Quite possible a real dumb question but I have an 8ltr di i am about to refill with new resin how near to the top do i fill it? ???
-
I always do mine 3/4 full.
-
fill it to the top, then bang it on floor it will be about 3/4 full ish ;)
-
Same as Ian and Stuart.

I have always filled whatever size resin vessel as tightly packed as possible, packed too loose and the water can form pathways, hence why giving it a good shake when tds starts too rise it gives the illusion of getting more life out of your resin, when in reality all you are doing jumbling up possible pathways and having the exhausted resin mixed back up with the resin that hasn't been fully utilised.
Packed tight all of the resin gets used equally....of course if is TOO tightly packed it can restrict the flow!!!
And here is a thought with regards resin in general;
Most will wait till their tds has reached double figures before changing it, but just how pure does fresh resin make our water?
Yes, of course I know it leaves us with water that has a tds reading of 0.000 ppm, but that is because that is all our meters are calibrated too.
Pure water as is used - for instance - in a forensic lab is measure in parts per billion as against parts per million.
Ultra pure water for instance will not freeze solid until the temperature is several degrees below freezing.
Anywho, the reason for mentioning it [apart from sheer curiosity] is that since having a DI vessel in my van, rather than with my static tank I've noticed that many of the windows that I've always considered problematical are coming up spotless with far less effort.
Which has led me to wonder just how pure fresh resin will actually leave the water we produce....

Ian
does that mean resin that is left in van being used daily is better ? :-\
Ian
p.s serious question incase I am classed as mocking which I am not.

Thanks to all-the good thing about this board is the great advise that is given out helps everone out.

Pack it too tight and you wont get the riser in.

Well I certainly noticed a difference and I wasn't even looking for a difference.
Advantages are more than the disadvantages.
For instance, no resin wastage if you forget to turn off your tap and end out overfilling your static tank.
You can also top up from a customers house if you run out of water, might use up your resin a lot faster but at least you could keep working.
Any contaminants in your static tank - algae for instance - won't get through your resin vessel.
Much easier to keep from freezing in the winter too, WCW had shed loads of window cleaners having to replace resin and pre=filter vessels due to winter freezups.
I think it is more efficient and cost effective, and I like the separation between static and van tank, if I have to waste a full tank of pure from my IBC (cock ups DO happen!} I know I won't have wasted resin in the process.
And as already mentioned...there seems to be far less risk of spotting.

Ian (Giles), where do you position the DI vessel? before or after the pump?
Matt
-
After the pump Matt, and before the hosereel of course! and doesn't effect the flowrate...or at least not that I have noticed.
Ian
-
Ian do you have any problems with resin escaping in to the water as you are cleaning?
Just curious as I can remember someone last year having this problem, and he bought an additional pump seive.

Ian what is your TDS before going through the resin.
-
No, none whatsoever, at least with the resin vessel that I have, which was from WCW.
Filled correctly and seals properly in place there should be no problem, it's only when you fill you might get stray resin granules, that isn't to say I WON'T get any problems, just that I haven't as yet!!
Stuart,
Currently I have a 4040 R/O and after a slight glitch my tds after the R/O is around 0.006 ppm.
The R/O is over 12 months old now.
