Setup and Installation
Before you begin, ensure you have the necessary tools: adjustable wrench, sponge, and bucket.
- Turn off Water Supply: Locate the water supply valve at the base of the toilet and turn it clockwise until the water flow stops completely.
- Flush Toilet: Flush the toilet to drain most of the water from the tank. Use a sponge to remove any remaining water.
- Disconnect Water Supply Line: Unscrew the water supply line from the bottom of the old fill valve. A bucket may be needed to catch any residual water.
- Remove Old Fill Valve: Loosen the lock nut on the underside of the toilet tank that secures the old fill valve. Remove the old fill valve from the tank.
- Install New Fill Valve: Insert the Danco Hydroclean HC660 fill valve into the hole at the bottom of the toilet tank. Ensure the shank washer is properly seated.
- Secure Fill Valve: From the underside of the tank, hand-tighten the new lock nut onto the fill valve shank. Do not overtighten.
- Connect Water Supply Line: Reconnect the water supply line to the new fill valve's shank. Hand-tighten, then use an adjustable wrench for a final quarter-turn. Do not overtighten.
- Attach Refill Tube: Connect the refill tube from the fill valve to the overflow pipe in the toilet tank. Ensure it is securely attached and positioned above the water level.
- Turn on Water Supply: Slowly turn the water supply valve counter-clockwise to restore water flow to the toilet tank. Check for leaks.
- Adjust Water Level: The Hydroclean HC660 allows for water level adjustment. Refer to the "Operating" section for instructions on how to set the desired water level.
Operating Instructions
The Danco Hydroclean HC660 fill valve is designed to efficiently refill your toilet tank after each flush and automatically shut off when the desired water level is reached.
Adjusting Water Level:
To adjust the water level in the toilet tank:
- Locate the water level adjustment mechanism on the fill valve. This typically involves a float or a screw adjustment.
- For most Hydroclean models, gently twist the top cap or slide the float mechanism up or down to raise or lower the water level.
- Flush the toilet after each adjustment to observe the new water level. Repeat until the desired water level is achieved, typically about 1 inch below the top of the overflow pipe.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your Danco Hydroclean HC660 fill valve.
Cleaning the Fill Valve:
Over time, mineral deposits or debris can affect the valve's operation. To clean:
- Turn off the water supply to the toilet.
- Flush the toilet to drain the tank.
- Carefully remove the top cap of the fill valve (refer to specific model instructions if needed).
- Inspect the rubber seal (diaphragm) and the valve seat for any debris or mineral buildup.
- Rinse components under clean water. Use a soft brush if necessary to remove stubborn deposits. Avoid harsh chemicals.
- Reassemble the valve, ensuring all parts are correctly seated.
- Turn on the water supply and check for proper operation and leaks.
Leak Checks:
Periodically check for leaks around the base of the fill valve and the water supply line connection. Tighten connections if necessary, but do not overtighten.
