whole house booster pump

[SafeGasInstall]

I have a job where I fitted a single impeller 3 bar stuart turner pump to boost whole house water but unfortunately customer is not happy as pump struggles to deliver enough flow and pressure to feed kitchen sink mixer and wash hand basin at the same time , let alone the new shower .
Has anyone ever done a breaker tank and booster pump to WHOLE HOUSE ? If yes what pump can you recommend me ?

I have fitted a 100 galon cold water storage tank so could feed the right pump .

It's a simple enough job Stan but I'm surprised the 3bar isn't with a sink and basin. Are you sure there aren't other problems before you go down this route? Such as cheap SV's or twisted flexis?

Pump delivers only 18L of water but pressure is really bad so from kitchen mice I get 18L flow of hot and cold but then if I open wash hand basin flow drops dramaticaly
customer had really high expectation and want to be able to run all taps in the house + dishwasher and washing mashine without a drop of flow

I fitted 100 gallon tank in the loft and new WB 34 CDI combi on the ground floor bathroom , pump is feed from a dedicated 22mm supply and pump is next to boiler .
Boiler delivers 12L of hot water at 65-70 degrees but if open another tap flow glorious down
just to explain that pump will also feed all cold water outlets : 1 shower + wash hand basin + kitchen + another wash hand basin + dishwasher + washing mashine and softener installed in later stage

If he want's to run every tap then he'll need a complete re-pipe.

i have done 1st fix on the new bathroom where they going to have a rain water head 400x400 and have piped it up 15mm !? wash hand basin 15mm and new pipe work to kitchen will be 15 mm too . there is 34 cdi combi that delivers 12L of hot water at 65 degrees

 

[Howsie]

Who worked out the pipe sizes based on the water demands at the outlets?

i have i have just been reading on the Stuart turner web site and realised that the pump i have selected for the job is only for a single shower what a plonker I am .......
I dont know what the demands will be in L/min tbh .....
All I know is that there will be a shower head 400/400

Hi Guys
Had a similar thought in my house some years ago. What you need is a pump that is operated from a pressure switch not a flow switch. I used a Grundfos JetPaq. These are no longer available but Grundfos do offer modern alternatives.
