I use 2 vessels in series and change when it gets to 30ppm.. My last resin change a few weeks ago and i must have forgot to swap vessels around and so the high tds vessel is still in place checked just now on the off chance expecting it to be between 5 an 10ppm to find my tank is at 121ppm!!!

For the last 2 weeks we have been cleaning with between 30 and 121 ppm.
Im going out now to go and see the outcome on a load of houses that have been cleaned by both vans which is over 400 customers....gulp..
Fingers crossed all will be ok.
What a total idiot i am  . .

Could have been worse











Could have been me

[DG Cleaning]

I did a full day on well over 100ppm, didn't get a single complaint and when I checked the windows they were fine.
For some reason my ppm had shot up from 5 in no time.
I check it every time I fill up now.

[PoleKing]

Just goes to show. Don't do a 'perfect' job cause your customers can tell when you do a crap 'un.
Blame the weather.

Just got back after looking at 100 odd houses..There were signs of spotting on every house that i checked but only minor which maybe has something to do with that its a dark wet day so not showing so great!
If the sun was shining on the customers glass im guessing it would look a different story and the phone would be ringing nonstop..
If i get any calls of complaints ill go and redo and not charge this time round..
I also have another cleaner who i sell pure water too as well who only filled up this morning who i cant get hold of to tell...that should be fun.............NOT.
Thankfully i have had no complaints as of yet. I guess as said i have the bad weather to thank that if i get away with this balls up!.
I defo wont be doing that again in a hurry.

If you are using 2 DI vessels in series it is a false economy to leave it to get to 30ppm before you change it.

If you think it through - by the time your product water is 1ppm the resin in your first vessel is completely spent and is dishing out water higher than it is getting it. That is why it shoots up so quickly. If you change it then your second vessel will be getting relatively pure water for a while and will last longer.

I don't clean at anything other than 0ppm.

ive used it a 10 and had complaints, so wont go above 5 now

Tap 360ppm
Merlin 37ppm
Vessel 1 0ppm
Vessel 2 0ppm
After about 6 weeks vessel 1 creeps to 20ppm vessel 2 stays at 0ppm so i shake vessel 1 which lowers it to 7-10ppm for another week and repeat process untill it reaches 30 which is when i swap for vessel 2 which is at this point between 0-5ppm and refill vessel 1 to go in vessel 2's place and i repeat cycle over and over however this particular time i must have for some reason muddles the 2 vessels up and refilled the wrong 1 and put vessel 2 in vessel 1's position with old resin that i never bother reading the reading as im more interested in vessel 1 being under 30..
Anyway i know it normaly works the way i do it and this was a total big mistake on my behalf..

Let's hope it's not a sunny morning over your way tomorrow  

If it's dull and then raining you should get away with it...

Sorry to disagree, but resin is not totally spent at 001 what it usually means is the water has finally tracked a path through the resin where it can no longer hold the dissolved solids, as do vessels have non flow areas there is loads of life in resin and a good shake up proves this, you get even better results emptying and refilling as resin producing say 005 will return to 000 for some time.  As Mick gets 037 from the RO then he is making the most of the resin by waiting to change it at 25 to 30 as it IS still working ( if only just )

i check my tds every evening as soon as ive filled my tank.

im currently running 2 DIs(no RO).i checked my tap tds tonight(31 tds).my first resin vessel is getting it down to 010 and the second is getting it down to 000.

in a few weeks my first vessel will get to my tap tds level.when that happens ill just use the second one until that gets to 05 then put a fresh one in front of it and so it goes on and on and on...........!!

this way i get the most out of my resin.

i know!i know!....im very lucky!!! .


lessoned learned eh?mick?

if you get into the habit of checking your water every night it just becomes part of your daily routine.


very best wishes

Verey lucky lol..
Lesson learnt good and propper!.

Resin is far from spent at 001. Resin in vessel 1 will not be 001 though.

Mick - that sounds like quite a lot of fannying about to me. I wait till my product is 001 then switch it, whenever I empty vessel 1 it's output is higher than the water going in, it is spent - you can see it when you empty it.

[roundbuilder]

It sounds like a lot of fannying but it isnt..a sack of resin lasts me 3/4 months which isnt bad considering the watter is so hard down here compared to you. Id be chucking money away if i swapped vessel 1 at 001ppm as it takes only a day to reach 001. I simply shake vessel and use untill water hits 30ppm.
Looking at getting a boosted 4040 over the next few weeks though so hopefully water out before di will be between 5-10ppm so hopefully a sack will last a year then.

i use 58ppm most days,old style glass wooden framed not a problem
new builds the same,leaded lights all these dry clear no spotting
all the glass on these windows dries evenly.

The only time i get any problems is with hydrophobic glass
 whip out a pole and blade...problem solved

why 58?

[Arnold Palmer]

Do you use standard bottle type DI vessels?

I have 1 with EZ pure horizontal style cannisters, the process we use for that is similar to yours - where shaking will reduce ppm - we don't get 'channeling' in the bottles though.

[Dean Taberner]

I use tap water in stoke, TDS around 300. Never had a problem.

[roundbuilder]

Had a text from a customer saying she wants to cancal untill further notice so i replied is it because she wasnt happy with the clean and she said no nextdoor are having building work done and its making her windows dirty as soon as i clean them...
Well maybe that is because of the builders but im thinking may e its because of the tds of the last clean... Anyway the end result was she wants them done when building work has finished.. Pheeeew
