Hi guys, I run a di in my van, reason for is 'peice of mind' I'm thinking of taking it out now, running pure water into tank and not worrying about the di In the van. Obviously I'll use the di after the ro, and it'll be 100% pure going into the van tank,

What do you guys do? I've had it in the van before the hose reel so it's as pure as can be just before it gets to the brush! Not sure if this is necessary?

Reasons for...
You know exactly what your tds is going to be over the complete days work.
Don't have to carry the DI bottle in the van.
Reasons against...
When the R.O. starts to produce pure the TDS takes time to come down so this will shorten the lifespan of your resin.
If your R.O. causes problems and doesn't reduce the TDS then you will waste your resin as well.
Chance of waste water running into the resin when flushing.
This ones only my opinion but I believe that an R.O. membrane lasts longer and works better if there is no back pressure
at the pure outlet having this connected to an DI chamber stop this free flow to an extent.

[Jakey boy]

Interesting points, I'm just thinking it'll free up space, improve battery life as pump isn't having to force water through resin, and less likely to have leaks as less connections...

I really don`t understand a di in the van a mate of mine has it this way and its always leaking. AS above said, killing your battery, it just makes sense to have it static with the RO and tank.

Yeah I'm thinking your right... I may well take it out this weekend...

I have to say I've never had any orobs from either of my di's leaking but I'd like the room they take however for me I full tank straight from tap so I imagine it would burn through resin quicker from tap rather than just 12v pump pushing it through also if I'm out and about and run out of water I can fill up anywhere knowing it will be pure before it comes out!

Doesn't benefit me as tds here is over 400, so a ro is always needed, but yeah if all you need is a di, may as well leave them In van...

[SeanK]

Why would it leak, mines been this way from day one and has never leaked yet.
I have both the R.O. and the D.I. in the van and it makes perfect sense, just connect to the tap
at the end of the day and leave it.
Don't have to have an extra storage area or have to pump water from one tank to another.
Different if I had more than one van on the road.

[Jakey boy]

It doesn't leak, but there's more potential for leaks

I've been window cleaning 9 years and I've never used a DI vessel in the van - I've never had any problems with high TDS at the brush end... It comes out of the static tank at 000 and hits the window at 000.

In my mind having a DI vessel in the van just takes up space and gives you more connections to worry about.

In your situation there isn't really anything to be gained by having the DI on the van. However, in a DI only system it's the opposite- there is everything to be gained but because you use an RO anyway there's little point explaining why.

Yeah I can see your point, fair enough... I suppose with a DI only system you can just fill the van tank up with tap water.

Just taken the di out, thanks for opinions! From
Now on it'll go into the tank at 000 and that'll be that!

[mufcglen]

Jakey boy are you putting water in from ro or straight from tap as you might want to turn the two flow down when filling tank straight from di and tap as I've been told that direct from the tap can burn through resin quicker if your just doing tap to di rather than using ro as well, whether this is true or not who knows?

[Jakey boy]

No i use a ro and di, tds is well over 400 here, so I'm now going to run ro then di into storage tank, then into van tank via transfer hose.

What are the reasons for having a DI container sat in your van if you purify your water initially with an RO? What's that all about?

That's just how I was told to do it when I went wfp, the thinking is the ro brings the tds down then the di in the van polishes off before brush head, why? I've no idea, I'm now running pure water into tank after ro and di in shed....

[DG Cleaning]

Right, here goes.
I run twin DI's after the pump and before the reel.
It never leaks.
My tds is low so I don't need an ro.
If you fill your tank up through your di the increased pressure and flow causes the resin to go off quicker hence why it's after the pump.
There is virtually no resistance for the pump so the battery doesn't run out quicker.
If you don't believe me try blowing through the inlet side if your di.

That's my thinking as to taking the di out, more battery life... Also don't know why I was told to stick a di in the van when I'm using a ro anyway! Ah well. It's out the van now now my system now is RO>DI> ibc tank > van tank.

Beifre it was RO>ibc>van>DI after pump... Was pointless really...

Exactly how I'd do it in your situation but no it makes no difference to battery life
