SureSeal

SureSeal is a line of waterless trap seal devices manufactured by RectorSeal, a supplier of plumbing and HVAC specialty products. The product line addresses a common problem in commercial and institutional buildings: floor drains that dry out from infrequent use, allowing sewer gas and odors to escape into occupied spaces. RectorSeal markets SureSeal as an alternative to water based trap primers, relying on a mechanical seal rather than a continuous water supply.

Product Lines

The SureSeal lineup centers on inline and floor drain trap seals available in multiple pipe diameters to match common drain configurations. Devices use a patented memory hinge along with a pressure relief valve, designed to open under flow and reseal once water has drained. Several SureSeal models carry ASSE 1072 approval, the industry standard covering trap seal protection devices.

Why Contractors Specify SureSeal

Plumbers working on commercial retrofits often choose SureSeal because the device eliminates the need to run a water line to a trap primer, simplifying installation in drains that are difficult to access. Because the seal operates mechanically rather than relying on a metered water supply, maintenance teams spend less time troubleshooting primer valves or chasing intermittent odor complaints. The pressure relief valve design also helps the device hold up under repeated drainage cycles in high traffic floor drains such as those found in parking garages, mechanical rooms, and food service areas.

How to Choose SureSeal Products

Selecting the correct SureSeal model starts with measuring the existing drain pipe diameter, since devices are sized to specific inline and floor drain dimensions. Installers should confirm whether a drain is rarely used, since that is the primary condition SureSeal is designed to address, rather than drains with regular flow that maintain a natural water seal. For code compliance documentation, specifiers can reference the ASSE 1072 listing on the applicable model.

Frequently Asked Questions

What does a SureSeal trap seal device actually do?

It keeps a mechanical seal in place over an infrequently used floor or inline drain, blocking sewer gas and odors from entering the building when the natural water trap would otherwise evaporate.

Does SureSeal require a water supply line?

No. The device relies on a mechanical memory hinge and pressure relief valve rather than a connection to a water source, which is one of the main differences from trap primer systems.

How do installers know which size SureSeal to order?

Match the device to the inside diameter of the drain pipe; SureSeal trap seals are manufactured in multiple sizes to fit standard floor and inline drain dimensions.

Is SureSeal approved for commercial plumbing code compliance?

Several SureSeal models hold ASSE 1072 approval, the recognized standard for trap seal protection devices, which inspectors commonly reference during plan review.

Where are SureSeal devices typically installed?

Common applications include floor drains in parking garages, mechanical rooms, and food service or institutional kitchens where drains see infrequent or seasonal use.
