Hi
I am fitting a smartfit y plan to my exsisting system have done all the trv's.and now need to put in an automatic bypass valve witch will go inbetween my pump and 3 port valve.the fittings on the bypass valve are 22mm . Can I fit the return from the bypass to the 15mm return from my hot water tank? witch gos to 22mm after 6 foot.
ortherwise I would have to take up a lot of floor boards to get to 22mm return.
