Product Information
Full details
The Excel Home Brass Ball-Cock Float Valve is an essential plumbing component for homeowners and professional tradespeople needing reliable water level control in cisterns, water tanks, and troughs. Its primary strength lies in its durable brass construction and BS1212-compliant design, which ensures long-term consistency and resistance to wear. However, users should note that as a mechanical float system, it requires periodic inspection to ensure the moving arm remains clear of debris and mineral buildup for optimal functionality.

FAQs
Is this valve suitable for high-pressure water mains?
This valve is designed for standard water systems; ensure your specific tank pressure does not exceed the manufacturer's recommended limits for BS1212 parts.
Can I use this for hot water tanks?
This model is primarily designed for cold water cisterns and troughs; check local plumbing regulations before using in hot water applications.
What size is the inlet connection?
The valve features a standard 1/2 inch connection.
Is the float ball included?
Yes, the product includes a plastic ball float designed to pair with the brass valve arm.
How do I prevent the arm from corroding?
The arm is made of high-quality brass which is inherently resistant to corrosion, but regular cleaning to remove mineral deposits will keep it moving smoothly.
Troubleshooting
Water continues to run after the tank is full
Adjust the float arm downward to ensure the valve closes earlier or check if the washer inside the valve seat is worn and needs replacement.
Water level is too low
Gently bend the brass arm upward to allow the tank to fill to a higher level before the float triggers the shut-off mechanism.
Leaking at the tank connection point
Ensure the locknut is tightened firmly and verify that sufficient plumbing thread seal tape was applied during installation.

Setup, Compatibility & Care
To install, ensure the water supply is turned off completely. Thread the 1/2 inch valve into your tank inlet using an appropriate sealant or tape to prevent leaks. Once secured, attach the float to the threaded end of the arm. After the system is pressurized, test the water level by slightly bending the brass arm until the desired cut-off height is reached.
To maintain the unit, check the arm for mineral deposits annually if you reside in a hard-water area. If the valve fails to seal, inspect the seat and washer for sediment buildup and clean as necessary. Never use harsh chemical cleaners on the brass body, as these may damage the integrity of the threads.
