The 256 GPM, 179 GPM and the 124 GPM suction fitting that meets the Virginia
Graeme Baker
Pool and Spa Safety Act of 2008. The patented 256 GPM flow
rated suction fitting has received
UL approval, while the 124 GPM
suction is IAPMO listed with a flow rating of 124 GPM.
The extraordinary
rating on both suctions is higher than any other equivalent sized
suction
on the market prior to the VGB legislation.
The large 256 GPM and 179 GPM suction is about 5 inches (12.7cm) in diameter
and the
124 GPM is about 3-3/4 inches (9.53cm) in diameter. The
smaller size fits the smaller recesses
by reducing the need to modify
any molds in order to make the larger suction fit. The smaller
hole has a
size of 2-3/8 inches (6.03cm) with a flat gasket.
The 256 GPM suction requires an intermediary vacuum break piece that connects to 3/4” (1.9cm)
ID tubing,while the smaller 124 GPM suction product connects to 3/8” (.95cm).
The tubing should be
positioned to rise up under the lip of the spa. When the suction cover is obstructed, air is pulled
through the tubing, cavitating the pump so it loses prime and water flow is minimized.
Balboa Water Group's VGB suctions are patented under U.S. Patent No. 8,191,183.
