Resin deterioration rate?


Hey guys, was cleaning with the WFP system today which measured 0 TDS on the last job and then at the end of this job (approx. 6hrs) it was basically same TDS as straight from the tap.

I was under the impression the resin would decline gradually, not like BOOM! Is this normal?


I am just jumping on this cuz I love this kind of tech stuff. Resin is a whole bunch of very small plastic balls. The chemical reaction happens at the surface interface. Balls are chemically treated for the reaction to happen. I am wondering if there couldn’t be a glitch in the manufacturing process that would cause such an experience? This would be what I would look into.

Could try asking Jack Sedore also. Go to the Glass Smart blog and click on the kitty to get to his youtube channel. Or go to the Glass Smart Facebook Group at ask to sign in and ask our little group of brainiacs. Of course we have a much larger group right here right now. Love the question.



Resin that we sale is mixed bed. Canton and anon beads. Some minerals attach to canton and some to anon. Normally one of the two will expire first so you will see a gradual increase in TDS. In your case 6 hours of use more than likely depleted both and one may have been almost used up when you started the job. The mix is normally 60/40 in the bed.


What was TDS from tap?

Curious if it was extremely high.


Look at this cart for Resin life


Our TDS here in Melbourne, Australia is pretty good, around 38.


That’s very interesting, thanks John. Also curious, sometimes (frequently) I have brain farts and plug the hoses in reverse. If tap water was going through the ‘out’ and out the ‘in’, could it affect the rate in which the resin is used up? I couldn’t see how it would, except that it wouldn’t be travelling through the carbon filter first… which would be harder on the resin… I just answered my own question I think.


Yes never run it backwards.
