If a pool
or spa has TWO (2) main drains what do I need to
do to comply with VGB?
If the main drains are at least 3'
apart (from edge to edge, not center to center)
then You must install a grates that meets the
latest ASME standard by December 19, 2008. If the
main drains are not 3' apart then you should treat
the application similar to a single main drain and
install an anti-entrapment device such as an SVRS. |
