How come you have got a piece of pipe not connected to anything.
Longterm surely you would be better with a 40/40. I use a similar RO to you bought from Doug but my tap tds ranges between 44-75ppm

I suggest that you take a pure water sample from each pure outlet and measure the tds of each membrane.
You still need to measure your pure to waste ratio when the unit is processing water.
There was a cleaner once who shut his waste tap off completely and over a short period of time destroyed his membranes. At you tap water tds you need to have a ratio of around 60% waste to 40% pure.

Thanks spruce I will get there in the end but how do I take a sample from each pure outlet ? Very very new to this so please give me time cheers .

The pure pipes from each membrane join together with a T piece and head off to your di vessel. Just remove the pipe from the T piece, catch some water from the pipe in the cap from your tds meter and measure the tds. Then do the same from the other membrane.
Hi spruce just checked pure and waste it is about 55 waste & 44 pure

OK. At least you are running water to waste not like the other fellow.
You need now to take a sample from each membrane to see what its doing.
Odds are you need new membranes. When did you last change your prefilters. Its important that they are changed regularly as the carbon block is the one that removes chlorine. Chlorine destroys membranes.

Hi spruce thanks , I've had wfp system about 7 months and never changed filters etc what's the cost for new membranes do you know ? I will take samples from membranes in a bit ! Thanks soooo much for your help , also do you think it would be better to go 4040 ?

DAQUA - Suppliers of Axeon Reverse Osomosis Membranes such as HF5 4040, HF4 4040, 150 GPD membranes
either
Axeon 150gpd RO membrane
or
Spectrum 150gpd RO membrane
Prefilters
Fiberdyne carbon block
10" Fibredyne CFB PLUS Sediment/Carbon Pre-Filter - Sediment & Carbon Filters - Water Treatment - Pure Water Systems - All Products Gardiner Pole Systems
sediment

I personally don't like the PENTEK Chlorplus-10 Filter Daqua sells as they are a 1 micron filter. The sediment filter is 5 micron so bits between 5 and 1 micron will get through the sediment filter but get blocked by the carbon block filter. I found ours got blocked long before its service life was achieved so was a waste of money for us. But our water is very heavy with sediment at times. It might work alright with you though.
Gardiners only do 100gpd membranes and you want the quickest ones you can get, hence the reason for linking you with Daqua.
Yes you are better with a faster producing 4040 but you need to get your r/o sorted before you join the big league. 4040 membranes are expensive.
Ordinary cheap carbon block prefilters only have a service life of 10,000 liters according to the manufacturers. This 10,000 liters includes both pure and waste water consumption.
If you are using 350 liters a day of pure then you will be using slightly more than double with producing that. So each day you will be using about 800/850 liters. With a cheap carbon prefilter you would need to change them every 11 working days.

We all started off learning from others and making our own mistakes.
You can improve your water production a little by adding another housing and membrane. That's a cheap upgrade that will get you 50% more water. Whilst that sounds a lot, its still a small amount when compared to our 4040 that produces pure at 2lpm.
We found that a 450GPD r/o was sufficient to keep 2 of us in water with a little planning and processing water into a 1000 liter IBC tank, transferring to the van as we needed it. It took us around 28 hours to fill an IBC tank in summer so once you get on top of it you will have plenty on your own.
