Couple questions about "divert to drain" capability of an RO: 1. Is this a requirement and if so where does it say this? 2. If your existing RO never had one do you need to retrofit the RO or are you grandfathered? thanks
AAMI RD62 says "In addition, it is recommended that when a reverse osmosis system is the last process in the water treatment system used to remove chemical contaminants, it includes a means to prevent patient exposure to unsafe product water, such as diversion of the product water to drain, in the event of a product water conductivity or rejection alarm." The appendix goes on to further say that this is a "recommendation" and "with direct feed water distribution systems, a divert-to-drain would cause an immediate alarm condition with all dialysis machines as a result of interrupting their water supply. Under such circumstances, the ability to discontinue dialysis electively may pose the least risk to the patients. Therefore, a divert-to-drain was included as a recommendation and not as a requirement."
Divert to drain is a good idea but not required. You are not required to retrofit your RO.
