Hi,
I have the not uncommon problem with a new bathroom installation of poor flow of hot water from the mixer new taps on the basin and bath.
I have mains pressure cold water throughout the house and I'm considering fitting a pump (RGP 80) to the hot water supply.
As the hot water pipework is 22mm I've gone with the RGP 80 as this comes with 22mm couplers.
My concern is that I don't want to overwhelm the cold water by fitting this 2.4 bar pump. The mains pressure is OK but not brilliant.
My question is, would it be wrong to fit a pressure relief valve immediately after the pump, so I can limit the boost from the pump?
or
Should I go with the RGP 50 which is lower power (1.3 bar I think), has 15mm couplers and so would require reducers but likely wouldn't require the pressure relief valve?
The hot pressure downstairs is OK, it's just upstairs in the new bathroom, and soon to be new en suite, that this problem exists.
I do intend to raise the cold water tank in the loft in due course, but this would only be by a couple of feet and won't dramatically affect the hot water flow.
I look forward to receiving your comments.
Thanks in advance.
