- Secure Fill Valve: Hand-tighten the mounting nut onto the threaded shank of the new fill valve from underneath the tank. Do not overtighten.
- 물 공급 연결: Reconnect the water supply line to the bottom of the new fill valve. Hand-tighten, then use a wrench to tighten an additional quarter turn. Do not overtighten.
- 물 공급을 켜세요: Slowly turn the water supply valve counter-clockwise to restore water flow to the toilet tank. Check for leaks.

작동 지침
The Fluidmaster 703AP4 fill valve operates automatically to refill your toilet tank after each flush. Once installed, it will maintain the proper water level for optimal flushing performance.
- After flushing, the water level in the tank will drop, causing the fill valve to activate.
- The valve will quickly refill the tank to the predetermined water line.
- Once the desired water level is reached, the valve will automatically shut off the water flow.
유지
Regular maintenance can extend the life of your fill valve and ensure optimal performance. If you notice slow refilling or continuous running, the valve may need cleaning.
