Underground Lawn Sprinklers / Irrigation Systems
The City of Killeen requires all underground lawn sprinkler / irrigation systems to have either a pressure vacuum breaker (PVB) or a reduced pressure zone assembly (RPZ) on all new installations. If there is an old double check in place, it is acceptable as long as it passes the test, once if fails or needs repair, it must be replaced with a PVB-where applicable or an RPZ. City code prohibits any type of cross connection which could endanger the water system.
