I am still running a RO-Man type of RO (upgraded to three chambers on the top) system which I have had for about ten years. But because I also feed Dan the Man his water I find it struggles to supply all our needs especially after the membranes and filters start to get clogged.
So I really want to uprate the capacity of my water output. Unlike most I also like to bring my water to 000TDS (letting it rise to about 005 max) before I pump it to the van.
What should I get?
I use about 1200 litres of pure water a week and Dan uses about the same so 2400 in all.
What should I get? I'd rather have more than less so about 3000 plus per week is about right.

Where do you want to be in the next year or so ?
Ultimately it's the 4040 route - quick, high volume, brings my tds down from mid 300's to 004
I loved my Merlin, it served me well, I only sold it after 4 years because a 4040 system was in the van I brought, down side is water usage is slightly higher, but I boosted mine, and to be honest I never noticed a drop in usage when going 4040.
You can now get 2020's but have no knowledge of production rates etc...

With a 4040 it's future proof, I require 2k of pure per day - this keeps up ( although it's a bit close some days ) that's storage issues not production

I've got 2650L of static storage capacity.
So how much is everything I need for a 4040? Where would you buy it?

you could buy it from purefreedom as a plug and play system wouldnt be my 1st choice but all set up and ready to go
gaps water
daqua
would be my 1st choice

I got my 4040 from gaps water around 2010. The nice lady there (June?) even emailed me a diagram of which bits went where. The initial outlay may be a bit high due to needing a housing. It's still turning out water at 008 after 5 years at around 50-90 litres per hour (variable). I have two resin vessels after it (only need one I suppose but I already had the other so may as well use it). I have the low pressure version without a pump at 35-40 psi. If I had a pumped system, it would produce much more - but I don't need more as I'm a sole trader.

Thanks chaps.

My water gauge on my present RO shows a steady 80 PSI from the tap (unless Mrs. Gold is running the washing machine and Miss Gold is having a shower!) - is that enough?
And is that variable 50 - 90L per hour the actual produced "pure"?
And how often do any membranes need replacing?

Walter, do you have a link to the RO you bought please?

No, be my guest - the more the merrier.

Mine's about the same age as yours, but it's like Trigger's Broom; I've replaced the three chambers, all the hose, and the metal bracket.

80 PSI ought to be enough for the ordinary 4040 (HF4 I think, though check with your supplier). The 50-90 litres per hour is the pure water production. However, that is quiter a low yield for this type of membrane; production is typically much higher and certainly ought to be if you have 80 PSI pressure (mine is 35-40PSI).
Ive had my 4040 installed for about 4 or 5 years, and it's still knocking out water at 008-010. I do turn the waste full on once or twice a week for maybe 15 minutes. I have 2 resin vessels after the RO. Probably only need 1 but as I already had them, I may as well use them,

I will check. It was from gaps water.

I bought the top one - the HF5 4040.
If you have decent water pressure or a pumped system, the HF4 4040 may be better for you. Phone them up and ask if unsure which to buy.
My initial outlay was quite high because I needed a housing and a few fittings too. However, it's been the most trouble-free membrane that I've had.
