5 stage RODI left on, now numbers crazy high

[SaracensRugby]

So, I accidentally left my rod on for 1-2 days. Nice bit of water on the basement floor....I had just changed over all of the components in there, but now my output shows like 20ppm. It has never shown that high ever, even when the different components were depleted. Thoughts as to what's up? I let it run for 20 min, and still the same. Thanks.

Do you have a membrane flush on it?
Do you have any data on its input tds prior vs now?

My first guess would be that the DI resin is depleted.

DI resin is still the bluish color, will try flushing. The incoming water is around 20ppm, so I feel like it got backed up somehow. If that makes sense.

I would check the tds out of the membrane just to make sure it's working properly.

My guess is if the mixed bed DI has wiped out the anion but the cation is still good then your tds meter is going to read all sorts of wonky

Incoming water?

If your DI is working fine then you would be getting 0 tds out. You can put tap water through a DI and get 0 out... until it's used up... Then you get tap water.

Ok thx. Let me tinker around some more on this with the above ideas. Much obliged.

The input water shows 20ppm, is what I meant. There is a little toggle slot check invoking and out flow. If I’m saying that right.

Sorry don't know what you mean. Maybe take some pictures. Should be pretty clear on the connections and which way the water is going. If there is a flush valve make sure that is turned off after flushing. Does it have one of those auto shut off valves with the 4 tubes going into it?

Will take some pics when I am back in a couple hours. Appreciate it, as this is the first issue I have had with this rodi, in 7-8 years. The booster pump was off when it just kept running, when usually it is on. Think that is part of this at all?

 

[SaracensRugby]

Here is the in/out meter. Currrntly looking for the flush valve, if any on this.

I would try a flush, if not, letting it run that long likely depleted the filter. The worst crazy number is going to be the water bill at the end of the month

 

[SaracensRugby]

Flushed it, and put all new DI resin in and is back to zero. Thanks all!

My wife’s face looking at all the water on the floor is probably worse than the water bill, which she won’t see. .

Glad you got it figured out!
