Watts (1R-1Y) Kwik-Change WQC4RO11 Bi-Annual Replacement Filter Kit
Watts (1R-1Y) WQC4RO11 Bi-Annual Replacement Filter Kit
This Watts bi-annual replacement kit pairs the WQCSC11 sediment filter (5 micron) with the WQCCC11 carbon block filter (10 micron) to maintain consistent performance in your Kwik-Change system. The proprietary quarter-turn design and internal shut-off valves make filter replacement a clean, simple process every six months without tools or system depressurization.
What's Included in Your Replacement Set
WQCSC11 Sediment Filter
Removes dirt, rust, and sediment at 5 micron nominal. First-stage protection for membrane and carbon media.
WQCCC11 Carbon Block
Removes chlorine, taste, and odor at 10 micron nominal. Pre-treatment for RO membranes or standalone polishing.
Quarter-Turn Connection
Watts Kwik-Change cartridges install and remove with a simple 1/4 turn. No wrenches, no thread sealant, no mess.
Dual O-Ring Seal
Double O-ring design eliminates leaks. Internal valves shut off water flow automatically when cartridges are removed.
11-Inch Proprietary Size
Standard 11" length for Watts Kwik-Change housings. Not compatible with standard 10" cartridge housings.
6-Month Replacement Cycle
Designed for bi-annual replacement. Does not include RO membrane, which operates on a separate service schedule.
System Compatibility
This kit is designed for Watts Kwik-Change reverse osmosis systems and whole-house filtration systems that use the proprietary 11-inch Kwik-Change cartridge format. Compatible with Watts model 1R-1Y systems and other Kwik-Change configurations requiring WQCSC11 sediment and WQCCC11 carbon block filters. Verify your existing cartridge model numbers before ordering. This is a pre-filter set and does not include the RO membrane element.
Watts Kwik-Change filters are engineered for residential and light commercial applications where consistent water quality and fast maintenance matter.
