12 Inch Square SuperSump Main Drain Sump With 6 Inch Port (Pack of 2)

Description

This is a package of two 12 inch Square SuperSump Main Drain Sumps with 6 inch port. They have an open area of 81.30 square inches and 365 GPM Floor. The Neptune Benson (Evoqua) SuperFlow Sumps are ASME-2007 and NSF listed. The SuperSump main drain system eliminates the need for certification of field-formed sumps by a licensed design professional. The SuperSump with SuperFlow main drain grating is pre-certified which allows you to move forward with construction and avoid the unnecessary delay of field inspection and concrete sumps. Add to this the highest flow rate for maximum efficiency, a long list of benefits and advantages, and you have a main drain system that will give you peace of mind.

The SuperSump Main Drain System features a unique built-in water stop with two vertical extensions. This prevents water passing over the flange. They also have internal plumbing fittings instead of external. This allows stacking and avoids breaking off or cracking during shipment, pressure testing or handling.

The SuperSumps are a solid, injection molded unit which is less expensive than stainless steel or fiberglass. They have a tapered body for strength and durability. It allows for water expansion during freezing.

Hydrostatic relief valves and collector tubes are sold separately. Two hydrostatic relief valves per sump are required (see #170SP-10560). Four collector tubes are required per sump (see #170SP-1055). Evoqua offers a variety of main drain solutions in order to meet the Virginia Graeme Baker Pool and Spa Safety Act starting in 2008. NSF tested and ASME LISTED, SuperFlow grates are the only choice for retrofitting your main drains or constructing your new pool.
