Good To Know

Q: How often should I replace the pressure gauge and relief valve assembly? A: Replace the assembly if the gauge needle sticks, the lens is fogged, or the relief valve drips continuously. Jandy recommends inspecting it whenever you perform filter maintenance.

Q: Does this assembly fit older Jandy filters? A: It fits most Jandy CV, CL, and DEV filters manufactured after 2000, but always verify the thread size and part number R0357200 against your original unit before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
