Product Overview

Provide a residential outdoor watering connection with automatic drainage after shutoff. The W-style inlet fits a half-inch Wirsbo expansion PEX supply. The Prier C-434W uses a self-draining bypass and double-check protection. Choose the insertion length that places the shutoff in heated space; the drain system still depends on correct orientation and installation.
