USA Made Pop-Up Drainage Emitter for 4 Drain Fittings, Green Plastic

Pop-Up Relief Valve with 4″ Elbow

Manufactured in the USA, this pop-up water relief valve, also known as a pop-up drainage emitter, remains closed under normal conditions but opens when hydrostatic pressure builds up. The valve is designed to release excess water as drainage pipes fill and pressure increases. Once the water is discharged, a stainless steel spring automatically retracts the cover to its closed and flush position. The sleek design of the product allows it to seamlessly blend into its surroundings.

Constructed from structurally foamed High Density Polyethylene (HDPE) with a UV inhibitor, this relief valve is resistant to sun damage. It is commonly used at the discharge end of drainage pipes and can be installed vertically or horizontally.
