This Waterway Ultra High Flo Spa Suction assembly is rated at 160 GPM (for wall use only). This is for use in self contained portable spas only. This is a new design spa suction complaint with the Virginia Graeme Baker Act, VB 2008, and ASMEA112.19.8-2007.
This suction is designed to use a 2-1/2 inch hole in the spa shell with a Grommet gasket and 2-3/8" hole in the spa shell with a flat gasket. This Ultra Hi-Flo Spa Section has a 1.5" Slip Plumbing connection.
The Waterway Ultra Hi-Flo suction is great for self contained portable spa applications where you need a little extra flow but a small wall footprint.
