Your client fails a NITRATE or LEAD test, installs an RO under the kitchen sink but the re-test still fails. Why? The biggest reason re-tests fail is because the newly installed RO was not run off properly. The RO cannot just be hooked up and you are good to go. You must fill the tank underneath, then run off an entire tank and refill again to truly obtain filtered water. Professional installers know this, however some homeowners and handyman installers do not and assume the filters work upon connection. Make sure you pass along this tip when taking water re-test orders and your client won't be disappointed.
