How Do I Stop My Water Tank Overflowing? Float Valve or Float Switch
Quick answer

If the tank fills from mains or a gravity line, fit a float valve on the inlet: the float rises and shuts the water off by itself, with no electricity. If a pump fills the tank, use a float switch that stops the pump at the set level. Always keep a working overflow pipe as backup, because any float can stick or fail.

05Frequently asked questions

How much does a float switch cost in Kenya?

Generic switches are commonly listed from about KSh 300 to 1,500 and branded ones such as Dayliff around KSh 2,500, but check the current price and rating.

Can a float switch run my pump directly?

Only if its current rating is above the pump's. Larger pumps need a contactor.
