Installation Guide for Double Corner Valve

A double corner valve is a uniquely designed component featuring two outlets, allowing simultaneous connections to two appliances (e.g., a toilet and a washbasin) while providing independent control over each water flow. Due to its multifunctional design, double corner valves are widely used in residential and commercial water supply systems. Proper installation is essential to ensure stable operation and prevent leaks. Below is a step-by-step guide for installing a double corner valve correctly.

1. Preparation Before Installation

Before installing a double corner valve, gather the necessary tools and materials:

• Wrench (an adjustable wrench is recommended for different connection sizes)
• PTFE tape (thread seal tape) (to enhance sealing on threaded connections)
• Screwdriver (for securing screws on some valve models)
• Cleaning cloth (to wipe the connection points)

Additionally, check whether the double corner valve matches the pipe size for a secure and proper installation. Chinese faucet factories manufacture double corner valves with standardized interfaces, ensuring compatibility with various water supply systems.

2. Shut Off the Water Supply

Before installation, turn off the main water supply to prevent uncontrolled water flow. After shutting off the water, open a nearby faucet or appliance to release any residual pressure in the pipes, ensuring a dry and manageable working environment.

3. Thread Sealing Treatment

To improve the sealing effect, apply 3-5 wraps of PTFE tape around the threaded connections of the double corner valve in a clockwise direction. This prevents leaks and ensures a tight fit. Chinese faucet factories use precision-threaded designs to enhance connection stability, but additional sealing tape can further improve leak prevention.

4. Connecting the Double Corner Valve

Use a wrench to screw the double corner valve into the wall-mounted water supply pipe in a clockwise direction. Tighten it with moderate force to secure the connection while avoiding excessive pressure that could damage the threads or deform the valve body. Ensure that the two outlets are positioned correctly to facilitate smooth connections to the appliances.

5. Connecting Water Appliances

Once installed, connect the double corner valve to the two water appliances (e.g., a toilet and washbasin, or a washing machine and water heater). When attaching the hoses, ensure that the threaded connections align properly and apply additional PTFE tape if needed to improve the seal and prevent leaks.

6. Turn On the Water Supply and Inspect

After completing all connections, slowly turn on the main water valve and allow water to flow into the system. Inspect the double corner valve for any leaks and test the functionality of both outlets separately. Each outlet should operate independently. If any leaks or dripping occur, adjust the threading or replace the sealing ring to resolve the issue. Chinese faucet factories conduct strict quality tests on double corner valves, ensuring excellent sealing and stability even under high water pressure.

7. Regular Inspection and Maintenance

After installation, periodically check the double corner valve for leaks, clean the surface, and ensure smooth operation. Since a double corner valve controls two outlets, avoid excessive force when operating the handles to prevent damage to the valve core or sealing components. Chinese faucet factories manufacture double corner valves with premium materials, ensuring long-lasting durability and reduced maintenance costs.

Conclusion

Proper installation of a double corner valve improves the stability of the water supply system, minimizes leakage risks, and extends the product’s lifespan. Choosing a double corner valve from Chinese faucet factories guarantees superior sealing performance and meets the high-quality standards required for modern residential and commercial plumbing systems. By following the correct installation procedures, users can ensure efficient and long-term operation of double corner valves in any water supply system.
