".

    Many thanks,

    Dan

    Drop it into the condensate pump. Check with Saniflo that it is OK with their pump; use another make if not.

    Thanks guys,

    Have opted for a Baxi & their combined PRV & condensate pump.
    Pricey piece of kit but only one I found that specifically said that it's designed to do both.

    MM might have a problem answering that unless the MI have now been written!

    Perhaps it could be passed through a fanmy trap and then pipes in 32 mm plastic to the pump?

    3 bar prv on boiler plumbed into the return pipe. 22mm pipe teed off the return rising vertically until height of the flue then an external prv at 2.5 bar attached to this 22mm pipe then 15mm discharge ran off as normal. Baxi approved this solution and sold me the 2.5 bar prv. Check with your boiler manufacturer to ask if you could do the same.
