Is there a difference?

I currently just use two DI vessels, but I have a Tds of 075 so I'm going to switch RO to save resin costs.

Is it the case that pure is pure and that's the end of it?

Or is 000 out of an RO more pure if you will.

Just thinking out loud really, but the whole ro process seems so much more complicated does it take more impurities out of the water than just pushing the water through DI vessels?

Has anyone who made a switch from DI to ro noticed anything different?

[Don Kee]

You wont get 0000 outbof an R.O (i dont think) you'd still need to use a D.I

[Arnold Palmer]

At 75 in you will (should) get 000 out. I get between 60 an 22 from the tap - through RO is 000

No difference through RO or DI so long as it reads 000

At 75ppm mains I'd stick with twin DI, maybe try a change of resin brand if it's not performing very good.

how longs your resin lasting out of interest pal, i got 75 ppm too!

Not long to be honest mate.

I like keeping at 000 and I'm using about 500 litres a day, needing to change the DI vessel every 3 weeks ish. New bag of resin every few months.

RO will work out much cheaper for me.

At what point do you change resin?

You can safely let it rise to at least 10ppm - 000 isn't some magic number, it's just an indication of how pure the water is.  Try experimenting on your own windows, you shouldn't get any spotting even as high as 20ppm.

[mufcglen]

mine should last ages then, ive got 2 11 litre bottles and ive just started first one this morning and i'll be using 5-600 a week while i get to grips with pole lol!!

I usually change at 003 really. I experimented in the past and found that say above 005 in brilliant low sunlight I did actually get spotting. Customer wouldn't notice, but is like to be safer than sorry.

[SeanK]

I'm using a tds of 10 ppm at the minute and getting no spotting.
I check it on my living room window which gets full sun and would show up any problems.

[wfp master]

had a 100 litres of 14 tds yesterday used it all. checked a few house when i finished all looked good. gave the vessel a roll around the garden when i got home got it back to zero tds. i would use a tds of about 20 any higher i would change resin.

[Jonny 87]

It's hard to tell unless your looking inside out, Mayb I'm just paranoid,

All these people that use 0 parts per billion would have a hissy fit at 020 ppm. Lol

Just out interest, you may already be doing so

When using twin r/o a side issue(best performance di vessels for this purpose are 6x35. 13lt )  you can get a sack resin between the two when it's reading 003 or whenever you change take that di vessel which now becomes the vessel water goes through fist then you change the other one this becomes last vessel

Might sound mad if not already doing it but you will get longer out resin

That's what I do mate, saves a lot of resin costs.

[PoleKing]

Blimey lads, you lot are getting through some resin!
I use 13k litres of pure a month.
RO/DI just changed resin & filters after 6 full months as TDS got to 005.
OP, if you're not on a water meter, you may benefit from RO.
If you are, the resin costs saved will be negated by extra water charges.

I'm not on a meter mate, so RO is the obvious answer really. Need to just bite the bullet and spend out the few hundred quid. I'll have money back by 2/3 years on a RO.

It'll be quicker than that if you're using 500l a day bud.
I'm getting rid of my RO before April.
If you want a good 2nd hand one give me a shout.

Thanks Darren, think your right actually. I used to be 50/50 trad/WFP now I'm everything WFP so noticing my resin costs are getting pretty high. At he rate in using resin probably spend about £350 a year on resin.

 I'm going to be ordering one up within the next week or so though.

Thanks for the offer though bud.

I have a tap TDS of around 65, I have recently changed to an van mount 40/40 RO system, wish I had done it sooner, TDS from RO is 000, I still go through a DI to give the water an extra polish, the system will have paid for itself in the first year, I will then have pure water made very cheaply.
I installed an Auto-Flush control from Jet Systems, saves on all the weekly flushing.
Go for it, potential savings are huge.
