Yes, in most cases, you will need a backflow preventer connected to your sprinkler system. Backflow preventers, like those available at Watts, protect your home’s drinking water from contaminated or non-potable water. Irrigation systems are one of the most common sources of potential cross-contamination, so most plumbing codes require a backflow preventer. Feel free to order one of the Watts backflow preventers on this page, or one of the other backflow preventers available at Sprinkler Warehouses.

A PVB vent float kit is a repair kit for the internal vent float assembly in a pressure vacuum breaker. The vent float and its associated parts are what allow the PVB to open to air and break a vacuum when supply pressure drops, preventing contaminated irrigation water from being drawn back into your potable water supply. These kits are designed to replace worn or damaged internal parts that control the PVB’s ability to vent air and stop back-siphonage.
