INSTALLATION & USE
How to Install the VV-WWC-14 Feed Adapter
- Shut off the cold water supply and drain the line. Thread the 1/2" MNPT end into your existing cold water supply line using thread sealant or PTFE tape.
- Connect your fixture or appliance to the 1/2" FNPT outlet on the opposite end, maintaining inline flow through the adapter.
- Thread your 1/4" feed water valve or compression fitting (such as the Watts VV-TKB14) into the side 1/4" FNPT port for your RO system or filter connection.
- Restore water pressure slowly and inspect all three connection points for leaks. Tighten connections as needed, but avoid overtightening chrome fittings.
COMPATIBILITY
Works With Your System
The VV-WWC-14 chrome feed adapter is designed for use with residential and light commercial reverse osmosis systems, under-sink carbon filtration units, and UV sterilization equipment requiring a 1/4" feed water connection. It pairs directly with the Watts VV-TKB14 ball valve and works with any system using standard 1/4" OD tubing. Ideal for installations where copper saddle valves are not preferred or where local codes require inline tee connections instead of piercing-style fittings.
🔧 Pro Tip: Install this adapter horizontally with the 1/4" feed port facing down to keep air bubbles from collecting in the tee. Use a second wrench to back-hold the adapter body when tightening your feed valve to prevent loosening the main inline connections.
