My old man has a handheld meter he is going to lend me. I mix and store in Rubbermaid I have a 20 gal brute can for mixing and storing saltwater and a Rubbermaid slim Jim 16 gal I use for transfer from ro/di into a large 150gal vinyl water storage “bladder” I haven’t used any of the water I’ve put into the “bladder” tho. I barely got it and was filling it up when the mixed bed all the sudden went bad from one time seeing it to the next. And I’m talking from top to bottom. Up until that point the only resin depletion I had was the anion stage and it is the same as in the pic. About halfways but I’ve made a fair bit of water and also needed a check valve to stop air from entering the canisters causing excess depletion. When I first noticed the amount of air in the system and depletion were equal.
The small town I live in has two water tanks up on the side of the Mesa on the “side of town”. One tank is less than 15 years old I wanna say and the other is older than I am. By a long shot it’s from at least the 60’s or maybe 70’s. So it could a possibility that’s the case. I was able to take one of the meters off of my triple di saver and put it in front of my ro unit to test the source water and it was registering at over 500ppm!! I also have video to prove it cause I’m sure a lot of ppl won’t believe it. I let it run for about 3 mins as well first with the water valve wide open then I slowed it down a bit by closing the valve some it has great pressure. I need a gauge to test it tho. I have one in my brs cart right now jus need to place the order.
I jus find it odd that it didn’t start at one end and work it’s way to the other like the anion resin has been, it was like a light switch. One min it was fine no depletion at all then the next it was completely gone from top to bottom without a bead of blue or purple or whatever color it was. I added a check valve to keep the system from draining and sucking in air while not in use. I noticed one day that my anion depletion was equal to the amount of air that leeched back into the canister from it sitting with no pressure to keep them full of water.
