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.

About Product Overview

Sioux Chief MiniRester 5/8 in. Sweat In, Closed In Copper Water Hammer Arrester is a compact, copper solution designed to quiet plumbing shocks and protect your copper lines from pressure surges. Built for tight spaces and long-lasting performance, this little device helps reduce the banging sounds that happen when valves shut off suddenly, preserving fittings and extending the life of your fixtures.

Key reasons homeowners and professional installers reach for the MiniRester line include its precise fit for copper piping and its lead-free copper construction. The 5/8 in. Sweat inlet paired with a closed end provides a straightforward, durable installation in a typical copper supply run, making it ideal for under-sink valves, dishwashers, small laundry setups, and other nearby fixtures.

  • 5/8" sweat inlet: ready for soldered copper connections, with a secure, dependable seal.
  • Closed end: simple, rugged end design that suits compact, sectioned runs in tight spaces.
  • Lead-free copper construction: safe for potable water and compliant with modern plumbing standards.
  • NSF listed: trusted material and performance verification for residential installations.
  • Carded packaging: convenient retail display for quick selection on job sites or in stores.
  • Copper pipe compatibility: specifically tailored for copper systems, ensuring reliable integration with existing lines.
  • Compact MiniRester design: engineered to fit where larger arresters won’t, making it a smart choice for retrofit projects.

Who should consider this product? Homeowners updating kitchens or baths, DIY enthusiasts tackling under-sink reroutes, and professional plumbers who value a compact arrester that performs reliably without crowding nearby components. If you’ve noticed water hammer after shutting off a valve or feel vibration in copper lines, this arrester offers a practical, space-conscious remedy.

Practical usage ideas:

  • Place the MiniRester close to the fixture or appliance where shut-off impact is most noticeable to maximize shock absorption.
  • Use with standard copper piping and ensure proper sweat connection with clean, deburred copper to prevent leaks.
  • Test for leaks after installation and monitor the area for any changes in pipe movement or noise over time.
