The Consumer Product Safety Commission is extending by one year the deadline for retrofitting unblockable drains in public pools.

In 2010, the CPSC determined that an unblockable drain cover could be installed over a smaller sump to comply with the Virginia Graeme Baker Act. But last September, the group reversed itself, requiring that the sumps also meet certain dimensional and flow criteria. The CPSC mandated retrofits on those drains that fell out of the unblockable category, and set a deadline of May 28, 2012 for compliance. Officials said a later date could be considered based on public comments.

Last week, staff recommended to the four sitting Commissioners that the deadline be extended to May 23, 2013, the Thursday before Memorial Day.
