The requirements for anti-drowning drain covers are intended to keep children from getting sucked onto pool and spa drains under water.
Congress passed a law last year requiring the new equipment and gave pool and spa operators a year to comply.
Nancy Nord, acting chairman of the Consumer Product Safety Commission, says the government will focus first on swimming sites that pose the greatest risk to children. Those include public baby pools and wading pools specifically designed for small children, as well as in-ground spas.
Nord says Congress didn't give her agency any extra money to enforce the law.
