Flow Gate with Elbow & Corrugated Pipe Adapter (Drainage Pop-Up)

If you already have corrugated pipe installed, and it’s not attached to anything to come up out of the ground, the flow gate can be purchased along with an elbow, and the Polylok 4" corrugated pipe adapter, to solve that problem. When water enters a drain pipe, it needs to go somewhere. The flow gate pops up when the pressure of the flowing water hits it, allowing the water to discharge. Once the water stops flowing, the flow gate closes again blocking anything from falling in. Forget worrying about finding debris, rodents, or anything else you don’t want in your pipes. Fade resistant, stainless steel spring, available in green.

Includes:

• Polylok Flow Gate
