![]() Just setup a new Captive Purity RO/DI last weekend and intially the TDS meter measured ~172 ppm on the water IN, and 0 ppm on water OUT.
I shut the water off after my reserve tank was filled, and ran the RO again last night to top-off my tank. Had it on for about an hour and the reading OUT was around 7 as opposed to 0. Any thoughts on that? ![]() |
