FAQ
Frequently Asked Questions
Yes, in many contexts, particularly in toilet cisterns, a 'ballcock' is a type of float valve where the float is a ball. 'Float valve' is the more general technical term.
Absolutely. Float valves are used for oil, fuel, chemicals, and other liquids. The float material must be compatible with the liquid to avoid corrosion or chemical reaction.
Common signs include constant running or hissing sound from a toilet tank, inability to shut off water flow, slow filling, visible leakage from the valve, or an irregular water level in the tank.
Float valves are preferred for their simplicity, reliability, lower cost, and independence from electrical power. They are ideal for basic level control in non-critical applications where digital precision isn't required.
