Pretty sure this is the right area to post this. So I just replaced the three filter canisters of my 4 stage RODI unit. When I go to make water, it comes out registering at 3tds, then after about 2-3 mins, it goes back to 0. I bought some other tds meters to check the water with and they are reading back the same. I packed all the di resin very well initially and also checked for channeling after I realized there was an issue. I also just replaced the ro membrane less than 6 months ago, so I don’t think that would be it. The only slightly different thing is the psi is usually at 60, but it is currently reading 59. I’m honestly stumped on this and any thoughts on this would be greatly appreciated.
