[High-quality materials] This product is made of high-quality brass, which is not easy to rust and is durable.
[Filter debris] The bottom valve is generally used for self-priming pumps (water pumps) to filter debris to prevent entering the pump.
[Reduce resistance] The use of a bottom valve can prevent the pump and the drive motor from rotating in the opposite direction, reduce the pump suction resistance, save energy and reduce consumption.
[Easy to install] The brass bottom valve only needs to be threaded to the suction hose, no complicated steps are required.
[Design] Allows pump to stay primed, letting liquid to flow in and keeping it from flowing back out.
