hi, have a indirect hot water cylinder with hot and cold both fed from a 80 gallon cold water tank.
Have recently fitted a thermostatic bath shower mixer tap as didn't want to chase walls/remove tiles to fit a dedicated shower. Both has poor flow plus the flow to basin tap is generally poor which I'm guessing is due to a gravity fed system.
Planning on fitting a salamander 2bar twin negative head booster pump in airing cupboard.
I want it to boost all outlets in my house.
Would it be ok to fit a Surrey flange on the hot and run 22mm to pump as the hot suppy l, and where the old hot draw off on top of the cylinder tees off for the hot supplies cap that part of then connect the outlet of the boosted hot back into the hot water circuit?
For the cold it is ok the find the cold down services from the cold water tank cut into it and fit an elbow into the pump and again fit the boosted cold back into the other side of the cold pipework? Wouldn't have thought I'd need a dedicated suppy as I'm boosting all outlets and not just the shower?
Do I need to fit non return valves on the other side of the pump or will they all ready be built into the pump?
And finally, is it worth fitting a AAV on the inlet to both hot and cold supplies feeding pump to help with any air issues?
Thanks in advance for your help/advice.
My skill set for plumbing is pretty good, so far I've fitted my own bathroom and replaced hot water cylinder in my old house.
