Hi hope you are well.
I have a gravity fed hot and cold. Hot water cylinder is on ground floor. Cold tank is in loft. I have 2 showers on 1st floor. One is pumped by a pump in the loft. Other is pumped by pump in shower itself. The latter is noisy and I want to replace it. But pressure at the baths upstairs is also not great.
i think most of the downstairs cols is from the mains , but most if not all of the upstairs cold is from the cold water tank tank.
1) can I use whole house pump and the existing shower pump in series? the shower pump is not just a pump, it is a mixer as well so i cant easily just get rid of it.
2) will whole house pump give same pressure as dedicated shower pumps (assuming i can find somewhere upstairs, probably in the loft , where cold from tank and hot are accessible)
3) some of our pipework is 15mm is this a problem
4) is "shower power booster" a match for stuart turner 3 bar whole house?
Thanks for your time
