This Waterway 90 Degree High Flo Spa Suction assembly has a higher rating of 128 GPM for use in self contained portable spas. The new design is complaint with the Virginia Graeme Baker Act, VB 2008, and ASMEA112.19.8-2007.
This suction requires a 2-1/2� hole in the spa shell when installed with grommet gasket or 2-3/8" hole with a flat gasket. The 90 Degree Hi-Flo Spa Section has a 1.5" slip plumbing connection.
It is a great replacement for many older spa suctions that are not VGB/ ASMEA112.19.8-2007 approved.
