CPSC staff supports the technical requirement of the ANSI/ASME A112.19.8 performance standard, or the successor standard ANSI/APSP-16 2011 performance standard, which calls for field-built sumps to have a depth, when measured from the bottom of the cover to the top of the outlet piping, of 1.5 times the diameter of the piping.

  • The P&SS Act does not require pool owners/operators to replace their sump. If a new, compliant drain cover can be safely secured onto a preexisting sump, while properly controlling the flow rate, then it meets the intent of the law.
  • If a professional engineer (PE) determines that additional engineering work needs to be done to the sump to bring it into compliance with the standard and ensure a secure connection with a new cover, then that work should be carried out.
  • If a PE determines that a new drain cover cannot be safely placed on a pre-existing sump, then the sump should be removed and replaced with a new, compliant sump that is compatible with the compliant drain cover.
