DI stuck at 14ppm

[Cleanteam South west]

Is anyone else having problems with the DI resin, Tried to types now with the same result ( Tulsion and Unger )
I have even brought two new inline TDS meters thinking it maybe them. 14 years of doing the same thing and for the last 4 months can't seem to get it any better than 14ppm. Im now thinking the manufactures are using second hand recondition resin.

Are you going from RO to DI or Tap to DI? What input tds do you have?

 

[Cleanteam South west]

Tap to DI, the ppm coming out the tap is 65, i have not changed anything and been doing the sam for 12 years no problem.

Have you tested your tap TDS lately and is the Di stem / seal ok

TDS can alter daily just make sure there is enough resin in the vessel to prevent tracking , not trying to teach you to suck eggs but sometimes it’s just a simple thing that causes problems, also are you now using more water than years ago ? This would increase resin usage .

I will go and test tap water again, it can't be anything to do with the set up because nothings changed and both vans are showing the same.

Just tested tap water and its 144ppm
why would the tap water be higher its been on 64ish for 14 years

Possibly with new housing being built they have started supplying you from a different source. We have very hard TDS but still as a matter of course test our tap TDS during pure production.

I'm east Sussex south east coast my tds is 360 your lucky.

TDS can and does alter on a daily basis and time of year , also some water companies will draw water from different sources so this will also alter it , I think this is why your resin isn’t lasting .

Your Di Vessel probably is faulty. Is a new one or old one

I had a faulty vessel the filter on the tub had a 1ml gap that water was getting through

I’ve noticed that when we have very dry spells of weather such as lately and the local reservoirs get really low my tap tds jumps right up, sometimes doubling meaning the resin doesn’t work as well as it usually does. Maybe this is down to the water company’s pumping water between reservoirs up and down the country to make sure certain areas have enough?
Try slowing your tap down so that the resin has time to work on such a high starting tds.

It must cost you a fortune in resin even at 65ppm I have an RO as they are far more cost efficient longterm

Just brought a new vessel so will update when got it fixed up, i think its that because around the time i started having problems i removed a rusted screw from inside the head unit. at the time i just thought it was strange why someone had put it in there.

How much is it costing you on wasted water, as if my memory serves me right i had a RO unit for my marine fish tank and 80% was going down the drain.

Doesn't cost me nowt on wasted water as I am not on a meter and the waste water with a R/O is 60%

I can confirm it was the resin vessel that was faulty, thanks for all the info everyone gave it came in handy to get to the root of the problem.

Great to know, thanks for posting what the issue was.
