The vacuum lock is installed on the suction side of the piping system and helps create a seal between the vacuum line and the pool wall joint, allowing the vacuum to operate efficiently. It is a safety mechanism designed with a spring-action cover that holds the pool cleaner hose in place and automatically snaps on the suction fitting when not in use
Never operate the pool without covering the suction port or vacuum port
