"FOCET" MAKE Foot valves are beneficial because they prevent damage to water pumps that can occur due to dry runs, as well as stopping wastage of energy.
These valves are a necessary part of all water pumping systems. The example above explains how the foot valve works on a very small scale. Consider the implications of not using a foot valve in larger, higher-volume situations.
In situations where water is being pumped from sumps on the ground to water tanks on top of buildings, it’s necessary to use powerful electric pumps. Like the example, these pumps typically work by producing a suction that forces the water upward through the piping system to the desired tank.
While the pump is running, there’s a constant column of water in the pipe as a result of the suction that’s created. But when the pump is shut off, the suction disappears, and gravity affects the water column. If there wasn’t a foot valve in place, the water would flow downward through the pipe, back to its original source. The pipe would be left empty of water, instead filled with air.
Then, when the pump is turned back on, the air that is in the pipe will oppose the flow of water, and even though the pump is on, water will not move through the pipe. When this happens, it causes dry runs, which can damage the pump if it isn’t addressed quickly.
The foot valve solves this problem effectively. It doesn’t allow any backflow of water when the pump is turned off. The pump stays primed for the next time it’s used.
