Plastic Foot Valves FAQs
What is a Foot Valve?
A foot valve is a type of check valve that only allows one-way flow. You can use foot valves when you have situations that need a pump, such as when water needs to be extracted from an underground well. Foot valves are ideal for use in pools, ponds, and wells. Their typical materials include PVC, plastic, bronze, cast iron, and stainless steel.

PVC Foot Valves Advantages
1.These foot valves prevent damage to water pumps that can occur due to dry runs, as well as stop wastage of energy.
2.Without these foot valves, the water would flow down through the pipe, back to its original source when the pump is shut off.
3.The internal balls ensure quick sealing and valve reaction as well as the flexibility to fit various types of water pump uses.
4.They are cheaper to use, as compared to other valves used to prime a pump.
5.Good quality foot valves help extend the overall lifespan of water pumps.
6.They are cost-effective and lightweight.
