Title: Adding a D I to Lengthen resin use ?
Post by: wpclean on March 31, 2011, 07:10:39 pm: When your tds starts creeping up from the D I vessel, I have been told to rather than throw the resin , to connect it to another D I with new resin !

It makes sense because the second D I vessel full of new resin is purifying water with a lower tds coming out of the first vessel with the old resin !

Definitely old before new, then once your tds starts rising, replace resin in "old" vessel and this becomes the "new" one

Post by: outdoor restore on March 31, 2011, 07:50:14 pm: What is the tds after RO? after first di?
Was the bag of resin sealed? if open to the atmosphere I believe it degrades, don't know about temp

Post by: Panorama on March 31, 2011, 08:01:38 pm: My RO brings my tds from 450 to 30, so that's working spot on, my first Di takes it down to 2 and the second Di was taking to 000 but it's creeping up already ???

Post by: Pureclean Essex Services on March 31, 2011, 10:24:03 pm: you can also take off the used resin vessal cover outlets and give it a good shake up,refit this brings down the tds,so you get full usage out of the resin,keep doing this until it's shot,then refill with new,Brian.

Has the tds after first di increased from 2, if not, your problem is only with your second vessel which would suggest it is not your resin. You have got the inlet/outlet the right way round? and the head is screwed down properly?
