DI system only system questions

Between the carbon block and the RO membrane is a great place for bacteria to grow. No disinfectants, and plenty of nutrients in the tap water. The RO membrane mostly keeps bacteria out of the product effluent.

Recently we were at a customers house changing the filters in the Ro system. Their system was not producing much water and their membrane was not rejecting any TDS (total dissolved solids) which is the method of knowing whether or not your RO unit is producing purified water. Upon removing the canisters in which the sediment filter and pre-carbon filter were we found some serious slime build up. It was a gelatinous mass that had built up in the filters as well as within the RO manifold blocking the ability of the water to flow freely throughout the ports. The membrane had also been contaminated with this gelatinous mass. What was the gelatinous mass? Bacteria.

Amazing I thought light would be a necessary thing for that I guess not considering lets say a wound. Scary

That is why it is recommend to sanitize a drinking water RO system every 6 months of so.

After seeing the condition of my filters after 6 months filtering city water ( however is treated after it comes out of lake Erie ) I cannot bring myself to trust an RO system to drink. Now with Randy's input even less. I have seen and put more stock into a system that includes a UV in line light. So randy would that put where? Stop the bacterial growth?

Yes sorry for taking over but I thought you wanted to save water as well which is why I mentioned what I use

No worries . I appreciate your comments.

Forgot to say it would even happen easier because of the single lever designs you could very easily be running hot for a while also people my self included rinse their mouth with warm. Have you watched the documentary on food poisoning? It started in the 60s with hamburg ended with the peanut king who knowingly killed 8 people and only got fined. The worst thing these days is bagged mixed salads apparently

I'd UV treat any water coming out of the system that might end up being drunk. Assuming you do not drink the di produced water, I'd put it on the line sending water into the hot water system, somewhere just before the hot water pipe junction.
