I've no experience with using an RO but inevitably I need to get one as my tap tds is now 213. It's a big shock coming from 025 tds in my flat. I only changed a 25L resin vessel 2 weeks ago and it's already creeping up and this is despite having another vessel behind the fresh one...

1. I have an outside tap with good water pressure

2. I'm NOT on a water meter

3. I have drainage

Ideally I want a portable 'plug and play' system on wheels.

Do you think I'll not need resin at all if I get a decent RO?

Thanks in advance guys

At that TDS your gonna need RO and resin.

Really? I thought a decent RO would get it down to single figures

It will but you'll still need to Polish the rest of the tds down to 0.

Our 40/40 RO (with a booster pump) brings the TDS to zero. Never bought resin in over 14 years or so. How much water are you using a day ? I'd be looking at one of them 450 GPD RO units for a sole operator , they are practically plug and play. You'd also need even a small IBC for it to fill into and then probably a transfer pump to fill the van tank from it. Very rough figures : 450 gpd RO £200, IBC £100, Transfer pump and hose £100...booster pump should you need it £100.

Thats not true at all mate. NOT using DI will NOT wear out the RO quickly at all. No one ever tells an RO if the water iss getting finished with DI or not so they tend to just do their own thing regardless

Yes your right, don't know what i was thinking there just edited it 
If your getting 0 with just RO what's your tap tds to start? Lowest I've ever got mine down to is 4 (215 ish to start).

Will wife let you put a big eff off IBC in the garage? If not you're bollixed.

Ours varies a bit between about 140 to 220 TDS. But i think its a bit of a minefield and different for everyone, i suppose its what the remaining stuff in the water actually is as to how efficient an RO is ? (as well as things like flow rate and pressure) .

I have not used resin in over 15 years. Product water from RO varies from 003-007.

I would use a 300 or 450 gpd RO feeding a static tank in garage. I use an ancient 300 gpd Roman RO with 3 x 100 gpd membranes. Daqua or Gaps Water is where I would go for advice.

[dazmond]

I want to purify water on demand with no IBC tank at the end of my working day. How long will it take to purify 400-500L straight into my tank?3-4 hours?

I bought one of these from Pure freedom for my garage when my TDS went from 050 to 350 overnight. This was about 6 years ago and it was priced about £1000 back then. Great bit of kit though and still going strong now, on the same filter too.

Takes roughly 90 minutes to take TDS from 300 ish to 006 and fill 500 litres then resin finish.

(TDS has dropped to 090 recently so it now takes it down close to zero)

12lpm with a booster pump that’s what you are  legally allowed to draw from domestic supply - I do not think those rules have changed.  From 720 lph max achievable would be half of that 360 lph realistically this drops to around 40percent at around 288 lph  at the high end . If no booster pump this will result between 90-120lph production subject to your pressure  and temperature of water. At 220 ppm you can achieve  4 -6 ppm water with no resin -  change required it is  to know when to rinse more ie dry windy days . Two choices 4040 hf4 boosted or hf 5 non boosted. In my personal experience with 325-375 ppm hf 4 gives me best results with longevity and performance - 2 years and still between 5-8ppm before resin. Hf 5 lasted only 18 months before going above 16ppm from 10.  If you choose boosted system look for one with flow and waste metres to adjust accordingly. Gate valves tend to fail prematurely in hard water supply. Needle valves offer better adjustment - can’t comment on longevity yet.

Thanks Danny. So can I just plug this system into my outside tap and fill my tank after a day's work?90 mins or even 120 mins wouldn't be a too bad time to fill up.

I think I'll wait until the start of the new tax year next week before I pull the trigger on this set up. It's £1500 now but worth it if its giving you 6 years of service and on the same membranes too!🙂👍

[AuRavelling79]

I use the Pentair PRF/PRO (Merlin as was). Been using one for over ten years.

I find that the Membrane gets me down to about 8 - 12 from a TDS of about 300 with a pressure of about 60PSi.

Absolutely NO NEED to be at Zero TDS. I am perfectly happy at 10TDS and even 12/15 if the membranes are getting tired. Then I use resin to polish off for a few months and replace the membrane.

I feed both me and Dan the Man water and neither of us get any complaints about spotting whatsoever.

If you look around you can get one with initial membranes and filter at about £500 plus VAT.

I always buy spares from Soap National - replacing membranes about once a year and filters every 35000/40000 litres.

I have a pressure gauge - important to be 60psi plus. And a meter to measure for filter replacement.

If I could give one bit of advice, It’s go big.

For the extra few hundred quid it’s worth the convenience of having a fast producing RO.

I’ve went from a 350gpd, to a 4021, and now a 4040.

I wish I’d just bought a 4040 10 years ago.

Yep just switch the water on and away you go. You’ll need a drain to send the waste also.

Thanks Danny. That sounds ideal. Did you get any instructions on how to use it? (as I haven't got a clue.)All I know is I have to flush the system every so often and change the membranes/filters every so often. Is yours the HF5?

I'm gonna get the same one as Danny's got from Pure Freedom. I need one that gets the job done fast and lasts a long time. 👍🙂

Hi daz this is my opinion and this is what I would do in your situation,some will agree others will disagree.

My tds is 270 ish for the last sixteen years I’ve had a  van mounted purefreedom  system 40 inch ro and two 20 inch filters one being a 5 micron sediment filter the other being a 5 micron carbon filter and a 9 inch resin bottle (not the same system as I’ve renewed the system each time I replace the van approx 3 to 5 years )
I change my filters and resin when my tds rises to about 10 which normally happens about every three months and has done for many years and the 40 inch ro used to last about a year but for some reason over the last three years with the same tds reading my ro has lasted three years and my tds stays at 0 for at leat four months this meaning three sets of filters from finer filters @ £35 per year  three nine litre bottles of resin per year and one 40 inch ro every three years  my current ro came from purefreedom before they got in bed with the new company.
What I would say is don’t mess about with trolleys and other stuff,if your putting in a good shift each day and earning good money just go with the above van mounted system you won’t regret it and it will pay dividends and it will look after itself with a small amount of maintenance,that’s what’s worked for me with a tds of 270 over sixteen years
And the above results are from a tap pressure of 60 psi no booster pump
