Caretaker WK000036 Revolution 6-Port Valve Pre-Plumbing Kit for Jandy pool cleaners. It is engineered for cost-saving cleaning that maximizes water flow even at low pump speeds. With a leak-free design offering unsurpassed efficiency and durability, it’s the only in-floor cleaning valve with an unimpeded 2-inch port and an innovative QuickFlow™ Shifting System that maximizes the duration of full cleaning pressure to each zone for superior cleaning results. Constructed for long-term, reliable operation, the Jandy Revolution Valve performs equally under low-and high-pressure conditions while preventing “dead head” from occurring and damaging the pump and features an easy-to-service one-piece gear cartridge that can readily be swapped out if needed.
