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.

It will but you'll still need to Polish the rest of the tds down to 0 with Di if you don't use Di it will wear out the RO quickly too..

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.

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.
