    So yesterday I met a fellow windy at the suppliers buying his first off the shelf WFP system.

    As Adam stacked up the bits the look of 'what have I bought' kicked in. So I said bring it on over and I'll help out so we put it together today which brings me to my question.......

    His RO has a built in pressure gauge and when I connected it to my tap the pressure gauge said 30 PSI.

    Now I don't really understand the water pressure and it fills my 500L in about 5-6 hours through my 20" RO which is OK with me but would I benefit from a booster pump and if so why? What Ideally should water pressure be to get optimum production?

    Thanks for the helpful answers in advance.

    I think 70/80 psi is the recommended pressure for best use

    Perhaps this is the best video explanation.

    Mine is around 40 psi which suits me has I have x3 1000 ibc's so one week running one week off, I have a pump but I don't use it but I'd guess it would do an extra 200-250 litres a day with it on

    It depends on the membrane inside the housing mate, do you know what type of 4021 you have ? A hf4 4021 technically should be ran at no less than 100 psi and a hf5 no less than 80, although it will work under that but won't be covered under warranty by the manufacturer, we have 30 psi at the warehouse and a 4040 brand new out the box brings our 258 tds down to 24 normally with the booster pump we double fill time and the tds is 6 going into resin, and cheers for helping him ;)

    Don't mention it, I was better paid for it than Sonny! I got six shiny green bottles full of Peroni for my effort! :))

    I would have thought due to the volume of water coming out the tap that I had good pressure but guess not, guess it's same as the pump conversation, pressure and flow are not one and the same
