Description
The Swimables SW-32-340 black spa check valve is an essential flow-control component built to keep water traveling in the correct direction within your spa or hot tub plumbing. Equipped with a 1.5-inch male pipe thread (MPT) fitting, it threads directly into standard spa plumbing lines for a watertight connection. Inside, a precision spring-loaded gate driven by a 316 stainless steel pin and spring responds instantly to pressure changes, snapping shut the moment flow reverses. The valve body is made from tough, chemically inert materials that won’t degrade when exposed to sanitizers, pH adjusters, or heated spa water. Straightforward thread-in installation means you can have it operational in minutes, restoring proper circulation and protecting pumps, heaters, and jets from the damaging effects of backflow.
