Frequently Asked Questions

Q: What sizes are included in this 3-pack of stainless steel float valves?

A: The pack includes float valves in both 1/2" and 3/4" thread sizes, making it versatile enough to fit a wide variety of tanks, cisterns, and plumbing fittings. Having multiple sizes ensures you're covered for different setups or replacement needs.

Q: Why is a ceramic valve core better than a rubber valve core?

A: Ceramic valve cores offer superior durability and longevity compared to traditional rubber cores. They resist wear, mineral buildup, and degradation over time, providing a more consistent seal and smoother water flow throughout their lifespan.

Q: Can these float valves be used for potable (drinking) water tanks?

A: Yes. These valves are constructed from 304 stainless steel and are free from high-concern chemicals, making them suitable for use in potable water storage tanks. Always ensure your full plumbing system complies with local water safety regulations.

Q: How does the automatic float valve work?

A: The float valve uses a buoyant float arm that rises with the water level. Once the water reaches the preset level, the float automatically shuts off the water supply. As the water level drops, the float descends and reopens the valve, maintaining consistent water levels without manual intervention.
