Abstract

According to the present invention, water regulation assemblies disposed in the water supply path of conventional fixtures are modified to include a pressure relief assembly which permits release of water under elevated pressures. A normal shut-off seal included in the water regulation assembly is modified to release water in response to elevated pressure even when the seal is placed in a shut-off position. This permits relief of elevated pressure in water supply lines which might otherwise produce a burst event within the water supply lines. Preferred modified shut-off seals include a washer having soft portions which deform to permit pressure relief by release of water past the shut-off seal in response to elevated pressure and a gasket including a region of reduced thickness which deforms in response to elevated water supply pressure thereby releasing water into the socket and relieving water supply line pressure.
