What causes a float valve not to work correctly

[kac0143]

I have had several float valves not work correctly causing water on the floor. What causes them to fail? Thanks

What type of float valves are we talking? Like ATO float valves, Freshwater reservoir valves? where in the system are they?

They are in the water barrels for water change

Can you share pictures with us so we can see how they're setup?
