Ive been asked to remedy the low water pressure at the x8 electric shower outlets at a care home.
Currently its an open vented system, with heat only boiler with CWS and F and E tank.
It appears all the showers are run from the gravity feed and a few off the cold mains? Its hard to know given the extensive refurbishment and pipes in newly plastered walls.
Im going down to site today to take standing pressures.
I will take dynamic pressures with x7 outlets open then x2 outlets.
Then I will take flow rates at outside tap, then with x2-7 cold outlets open at once?
Once I have established these readings, do I need anymore information from site before installing a mains boost cold water pump?
Will a mains cold water mains boost pump be adequate to run x8 electric showers at once?
Or do I need a separate CWS supply to pump from?
Is there a better soloution to running x8 electric showers from the cold mains?
Given its a 1930s mansion, upgrading the cold mains to 25mm MDPE? Or bigger?
Would it be best to rip out all the showers and install thermostatic showers and run a new unvented indirect system with system boiler S plan if readings for flow rate and pressure are within range? Then an accumulator or mains boost pump?
Or shall we keep x3 electric showers from cold mains feed and install x5 thermostatic showers?
Its a lot of questions I know! We just want to ensure the vulnerable residents can shower adequately.
Any other ideas appreciated!
Ho ho ho.....its time to work while all others feast
