any help? as in  sick of my 450 gpd had new filters and membranes only 3 months and water production is pants!!!  tds from tap is 84 water pressure in is 55 psi water production is 1 ltr in 4 minutes thats over 5 hours for 80 ltrs  with tds of 2 coming out    so  in the market for guaranteed water for either a 40 40 from gaps with the pressure gauges and pre filters this one  http://gapswater.co.uk/acatalog/copy_of_copy_of_Reverse_osmosis_kits.html

or gardiners one   http://www.gardinerpolesystems.co.uk/acatalog/-EZ-Pure--Commercial-RO-HF5---Kit1-EZ_PURE_RO_KIT1_HF5.html

anyone have experiences of either and pros/cons ....many thanks from a long time puzzled wfper

I got one from gaps 6 months ago  hf5 with fibredyne filter, takes 4 1/2 hrs to fill my 500l tank with only 30 psi, water Is about 350ppm in and 17 ppm out.

With your  water pressure you would get better results.

[Michael Peterson]

sounds like a good system

use a booster pump, my 450gpd produces 60l per hour no problem,

I got the Gaps HF4 4040 with fibredyne filter recently (black filter housing with 2 gauges), and Clarke cbm 240e booster pump.
Tds in= 240ppm out= 008ppm
Produces about 3 ltrs of pure per minute.
ps. I did consider the EZ-Pure RO but decided to go with the 4040 because they are similar price and the 4040 will produce water faster than the 21" EZ-Pure membrane.

A 450 GPD processing into an IBC tank should be more than sufficient for your daily requirements. Our water pressure was 50 psi and we managed with 2 of us working full time.

As per Combat1's thread, check your waste to pure ratio. If you are sending too much water to waste, then production of pure will be poor. With Combat1 his problem was with his flow restrictor.

its a right dilema infact so much so filters and membranes are slowing down up here in the north for some strange reason after around 3 months , a few of us have all had 450 gpd from different suppliers and changed the pre filters every 4 weeks as we all use around 2000 lts a week each, two pals have  given up after spending £££ on membranes in 5 months and ive spent the same and in the end thats the poor results im getting, even getting the expensive pre and good membranes from ro man. nothings changed water to waste ratio is spot on,pressure spot on and a impressive tds from the tap should make water forever but after 8 years wfp we are baffled

Talk to the nice Lady at Gaps. She will tell you what filter for what pressure etc. My new filter is producing 500lts in about 2.5hrs with 75 psi and in the tank at 002 tds.
