(55) Stand-alone PIWF--A PIWF that does not share a water supply, disinfection system, filtration system, circulation system, or any other treatment system that allows water to co-mingle with a pool as defined in Subchapter L, §265.182 of this title. This does include a PIWF that shares a water supply, disinfection system, filtration system, circulation system, or any other treatment system that allows water to co-mingle with any other water feature other than a pool as defined in Subchapter L, §265.182 of this title.
