Frequently Asked Questions

Q: What is a brass automatic float valve used for?

A: A brass automatic float valve is used to automatically release trapped air from plumbing systems such as radiators, heating pipelines, water tanks, and irrigation lines. The float mechanism opens to vent air and closes once water fills the chamber, preventing airlocks and maintaining efficient water flow without any manual effort.

Q: What thread size does this float valve kit use?

A: This kit uses a standard 1/2" G (BSP – British Standard Pipe) thread, making it compatible with most common household and commercial plumbing fittings. The included female connector adapter ensures a secure, leak-free connection.

Q: Does this valve require electricity to operate?

A: No — this brass automatic float valve is entirely electricity-free. It operates purely on a mechanical float/needle principle, making it ideal for remote installations, outdoor systems, or anywhere a reliable, power-free solution is needed.

Q: Is this valve suitable for both hot and cold water systems?

A: Yes. The solid brass construction makes this valve suitable for use in both hot and cold water plumbing systems, including central heating radiators and general water supply lines. Always verify your system's specific pressure and temperature ratings before installation.
