I have a field-fabricated, unblockable drain cover that I believe meets the current ASME/ANSI standard. Am I required to order a new cover?
No. A field-fabricated cover may continue to be used where a professional engineer (PE) certifies that it meets the requirements of ASME/ANSI A112.19.8-2007, including flow rates, UV exposure, and durability. The PE must document that the drain cover meets the new standard and provide a copy of the certificate to the pool owner/operator.
