Frequently Asked Questions

Q: What does G1/2 (4 Points) mean, and will this valve fit my toilet or faucet?

A: G1/2 refers to the British Standard Pipe (BSP) thread size, commonly called "4 Points" in plumbing. It is the most widely used water supply connection size for toilets, bathroom sink faucets, bidets, and washing machines in many countries. Check your existing supply line or valve thread size before purchasing — if it's currently G1/2 or DN15, this valve will fit perfectly.

Q: Is this brass triangle valve suitable for hot water lines such as water heaters?

A: Yes. The solid brass body of this stop valve is compatible with both cold and hot water supply lines, making it suitable for use with water heaters as well as standard cold-water toilet and sink connections. Always verify the temperature rating does not exceed your heater's output specifications.

Q: How do I prevent leaks when installing this stop valve?

A: For best results, wrap the threaded connections with 2–3 layers of PTFE (plumber's) tape before threading the valve into place. Hand-tighten first, then use an adjustable wrench for a snug (not excessive) final turn. After installation, slowly restore water pressure and inspect all joints for drips before considering the job complete.

Q: Can this valve be used for a washing machine water supply?

A: Absolutely. This universal G1/2 triangle stop valve is designed for multi-application use, including washing machine inlet connections. Its quarter-turn lever makes it convenient to shut off water supply to your washing machine quickly when needed.
