Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Where it shines

This Dewalt ABS check valve is ideal for small-diameter drainage and plumbing runs where backflow protection matters. Use it in residential basements, laundry areas, utility sinks, or any ABS piping segment where preventing reverse flow protects fixtures and equipment. The dual-size inlet and pipe compatibility simplify retrofits and new installs alike, letting you pair with existing 1-1/4" or 1-1/2" ABS lines without adapters.

Why choose this Dewalt valve

Designed for reliable one-way flow in a compact footprint, this check valve leverages ABS construction to stay lightweight and corrosion-resistant. Its boxed packaging keeps the valve protected from damage during shipping and storage, so you’re ready to install with confidence.

Practical tips

  • Confirm your line size is 1-1/4" or 1-1/2" before purchasing to ensure a proper seal.
  • Install where the valve can be easily inspected and accessed for future maintenance.
  • After installation, test the system for leaks and verify unidirectional flow by introducing a simple test signal through the line.
