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

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

Thanks for that Colin. The one I'm getting is exactly the same as yours but not van mounted( it's mounted on a frame instead) from Pure Freedom. No room in my van for a van mounted RO.👍

Ok daz that sounds good to me

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.

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. 👍🙂

Pretty sure it comes with instructions but it’s really easy. Plug in your water supply with standard garden hose fitting and turn tap on. Direct the waste down a drain. There’s a switch to change the waste ratio, can’t even remember the settings as I havnt touched it in 6 years.

One thing you will need to do is work out your water pressure to see if it’s a HF4 or HF5 that you need. Pure freedom will talk you through this if needed.

More than welcome to come and have a look at mine before you make the purchase, you probably pass my house on the way to your village work everyday.

Thanks Danny I'm going to order it tomorrow(start of new tax year). I'm going for the HF5 as it produces more pure at a lower water pressure so saves buying a booster pump just in case my water pressure is lower than optimal. Although it's powerful on full flow apparently that's not an indication of good water pressure

[dazmond]

How often do you change the pre filters Danny?( carbon and sediment). Did you say you've never needed to change the membrane yet?

Cheers Danny

I thought my pressure was good from outside tap because it was a pretty fast flow and force......when I put it through the  PF  high volume RO system it was only showing 30psi so check it first.....at 30psi it's useless, had to buy booster pump.......last changed the resin on the system about 15 months ago as TDS here is about 80.........TDS jumped up to 270 round here  so was burning up resin so bought the system......4 months later it went back down to 80 again so a bit of a bummer really.........mine does about 125 litres an hour at 100psi in  Spring, Summer and Autumn bit less in colder months.

Is yours a HF5? As that's the one that still produces high volume pure water despite lower water pressure. I'm hoping I don't need a booster pump. So it's taking around 4 hours to fill a 500L tank? Danny says his takes around 90 mins and he doesn't have a booster pump.

Why is it a bummer? Surely if your tap tds is 080 again your RO will get it down close to zero so no need for resin at all (saving you money in the long run).

Thanks for your input mate.

If your TDS was too high to DI only over the years in your flat, how would you have gone about making your water for work Daz?

I buy about 4 carbon and sediment filters at a time and probably  change them every 4 months or so. I’ve not had to change my RO since I installed this static RO about 6 years ago.

Dunno....but it wasn't!😂

It was hovering around 025 most of the 15 years I've been WFP.

Ironically it's perfect for an  RO here. Outside tap on my driveway with drain underneath and no water meter.👍

I expect your TDS meter was faulty Daz, I bet you were using 200 PPM on your customers windows for 15 years but they were to frightened to complain .  always best to have two TDS metres

I have got 2 TDS meters.....the lowest my tap water was in Salford was 018 I think. It's a very soft water area.

It's harder here in Warrington. It's currently 211 and I'm still using resin only(using 2 bags a month and that's with  2 x 25L vessels in tandem)

[JandS]

It's a bummer with the RO because it wastes water and I'm on a meter and it's more faff for me.........DI was quicker filling and I only changed resin around once a month.......used to do some schools and could take the DI with me and top up on site.

Your water bills must be astronomical especially with the predicted rise in bills over the next 5 years.

Surely it wouldn't be any less expensive to just run double DI for you over the course of a year.

I was fully prepared for using a bag of resin a month DI only for convenience but I'm using 2 bags per month and I only work 4 short days per week! So RO it is. Luckily no water meter.

Is it true ROs need to be set up for waste 60%/40% pure?

Just have a play with the system when you get it Daz. Increasing the % of the waste will slow down production but be kinder on the RO. Just depends how quick you want the system to produce. You’re not on a meter like me so increasing the waste won’t effect your water bill.

[JandS]

How do you increase/decrease your waste ratio?

Daz.....bought the system when my TDS  shot up to 276 from 80 in August 2022.
It came back down to 80 about 3/4 months later but by then I had committed........about £65 extra on my water bill but was paying about £30 extra with DI anyway plus 4 bags of resin a year.
Mine's an HF4.

[dazmond]

If your RO gets your water down below 010 do you not bother with resin to polish it off to 000?

[JandS]

RO gets mine down to about 1/2 then through DI.....no need for DI for me really but it's built into system so might as well use it....can't remember last time I changed resin but only done it once since new and it was new in 08/2022.
Bet it's 18 months ago and still getting 0 TDS and 1/2 out of RO before DI.
Any ideas how you increase or decrease waste output on these anybody?
