Post by: CLEANGLASSUK on December 10, 2008, 09:43:33 pm

As long as you have sufficient flow rate. You would need about 20lpm flow rate.

You would achieve a lot more with a booster pump.

Your pressure is really quite low. You would probably double production and reduce TDS out as well.

Your water pressure must be very good.

A call to June at Gapswater would be a good thing though. If anyone knows her stuff on RO systems it is her.

I often recommend people to Gapswater. Great products at very good prices with superb back up.

I have 1 4040 with a 24/7 booster pump from Gardiners and would easily fill a 1000ltr tank in 4 hours at around 6tds.

I have 1 4040 with the booster pump that Andrew has posted, takes around 3.5 - 4 hours to fill 1000 litres.

I have a twin 4040 on a grundfos booster pump

it will produce around 600ltrs and hour @ 100psi.
