1. Product Overview

The Duravit 0074030062 Metro Flush Valve is an essential component for your toilet's flushing mechanism. This is an original replacement part designed for Duravit Metro toilets, featuring a 3-inch one-piece design and engineered for a single flush at 1.28 gallons per flush (gpf). It ensures efficient and reliable water discharge from the toilet tank into the bowl.

2. Installation (Setup)

2.1 Safety Precautions

• Always turn off the water supply to the toilet before beginning any installation or maintenance.
• Drain the toilet tank completely before removing old components.
• Wear appropriate personal protective equipment, such as gloves, if necessary.

2.2 Tools Required

• Adjustable wrench or pliers
• Sponge or towel for water cleanup
• Bucket (optional, for draining)

2.3 Installation Steps

1. Turn off the water supply valve located at the base of the toilet.
2. Flush the toilet to drain most of the water from the tank. Use a sponge or towel to remove any remaining water.
3. Disconnect the old flush valve from the toilet tank. This typically involves unscrewing a large nut from underneath the tank and detaching the refill tube and flush lever chain.
4. Clean the area where the flush valve seats to ensure a proper seal.
5. Place the new Duravit 0074030062 flush valve into the opening at the bottom of the tank, ensuring the gasket is properly seated.
6. From underneath the tank, secure the flush valve with the large mounting nut, tightening it firmly but without overtightening to avoid cracking the tank.
7. Connect the refill tube to the overflow pipe of the new flush valve.
8. Attach the flush lever chain to the flapper arm, ensuring there is a slight amount of slack (approximately 1/2 inch) when the flapper is closed. Too much tension will prevent a proper seal, and too much slack will prevent a full flush.
9. Turn the water supply back on and allow the tank to fill.
10. Check for any leaks around the base of the flush valve and the water supply connection.
11. Perform several test flushes to ensure proper operation and water level.

3. Operating Instructions

The Duravit 0074030062 Metro Flush Valve is designed for single-flush operation at 1.28 gpf. To operate, simply press or push the toilet's flush lever. This action lifts the flapper, allowing water to flow from the tank into the toilet bowl, initiating the flush cycle. Once the tank is empty, the flapper will return to its closed position, and the tank will begin to refill.

4. Maintenance

Regular maintenance helps ensure the longevity and efficient operation of your flush valve.

• Cleaning: Periodically inspect the flapper and the flush valve seat for mineral deposits or debris. Clean with a soft brush and mild, non-abrasive cleaner if necessary. Avoid harsh chemicals that can damage rubber components.
• Flapper Inspection: Check the flapper for signs of wear, cracking, or stiffness. A worn flapper can lead to continuous running water. Replace the flapper if it appears damaged or is not sealing properly.
• Chain Adjustment: Ensure the flush chain has the correct amount of slack. Too tight, and the flapper won't seal; too loose, and it won't lift fully. Adjust as needed.
• Leak Checks: Regularly check for leaks around the base of the toilet and inside the tank. A small amount of food coloring in the tank can help identify slow leaks past the flapper if the color appears in the bowl without flushing.
