Copper Floats Round 10 inch to 12 inch

Copper Floats Round are hollow copper balls that screw onto the arm of a float valve. As the water rises, the float lifts the arm and shuts the valve off, so the tank stops filling at the right level.

When to replace Copper Floats Round

A float that has split or been holed fills with water and sinks. Then the valve never closes and the tank overflows. If you shake an old float and hear water inside, it is time for a new one. Copper floats are also used where a plastic float would be too small, for example on big storage tanks and float valves with long arms.

Larger floats give more lift, which helps the valve close firmly against higher pressure. The 10″ and 12″ sizes suit large cold water storage tanks and commercial cisterns rather than a small WC cistern.

Check the thread on the arm before ordering. Float valves and spares are in Filling Valves.

Common Questions

How do I know my copper float has failed?

A float that has taken in water sits low or sinks, so the valve never shuts and the overflow runs. Shake it: if you hear water sloshing inside, replace it.

Will a 10″ or 12″ float fit a small WC cistern?

Usually not. These sizes are for big storage tanks and float valves with long arms, where a larger float gives more lift to close the valve.

Do I need to match the thread on the arm?

Yes. Check the thread on the float valve arm against the boss on the float, or bring the old float in so it can be compared.
