RO filter issue

[littlehermit0]

What happened??? My RO filter was normal until I plugged it again and the water got from 0006 to 0120 ppm tds, I have been using this filter for 4 hours for now, it's new and the water was clean and everything until the 4th hour something happened and the tds raised to 120ppm what do I do????

Where is the TDS 120?
Pre Membrane?
Post Membrane?
Post DI?

Did you just fill it and start using it? Usually you have to fill / empty the new system before u. I did this with mine twice before using. I don’t really know why the TDS would go up though. Do you have an RO? Or an RODI? I ask because if your tap water has high TDS, then you will need RODI. Have you checked your tap water to see what it reads.

I didn't test it like that but the water that I basically got

RO and the tap water tds is actually low (210ppm), I only filled the canister and rinsed it and then it worked normally, all the 25L of water was good until that weird thing happened

Wait actually nevermind I tested it every second and got back to 15ppm

It sounds like there may be an issue with your RO filter. A sudden increase in TDS from 6 ppm to 120 ppm could indicate a problem with the membrane or another component of the system.

Everything is ok now, this post is very old, I found the issue it was warm water but I fixed it by just turning the water very cold

If the water was warm, you trashed the membrane. Buy a replacement membrane.
