Oatey Co.’s updated Drain Seal blocks unwanted odors, sewer gases and insects from entering a building through a drain with an enhanced design that won’t restrict water flow or sacrifice performance, the company notes. It’s engineered with a drainage system that prevents water from evaporating in the P-trap, and allows for continuous water flow, which inhibits ponding or pooling around a drain. Available in 2" or 3" sizes. www.oatey.com
