Help with water changes, ATO and patience :)

The line in the the joists is just a clear 1/4" line from a filter system run to my tank, My laundryroom pipes put out about 80PSI so i have valves on both ends of everything lol. My laundry room is kiddy korner to my tank so I had to go the whole length of the basement to get it there. I used to run a chlorimine/chlorine block and add water 24/7 on a drip to my tank as its got a bulkhead in the sump that goes right to the main drain in the house. I just use it as a back up now incase something goes more wrong than i though it could it will atleast drain and not spill all over the floor.

If you watch your Tds out if the ro membrane you'll notice on startup there is a large spike before it hits it's stride. This is Tds creep and I use a valve to divert ro water straight down the drain until it subsides then allow it into the di resin. Not doing this and also allowing the unit to turn off and on itself without bleeding this Tds off will exhaust your resin much faster.

I have a before/after TDS monitor on my RODI system. I have only ever seen 1 or 2 tds (mostly 1) after the RO membrane, and always 0 after the DI filter. My incoming tap water is around 40 - 70. I also have 2 pressure tanks (3.2 g each) after the RO membrane (and before the DI), so that provides some buffering of flow from the membrane. And I have an RO only feed to a faucet on my kitchen sink, so I don't waste DI resin when filling water bottles or whatever.
