Heavy and rock solid
This thing is a beast. Have a and very well constructed. Every bit of it is high quality. This works excellent for filtering lake water for irrigation. I'm using it inside a filter bag.

Keeping the Dirt Out
I’m using this for a foot valve & check valve on a TDRRICH Water Pressure Booster Pump for House,110V RV Water Transfer 5.5GPM 75PSI Self-priming Pump,Diaphragm Power Water Sprinkler & Irrigation Pump setup for my gardens. Works great for keeping the dirt out of the pump and water in the line in the suction or inlet side. This way my pump stays primed when I shut it off.
