Nds Hyp 250 Hydro-pop Riser 9 in Compression Inlet

Product Description

The NDS HYP 250 is a 9-inch Hydro-Pop riser designed for use in landscape irrigation and drainage systems. It accepts a 1/4-inch compression inlet, allowing for a secure, tool-assisted connection to supply tubing without the need for barbed fittings or adhesives. The riser is designed to bring irrigation emitters or spray heads to the correct grade in turf, groundcover, or planting bed applications. Licensed irrigation contractors and landscape professionals are the primary installers of this component.

The HYP 250 is suited for residential and light commercial landscape irrigation installations where a pop-up or fixed riser is needed to position a spray head or emitter at the correct height above grade. It is commonly used in drip and low-volume irrigation layouts where 1/4-inch distribution tubing feeds individual emitter stations off a main supply line.

Key Features

• 9-inch riser height positions spray heads or emitters at proper grade
• 1/4-inch compression inlet provides a secure, leak-resistant tubing connection
• Compatible with standard 1/4-inch irrigation distribution tubing
• Compression fitting design eliminates the need for barbed connectors or adhesives
• Lightweight construction at 0.13 pounds for easy handling and installation

Compatibility

Designed as an OEM-style replacement or new-installation riser for landscape drip and low-volume irrigation systems using 1/4-inch distribution tubing.

Installation Notes

Installation is typically performed by licensed irrigation contractors or landscape professionals. Shut off the irrigation system and relieve line pressure before making any tubing connections. The compression inlet should be hand-tightened and then snugged with pliers — do not overtighten, as this can crack the fitting body. Verify riser height against finish grade before backfilling around the assembly.
