How much does using the double di method save on resin.
My resin has come to an end and considering getting another di vessel and use the double method.
The cost of another vessel isn't the problem. Its the messing about.
I have my 25ltr vessel fixed to my van. I plug my house hose to it....done. So easy. I used to carry it about. Its heavy. I could put 2 vessels in my van, but its more weight and clutter. If it doesn't save loads, then I will leave it as it is

Why don't you purify on demand when at work through the DI vessel(s) .
This will save you money longterm and means you can fast fill your tank with water straight from the tap .

Not sure what you mean.
I do fill straight from the tap. Takes half hour tops.
Don't see how I could fill while at work anyway. Not many with a hose that would reach my van. Did it once when I ran out of water on last customer of the day

if your spent resin vessel is reading 010 say then you just put another fresh resin vessel in front of it and carry on using it until the spent resin vessel reaches your tap tds then throw away rather than throwing it away at 010.it could last another 2 or 3 weeks.also your fresh resin isnt having to work as hard so that in turn will last a bit longer.
you only need a few bits of hose and connectors and a resin vessel
i always do this.resin these days isnt as good as it used to be for sure.i go through around four 25kg bags a year using around 8000L-9000L a month(tap tds is 30-35)

Well explained Daz, been using this method for a while, and it cuts your costs down.

I know how to do it. My question is, how much resin do you save as opposed to using it single
-
you obviously save some.thats enough for me! ;D
-
It depends on your tap tds. You have to make sure you change the resin when vessel 1 goes past tap tds. If not it'll ruin vessel 2 quickly.
The trick to it is that the resin you throw away is totally used up as apposed to 10ish ppm. You'll know yourself how long it takes for a vessel to go from 10ppm to tap tds, that's how much you save.
-
It save me 28.5 % on average ;D

I hope all tds in Manchester is this low dazmond, I will be a happy man

Hi guys I have just fitted an extra di vessel on end of my twin ro system after speaking to someone at show so v interested to hear if 28% will be the same for me, I am getting 024 from ro then 000 plus the new di

The higher your input TDS the more you will save. It really is a no brainer- for the cost of one DI vessel it will pay you back in no time at all.

Fill you tank directly from your outside tap but dont run it through a Di vessel as you are filling up , Only connect the Di after you have filled the tank with non pure water .
Then locate your Di after your pump in the van the water will go through the Di much much slower saving you ££££ long term , Not something i have ever done but few lads on here have mentioned this method before .
If you are currently filling your tank through Di with the tap on full you will be going through resin in no time at all .

Bang on Mike. ;)
This is the most economical set up for DI only systems.

I've got a separate water softer vessel in my van which stands next to di vessel. I flush it through with new salt every month which I'm hoping will save me a few £££'s. I've been using it since February tds is still 0 so watch this space!
-
I have two DI Vessels at home and one on the truck. Using the non-zero tds as a filter on the input side makes perfect sense and ensures that the resin is never wasted.
-
i run two di s in garage same has you would in van but less-weight and the battery does not work as hard
-
twin di in the van, ive got the room for it so no issues there and i can top the tank up while out and about.
when i change the older bottle i always give the bottle thats going first in line a good shake just to make sure theres no water ways in the resin to get through easier.
i do about 500 litres a day with a tds of 75ppm and it usually lasts me about 5-6 weeks max.

Does this method slow your water flow down much to the brush?

None at all. ;)

Good
I'll have to try it
Cheers Chumbucket

But I use Vision in my tank. So thats a no go. Something ill try, if I stop using Vision.
Someone else told me, the slower the flow, the longer resin will last. BUT WHY/HOW. Same amount of water passing through it

Resin volume Vs water flow. If you took a 1ltr vessel with fresh resin in it & blasted water through it at full mains pressure & flow rate the water wouldn't come out at 000ppm. If you slowed the flow down to a trickle it would then come out at 000ppm. There isn't enough volume of resin to purify the volume of water being passed through it at that speed. Get back to the real world & take an 11ltr vessel, this will purify water at full mains flow rate but........ as the resin inside begins to get used up it begins to lose this ability on an increasing scale as the resin, now in a "mid-life" condition/state can't cope with this flow rate anymore & so the TDS starts to rise. At this point your resin is spent, however, if you were to reduce this flow rate, the resin, in it's "mid-life" state would still be able to purify water to 000ppm as the resin volume can cope with the reduced water flow being passed through it. So, the slower the flow through the vessel, the longer it will be before the TDS begins to rise resulting in an eventual higher volume of 000ppm water produced.

Be interested to know how this works.
I thought water softeners replaced the calcium and magnesium in the water with sodium which doesn't cause scaling in kettles and washing machines etc. but it doesn't actually lower the TDS it just replaces the solids in the water with another solid.
I thought about running a water softener as I use DI only but gave up the idea when I was told the TDS wouldn't actually be lower.

interesting. Just ordered new resin as my TDS is 002. I will try lowering flow down as I have a good powerful mains pressure. I use a 25ltr vessel, so I should get the most out of it. Oddly, I had 1ltr of new resin left. I tried replacing
old with new. Didnt do anything

Two 11ltr vessels are more economical than one 25ltr vessel. Pumping through these vessels & purifying on demand is more economical than filling your tank through them at a higher flow rate. It looks like there are two possible avenues there for you to save on resin costs.

What about 2, 25ltr vessels :)
and slow tap down ?
