Upgraded G52 Relief Valve Replacement Compatible with Zodiac 180 280 380 480 3900 Pool Cleaners (1PC)

[PERFECT FIT]: The G52 Polaris backup valve replacement kit is a perfect fit for Zodiac Polaris 180, 280, 380, 480 PRO, 3900 Sport, Vac-Sweep 380, Vac-Sweep 280, and 280 TankTrax models. [IMPROVED QUALITY]: The new G52 Polaris 280 backup valve mechanism is made from an improved blend of crack-resistant polymers, which are more abrasion-resistant and less likely to be damaged. It can operate continuously under ultra-high water pressure. NOTE: If the gears become stuck in the sand, you will need to remove the grinding wheel, clean the sand, and continue working. [EASY TO USE]: No assembly required. The G52 emergency valve is ready to install; simply connect the fittings and hoses securely to operate. It opens every 3 minutes for 30 seconds to remove the cleaner by changing its cleaning direction. This valve can also pull the unit out of tight spaces if it gets stuck. [WHEN TO REPLACE]: When the Polaris 280/380 pool rear seat valve cleaner gets caught on an obstacle or edge, or even when the emergency valve is still open but the nozzle is no longer spraying water, you should consider checking or replacing it. The Covienapp G52 emergency valve solves this problem.
