Installation Instructions

Follow these steps for a quick and easy installation of your new Fluidmaster 703AP4 fill valve.

1. Turn off Water Supply: Locate the water supply valve behind or near the toilet and turn it clockwise until the water flow stops. Flush the toilet to empty the tank.
2. Remove Old Fill Valve: Disconnect the water supply line from the bottom of the old fill valve. Unscrew the mounting nut holding the old fill valve in place and carefully remove it from the tank.
3. Clean Tank Base: Clean any debris or mineral buildup from the hole at the bottom of the toilet tank where the fill valve sits.
4. Install New Fill Valve: Insert the new Fluidmaster 703AP4 fill valve into the hole at the bottom of the tank. Ensure the shank washer is properly seated on the outside of the tank.
5. Secure Fill Valve: Hand-tighten the mounting nut onto the threaded shank of the new fill valve from underneath the tank. Do not overtighten.
6. Connect Water Supply: 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.
7. Turn on Water Supply: Slowly turn the water supply valve counter-clockwise to restore water flow to the toilet tank. Check for leaks.
8. Adjust Water Level (if necessary): The valve is designed to optimize refill. If adjustment is needed, refer to the diagram below for components like the shock nut and flow regulator.

Operating Instructions

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.

Maintenance

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.

Replacing Seal and Rinsing Out Debris:

Refer to the diagram in the Installation section (Image: Diagram for replacing Fluidmaster 703A5B fill valve) for visual guidance.

1. Turn off Water: Turn off the water supply to the toilet.

3. Remove Float Arm: Remove the float arm assembly from the valve body.
4. Rinse Debris: Place a cup over the top of the valve and turn on the water supply for several seconds to flush out any debris.
5. Inspect Seal: Inspect the disc shut-off seal for any damage or wear. Replace if necessary.
6. Reassemble: Reinsert the float arm and turn the valve top clockwise to lock it back into place. Ensure the side bubbler is set horizontally.
