Come to think of it so would the pre filters be gone if you were getting 150 after them.

Yes there is a sediment filter and a carbon filter before the 4040 RO. It looks like I will have to replace the lot just so it's all new

Thanks again for all the help

Hi there again.
So I have managed to do what has been suggested. Did 50/50 and 60/40 ratios but still coming out with the same result about 157 after RO

P&F you got it. Ok I know Spruce put a link to a company for a new RO filter. Any others out there that I maybe have not looked at. Any comments or Spectrum filters. Any advice on how they go into the stainless steel housing. Watched Squeaky clean Dave. That was the white canister you can get. Thanks Aiden

My round is still small and depend on how many bungalows I also have. It could be between 300 and400.

Spectrum sediment filter is ok.
Service life on a Spectrum carbon block is poor for the price - Fiberdyne is a little more expensive but has a much longer service life.

I have no experience with Spectrum 4040 membranes but I would still go for Axeon HF5 even although they are more expensive.

Generally speaking its easy to get swayed on price. There are cheap Chinese knockoffs in the market for 1/2 the price but not suitable for window cleaners.

We need the most efficient membrane that will take the most impurities out of the water. If we use a less efficient one, the additional cost of resin to remove those remaining particles will negate the initial cost of buying a cheap membrane.

You canít negotiate with gravity

The older I get the better I was ;)

So I took the advice and purchased all 3 filters. Axeon HF5 and the other 2 suggested.
My TDS has come down from 155 to 97 before the DI. My tap pressure is 40 psi but the spot where I am getting 97 is at 22psi. Either side of that it creeps up. Going on threads and videos I have watched, this is too low to produce a lower TDS. Any advice will be great.

A booster pump... If your producing the water at home, dont forget when you've got things like washing machines going, showers,  etc this will lower your pressure even more while there on. Ideally you want the pressure around 80psi to have your membrane working at its best a booster pump will do this.
Also what you have your waste to pure ratio set will affect your tds readings. If your mains input is around 260ppm i would personally set it at around 60 -40 pure to waste as a starting point and go from there.
