What am i doing wrong do i have to let it run longer to get a low level my tap water is around 600, if someone could help i would be very gratefull thanks in advance.

Anyone?
-
phew 600 s thats high strange ow di s
only taking 5ppm off though
mike cam s yr man for tech stuff ;)
-
600 wow!
Maybe another DI after is needed. My RO takes water down to 20 - 40 then, i found the little 1 litre DI vessels werent up to the job so i have a 11 litre DI in van to polish it off.
-
If your RO is taking it down from 600 to 40 then there's nothing wrong with the RO. Your DI should take out the rest with ease, are you using resin or packs?
I would change the resin in the DI and try it again, if you put 600 water straight through the DI it will f*ck the resin in no time.
-
how long have you left it running,they do take they time to settle down, ;)
-
Have you checked to see if the filters are sat in the housing correctly. An ill-fitted filter will allow water to bypass it, thus allowing dirty water through.
Take all your filters out and rreseat them, making sure theyre sat and sealed perfectly.
-
i had the same problem, check the di cartridge is sat right as the top black seal needs to be in the right place also check the resin you neeed to make sure there is enough in the cartridge so top it up and make sure its compacted in the cartridge if all else fails order a bigger di i have now got a 11 litre on takes my water to 0
i get 190 out off tap to 9 out off ro with the old little di i struggled to get it below 2, i think they are not up to the job realy
-

I left mine running for 2 hours when i bought it

-
As said before you need a bigger di vessel.
-
i have that same one sat spare on a shelf.
my tds is 400ish before it went into the di it was down to 20 then out at 000.
so your water going into the di is high, doesnt the manual say it should be around 20 if working right.
now the di has had water through it i wouldnt try to get the filter out, disconnect the pipe and give the rest a good flush through.
-
With a tds of 600 a 4040 would have been a better option
-
Hi thanks for all your help i have took out the DI and left it running without that, and it's down to 37 at the moment, so it seems like the DI isn't making any differance,(why would this be?).
I bought this system as it was quite cheap i thought and had the booster pump as well but im on a tight budget i only want enough water to run my backpack for hard to reach windows so im not looking to make loads and loads.
-
You really need twin 11ltr di's,but its obviously more money which defeats your objective. With that system,your tds will never be low enough not to exhaust the resin cannister supplied
-
If i fail to get the TDS low enough with what i have would this be a good buy, or would i be better off buying an empty vessel and a 25ltr bag of resin.

-
If your tds is accurate then yes,that is the vessel you need. The one you linked too is very expensive so get two seond hand ones off ebay and a 25ltr bag of Tulsion. If its for a backpack then you won't need to change your resin for mnths/yrs
-
Just out of interest, where are you with an input of 600?
-
Hi i live near newmarket suffolk, the TDS meter is new but you may have a point even new things can be faulty,i did try it in some bottled water and it read around 90 (should bottled water be lower i dont know).
Ive just been out to check it again and whatever i do with the DI whether it's in or out ive even tried it both ways in the housing but im still getting no better than around 35.
-
Put a post up with the heading Newmarket and someone will tell you what their tds is. 600 sounds more like a waste water reading

Why would i need 2 11ltr DI vessels why not just 1?.
-
OK, here's some info.
I live in Southampton; the measures for my water versus yours ( from http://waterquality.anglianwater.com/map.aspx using a newmarket postcode ) are:
SO15 CB8
CaCO3 262 329
Ca mg/l 104.8 131.6
°Clarke 18.34 23
°French 26.2 33
°German 14.67 18.7
So you look like you have about 25% more dissolved salts than I do. Unfortunately the water companies don't do TDS numbers, just the ones above. You might want to try your own postcode in there in case I've picked totally the wrong area.
My water has a TDS of 279, so your reading of 600 sounds VERY suspect to me. Should be nearer 350. Something's up...
Hope this helps,
Vin

Thanks by the looks of that mine should be higher than yours but not that much, i may buy a bottle of deironised water like someone surgested then ill be sure my meter is working right thanks for your help.

Long story but two vessels will last 3 or 4 times longer than one. One would be ok for the amount of water you will use,but two is the way to go

Well i think ill have to go that way as my fitted DI seems to be totally failing, wheres the best place to buy the resin? thanks.
-
DA Resin supplies or J V Price
-
What price roughly should i be paying for 25ltrs of resin?.
-
£73 seems about the norm. Most people go to DA
-
Ive decided to go the way of 2 11ltr vessels but as im not that clued up yet is this correct for what i need?.

The resin is free postage so doesn't look a bad deal, im itching to get going with my backpack so i need to get sorted, when i do get the vessels how full do you fill them? thanks.
-
Both of those are perfect. When you get the vessels let us know. I think there are vids on youtube of how to fill them. Unscrew the lid, fill 3/4 full with a funnell or similar,fill with water and crew the lid back on

Thanks very much for your help.

I have a similar RO to yours and it works very well. The tds should imporove after a few days use.
A problem I had with mine when new is that it had 2 faulty membranes (3rd one OK - 300gpd unit). Try taking a seperate tds reading from each membrane to see if they perform equally. Apparently if they are stored for a long time they can start to break down.
-
no body as said a bout your water pressure.
what is it.???????
dont say it seems good get a gauge cost £9.low pressure sometimes means high tds from membrains.
if you are going to order a di then get from someone who know what there on about and great service with next day del
speak to doug at http://www.daqua.co.uk/divessels.htm
-
A di is a di no matter where you get it from,its the resin that matters. Why buy a new one from da when there is a second hand one on ebay for £20ish?
Mains pressure will never be below 40psi. At 40 psi you should still be getting a tds reading as high as 15. If you drill out he hole into the feed water pipe this will allow more water to access the ro. Unless your ro is a mile away from your tap then pressure/flow rate should be fine
-
My mate had the same problem and when he eventually looked in his resin vessel it was empty! have you checked?

mains water never below 40psi sorry luther you aint got a clue what your on about.
come around my house and i show you below 40psi.
di vessel ok you know it all
-

Yes i have checked that but what i cant understand is there is no differance on the reading whether the resin is in the housing or not.Running thorough without the DI im getting around 35 how long should i let it run through the resin untill it gets lower or should it be quick?.Even if the DI isn't performing very well it should still make a differance.

Didn't know you lived in Suffolk. But i wouldn't know that would i,cos i haven't got a clue
-
I didn't want this thread to cause arguments everybodys got there own ideas and thats what makes these forams work luther1 surgestions helped me decide which way to go and a cheaper way as my budget is tight.
But the water pressure thing may or not be an issue but my main problem is why doesn't the DI fitted to my RO make any differance thats what id like to know.
-
Your di was probably filled with regenerated resin to keep costs down and with a tds of 600 it would get 'spent' very quickly. Even a decent resin wouldn't last long.
We're not arguing,just having a friendly debate. No malice intended towards each other
-
Btw,i don't confess to know everything and there are certainly people who know much more than i do but i've been wfp for nearly 10yrs now and have encountered nearly every problem along the way,had nearly every make of van,pole,equipment and will always try to help,as others have done for me. :)

The DI vessels came as did the resin i now have a reading of 000.The 10" DI canister must have been useless i have left it in the housing is that wise? or could it also be filled with new resin?.
-
at this moment you are getting a reading of 000 with the following set up. RO into 1st DI ( with your original resin ) into NEW DI ( with brand new resin ) then pure water into IBC. when your tds starts to creep then do following................... RO into NEW DI ( with resin ) into your original DI ( with brand new resin ) the pure water into IBC. doing this will exhaust your resin and save you money in the long term

Hi my system runs through the RO through the 10" DI then to a DI vessel with new resin on to a second DI with new resin into the water storage tank.
-
::) and at this moment it's reading 000 ?
-
Check that the di vassell in its cannister is the right way up, if its the correct way up and the tds is still high then refill with new resin.
-

Just don't leave the old resin in it as this will add contaminents to the water.

The RO setup you bought seems like have 2 pre filters and DI.
I believe usual RO has 3 pre filters CLICKY (http://www.purefreedom.co.uk/10-reverse-osmosis-prefilter-set-p-322.html)
You might buy that missing filter and add a seperate DI unit (http://www.purefreedom.co.uk/10-complete-di-resin-filter-unit-p-437.html)
I don't know if that extra pre filter makes a change.
Also the DI resin came with the setup might be rubbish.
Get a liter of quality resin like this (http://cgi.ebay.co.uk/DI-RESIN-TULSON-VIRGIN-MIXED-BED-1LTR-/260516161036?pt=UK_Pet_Supplies_Fish&hash=item3ca7f9260c).

Hi
Water round where we are is usually at about 350
We have the water going through a water softener system first before it even hits the RO/DI etc, might be worth trying that
see link for example
