The WATTS 390 802 is a replacement plunger kit designed for use in valve assemblies within plumbing systems. This kit supplies the plunger component necessary to restore proper valve function when the original part has worn or failed. Plunger kits of this type are commonly installed by licensed plumbers during routine maintenance or service calls. The kit provides the core moving element that controls flow or pressure within the valve body, making it a critical repair component when restoring a valve to full working order.
This plunger kit is suited for repair and maintenance applications in residential and light commercial plumbing installations. It is used when a valve plunger shows signs of wear, damage, or failure that affect shutoff performance or flow control. Installation is straightforward for technicians already familiar with the parent valve assembly.
Designed as an OEM-style replacement plunger kit for WATTS plumbing valve assemblies requiring plunger service.
Installation should be performed by a licensed plumber in accordance with applicable IPC requirements. Shut off the water supply and relieve system pressure completely before disassembling the valve body. Inspect the valve seat and seals during service and replace any additional worn components before reassembly. Restore supply pressure gradually after installation and verify there are no leaks before returning the system to normal operation.
