Product details

The AquaStar 620SI103 is a light gray 6 inch sumpless bulkhead fitting with a 2 inch slip insider connection, for single or multiple drain use in pools and spas.

What it does

A bulkhead fitting connects a suction outlet to the pool plumbing through the pool shell. This one is sumpless, so it needs no separate sump, and it has an 11.4 square inch opening. The pipe connection is a 2 in. slip insider.

Fit and compatibility

AquaStar designs it for gunite, steel, vinyl, fiberglass and tile pools and spas; see the installation instructions for your pool type. Flow ratings are 224 GPM at 6.3 fps on a 2 in. floor or wall pipe, 177 GPM at 5.9 fps on a 1-1/2 in. floor pipe and 122 GPM at 3.4 fps on a 1-1/2 in. wall pipe.

Choosing the right fitting

The last three digits of an AquaStar part number are the color number, so 103 is light gray and the same fitting in white is 620SI101. If your plumbing is 1-1/2 in., the bulkhead is also made with a 1-1/2 in. slip insider as part number 615SIxxx. Eight adapter plates for other connection types are sold separately. AquaStar states that the fitting meets or exceeds ANSI/APSP 16-2011 and NSF 50-2008.
