Did my kid ruin my rodi?

[Burrito]

so I have my 4 stage Brs rodi hooked up in a bathroom no one uses with a faucet diverted and had it so water goes to the rodi. The system was off, seems my kid went in and turn the hot water on.

So hot water (like 110*) ran through for about 3 hours. Any issues ? Are all the filters toast? How would I know? This is my first rodi and ive probably made about 100g of water since I purchased it.

At least the output lines were in my tub...

Do you have a TDS meter on the inlet/ outlet of the RO membrane ?

The heat probably damaged the membrane, I would replace it. The carbon blocks may be okay. The deionizing resin should be okay, but may have depleted a little, faster than normal.

At 110 F I would say most likely not. But....I'd verify with TDS meter...ideally post membrane and post DI resin....a dual inline meter.

 

[sghera64]

Dow FILMTEC membrane (most common in the hobby) have an upper temperature limit of 113(F). Given the low flow rate and this line cooling you were likely less than 110(F).

There is a good chance it is fine at 110

I’ll check the dual tds meter results in the morning. In general is that how I would know when it’s time to replace? Is there visually anything to look at besides the number?

I get about 99+% rejection. Today, inlet was 355 and outlet was 1. So, 354/355 x 100% = 99.7% rejection.

Your membrane should give you 98% or better.

so my tds reads about 15 inlet and 0 outlet. does 15 sound low? compared to the 355/1 above..

Sweet Jesus I wish my water from the city was 15 tds

 

[redfishbluefish]

Let me make sure we're clear.....15 TDS is your raw water number out of the tap, or your number after the membrane? I'm assuming zero is after DI.

If that 15 is after the membrane, test your raw water number to make sure your membrane is knocking down your TDS by about 98 percent of better. That will tell you if you've cooked the membrane.

Oh [emoji19]

I doubt your raw water is 15TDS. I’m guessing that is the RO product water. Most units with only two TDS probes measure just before the DI canister and right after.

15 does sound high unless your feed water has like 800 TDS.

Let us know.

Probably toast, IMO. But look up the filters you use and see what their temperature rating is....then you'll know for sure. Call the manufacturer for the answers if you have to.

Why not hook it up to your cold water line with a valve on it. You’ll be able to use your sink anytime without worry and it would be impossible to cook your rodi.

Here’s one, I’m sure there are a bunch of different ones you could get:

Mine is 14

I accidentally turned the hot water on my vertex 200 gallon unit for probably at least 12 hours .The Ro membrains still worked but it took a lot longer to get good water and the water was so hot that the prefilter canister and carbon canister Actually swelled up and has to be replacedl

And I thought 31 was good...

Is that after RO or before????

Not sure, I honestly just walked over and took a picture for the thread. It's a "brs 199 standard" if that makes any sense to you. Too lazy to link to it, but it's the $199 version brs sells.
