Super Sump
(Patent Pending # US11-207153)

The First All-in-One Sump!

Finally, a sump that's 1/3 of the cost of fiberglass and 1/4 of the cost of stainless! Grate Technologies does it again—inventing an all-in-one main drain and sump—Super Sump™. With the highest flow rate for maximum efficiency, it includes everything you need!

Super Sump design features include:

• Open grate area of 57% — allowing a flow rate of 800 GPM at 1.5 ft. per second.
• Internal plumbing fittings instead of external. Allows stacking and avoids breaking off or cracking during shipment, pressure testing or handling.
• Unique built-in water stop with two vertical extensions. Prevents water passing over the flange.
• Includes hydrostatic relief valve, collector tube with holes and extension tubes.
• A solid one-piece, injection-molded unit. Less expensive than fabricated PVC sheets, stainless steel or fiberglass.
• Tapered body for strength — allows for water expansion during freezing, and easily stacks to reduce storage space and shipping costs.

Super Sump's Grate Design Exceeds All Expectations!
(Patent Pending # US11/633064)

An open area of 57% allowing a flow rate of 800 GPM at 1.5 ft per second. A complete, molded unit with additional iternal depth for increased strength. A raised cross-ridged profile for non-slip—and water penetration if blocked.
