Water softener and low water pressure

[amytomsam]

Hi all...I have a Liff 2000 series water softener. The mains water pressure fluctuates outside (lower end) throughout the day of it's set operating pressure which is between 1.7 to 5 bar.
I know that the water company must provide me with at least 1 bar by law and have asked several times for a water pressure test but am losing the will to live with them....anyway, the upshot is that when I have a couple of appliances on together, such as the washing machine and the dishwasher, the softener slowly fills with water as the pressure drops too low to allow the non return valves to work correctly....well, that's what I think is happening anyway!
Am I going to have to fit a booster pump after the stop cock in the house or is there an alternative solution?

you can't it's not allowed

oddly enough it is in the states

OK....In my Liff manual it states...
"Problem....water level in brine cabinet reaches overflow.
Solution: Fit a pressure reducing valve or booster pump as required."

How can I do that then if it is illegal?

ok you can't pump directly off the main
if you use a pump you will need a break tank as well to store the water

bit pricey tho

OMG!!! That looks expensive!.....gonna check the actual pressures and record them and plan A is to see if I can get the water company to boost my pressure into the property from the mains first!...been next door and that seems to have cured their problems.
