Did I just kill my RODI membrane?
 

I don't have my Aquasafe plumbed, I just have it mounted on a rolling cart and hook it up to the tap in the kitchen with a faucet adapter. I guess today when I was hooking it up I didn't pay attention to which tap I turned on. I had the hot running for about an hour before I went back to check on it and realized my mistake. It's making water now at the usual rate and TDS hasn't changed from before.
Is this going to cause me issues now or later? The whole system is about 4 years old now, so it's not a huge deal, but if I don't have to spend the money to buy a new one, that would be good.

Not sure if wreaked but towards the end of life for a membrane anyways. Would say though if still working okay I'd take as a positive sign you're good.

Might find this interesting if and when you go looking for a new membrane

I'll keep that in mind when I replace the membrane.

Thanks Mark.

should be ok but keep an eye on the TDS after the membrane
