Winterizer Valves

Winterizer Valves

Winterizer valves are seasonal shutoff and drain valves used to prepare plumbing, irrigation, and outdoor water systems for freezing conditions. These valves allow water supply lines to be isolated and fully drained to prevent pipe bursts, fixture damage, and system failures caused by ice expansion. Commonly used in irrigation systems, hose bibb lines, landscape water systems, and seasonal buildings, winterizer valves are typically installed at low points or system entry points to facilitate complete drainage. Available in ball-type, multi-port, and manual drain configurations, these valves support residential, commercial, agricultural, and municipal winterization procedures.
