My ew RO unit which came with my Freedom trolley has produced so far 600 litres of water with a DI vessel the last thing for the water to go through before it hits the butt.
Why is the water now being produced coming out at 001ppm?
Ive taken the DI vessel apart and shaken the resin inside, flushed the RO for 15 minutes but the waters still coming out at 001 !! ??
Any pointers?
Or could the resin be cheap tripe with a dodgy life-span?

I run mine for 2 mins with fresh DI tank on before I get 0PPM. Stays at 0PPM for ages then.
-
matt whats the tds going in also have you just set it running again this evening or has it been running all day?
-
My tapwater goes into the RO unit at 270, coming out of RO its 15 (so this is the reading prior to going into DI), dont forget Ive also flushed it tonight.
The unit hasnt been on today, only turned it on tonight.

that all sounds pretty normal to me mate ;D ;D 001 is fine go back and check it in an hour i often find it takes a while to settle after its been turned off for a bit......now deep breath in......and hold......and relax ;D ;D ;D
-
I always disconnect my RO from the DI on my static set up and run it to drain for 3 or 4 mins even if it's just been off for a day. The initial litre or two out of the RO can be high when it's been sitting with water doing nowt in it. It soon settles down again.
I buy my resin from Freedom and it's good quality. Usually Dowex or Purolite but mainly Dowex.
Oh yeah and like Thorpey says... relax ;D ;D ;D

HANG ON......did you say 001 :o......oh crap :( :( :( :( ;D ;D ;D ;Dsorry ;D ;D ;D ;D

Yea 001, come on get a grip a grip man ;D

If you only have a 700ml Di cylinder and you are running your Ro through it as soon as your turn it on then you could be putting quite high ppm water through it, like Brighnclean says run your Ro untill its down to its lowest tds possible before connecting to the Di.
I made the same mistake when I first started, I have a pumped 4040 now and I still run it for about 5 mins before connecting it up.
-
Its been running nearly 2 hours now, still 001 ppm.

Chris are you saying hte resin can become contaminated if stagnant RO water is fed through it thats been stood for a day?
Matt

Take a deep breath Matt!!! ;D
1 PPM is fine.. it's been like that for 2 hrs now as u say.
Yes RO wter can use resin real fast if it's left standing for any length of time. The TDS creeps into the membranes and when u first run it again the high TDS will come out of the product pipe. Thats why I run mine to drain for the first few mins even after just a day with no production.
-
No what I'm saying is, I have found an Ro takes a few minutes of running until the tds reaches its minimum
when you have not run it for a few hours turn it on and check the tds straight away and before it goes through the Di, you'll will find it can be quite high but will gradually drop. It would pay to do it everytime you fill your tank up, as for the resin I always prefer 0 tds but you should be ok.
-
This maybe a stupid question, but is your tds meter accurate?
Perhaps the water is at 000tds, but your meter is showing 001tds?
-
Ive just found this
500000/tds/25 then x11
so 90 tds and a 11L di vessel will produce 2444 L of pure.
this does not take in account shaking the vessel
hope this helps
from here http://www.cleanitup.co.uk/smf/index.php?topic=38975.msg308890#msg308890
now according to this with a DI vessel of just 700ml then I should get about 900 litres of 000ppm water, seeing as its produced something in line with that amount, possibly in total 750-800 litres it doesnt seem to be that wrong (I think?)
-
Why the 500000 and the 25, Im sure there is a reason but otherwise would it not be easier to divide 20000 by your tap tds
-
and breathe..... ;D ;D ;D got any oxygen in your shed or is it all compressed air.RELAX MATE you gonna get in a state (mind you i was a nervous wreck for wks ;D) i regularly use it at 003 with no probs just stop fretting mate ;D ;) :)

jesus! 800 odd litres? since tonight?? what RO is it i have purefreedom 300GPD and it doesnt do that from 9am to 6pm and thats with booster pump :-\

I have already done 650l tonight with no booster pump, went on about 5:30ish

you have a 40/40 RO tho dont you? dont they produce more than a small 300GPD RO!
i think mat might have the 200GPD from purefreedom as that what comes with the trolley

I do have a 40/40, if Matt he has a 200gpd and hes done 800l i JUST HOPE IT IS PURE :-\

i have a 300gpd with booster from ro-man or gardiners really and that will give me around 450 litres in that time. In at 450+ ppm and out at 6.
-
matt does not say its produced all that tonight just in total ;D my 300gpd ro produces about 25 ltrs per hour seems to depend on temp......unless mines not working right :o see now he,s got me at it
-

I know makes u think! mines making 30 lit per hour with a booster pump! it was 12 literes per hour before that! i do think i can turn the PSI up on the pump but havent tried as am not sure how you do it so...
-
mark .how much does your system make in an hour with booster pump i have 300 and similar high tds, was it worth buying the booster pump? does it make much difference

what sort mains pressure you got dave iget that 25 ltrs per hour with no pump
-
im not sure what the mains pressure is! i havent got anything to test it with.
Might get one of those testing gages from ebay that you connect to your tap to see!

Calm down calm down !!!
Since Ive had it at the end of last week, cuh!!
Mr Thorpe, tell him to calm down like you tell me to calm down .
Anyway, I got it running through that rain-water DI kaboosh thing I made up , remember? so thats bringing it down to 000 anyway ;D

A little over 50 litres. The booster pump is worth its weight in gold. When i used the ro without pump it would come out around 15ppm and would take 10 hours to fill a rain butt. I've still got 1/3 of a sack of resin from march 06, so eventually the booster will pay for itself in money saved on resin. I dunno how long that will take though.
-
what booster pump do you have mark?
-
DAVE MAN calm down ;D ;D Mark ,how much? i assume it also reduces waste water production then i have tds 475 out of tap 010 out of ro so could be worth thinking about
-
am calm ;D am calm ;D
was gettin abit carried away :P
-
i have this 1. I bought from gardiners before but i couldn't see any on their website.

Same as minee!
Could you tell me how to up the PSI slightly?? is it behind the 4 little screws at the front? because undneath that there is a + - sign

i dunno dave?? Sorry. I've noticed but haven't touched anything in case i break it.

ok thanks anyway mark, thats y i havent touched it either because am unsure il get in touch with RO man sometime.
