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.
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...
