Product Description
Pop-Up Relief Valve with Adapter

This item, commonly known as a Pop-Up Drainage Emitter, is normally closed except when there is a build-up of hydrostatic pressure.  When the drainage pipes fill and build up slight pressure, the cover rises to allow the excess water to escape. Once the water is discharged, the pressure drops, a stainless steel spring automatically retracts and the cover is closed to a flush position. 

The flush design of the product ensures that it blends well into the surrounding area. The Pop-Up body is manufactured from structurally foamed High Density Polyethylene (HDPE) with a UV inhibitor to reduce sun damage, while the Elbow (which comes with a pre-drilled hole to drain excess water) is manufactured from PVC and the Adapter from High Impact Polystyrene (HIPS). 
  • UV stabilized to protect from sun degradation.
  • Cover rises 1/2" to discharge excess water in system.
  • Spring automatically retracts cover to flush position after excess water is discharged.
  • Can be used in both vertical and horizontal position.
  • Weight: 1.4 lbs.
  • Made in the USA.

Typical application for this product is at the discharge end of the drainage pipe. Connects to 3" & 4" Sewer & Drain Pipe, 3" & 4" Corrugated Pipe and 3" & 4" Triple Wall Pipe.
