Water Pressure Booster Set Required

[RogerH]

I need to purchase a packaged water booster packaged set i.e 200-250 litre tank, pump and controls to boost my mains water supply so I can run at two showwers at say 6 litres per minute at 1.5 bar. I have seem a set offerred from Pump Express (ref PED 26) but it retails at £1157.37 incl VAT & delivery but I was wondering if there were any equivalnet alternatives.

Also wanted to know any issues with this sort of equipement. My local water board (Bristol) are pessure optimising and we are down to 10litre/min at about 1.2bar - so hopeless for Combi HWS or two electric showes

Thanks for any advice

Looks a nice unit,what warrantee cover do you gat how much is a replacement pump ?If you are looking to do job yourself,probably easy install

If I was doing job ,would just make kit up with tank and n/h pump,far cheaper and you are not tied down to any particular make for any replacement stuff

imho

What does n/h stand for?

Thanks Puddle. My concerns with the DIY approach are three fold.
Firstly, the tank will be holding potable water as it will be supplying all cold water taps so what sort of tank do I need to make sure the water is does not become contaminated or develops a taste taint.
Second is the pump as this must not taint the water taste such as if a lubricating gland weeped.
The third is the pump controls as it will need to be able to server constant flows and small flows such as when you poor a glass of water.
Thanks for any advise you can provide

all standard plastic water storage tanks you buy now are sealed to prevent water contamination,with lids,and filters on open fittings
Pump would be standard,probably stewart turner negative head pump(n/h),this operates by sensing pressure in the pipework no on flow and does not have any lubricants , only other consideration is if a low level tank cut off is/will be required,probably not
imho

That sounds a much cheaper option. Not sure if I need a negative head pump. Unit will be located in my garage adjacent to Combi boiler with pump on floor so should always see – say 0.75+m of head? Any advice about how to size then pump? I want to be able to run two mixer showers at the same time (both on first floor) – would 16 litres pm at 2bar be adequate.

Thanks again

in the garage? best you fit jackets and plenty of lagging!

You could fit an accumulator in the garage.
The water pressure might be a bit higher in the middle of the night, the accumulator would store this pressure until it's needed.

Thanks Puddle, that is exactly what I am going to do using a Stuart Turner Monsoon Extra Universal pump. Hoepfully easy install as in my garage. Just need to sort out a suitable tank and accumulator. Any suggestions of a suitable supplier?

Update. Low pressure problem solved. Have fitted a Stewart Turner Universal Single 4.5bar pump, 50 gallon framed polytank and 8 gallon accumulator and all works fine with typical dynamic pressure of around 2/2.2 bar at 10/15 lpm. I did not need the accumulator but without it the pump kicked in immediately a tap was turned. With accumulator I get around 10 seconds flow before it comes in so I feel that will help with maintaining good pump life. Very happy with the solution which is in the garage.
