Water Hammer Arrestor for Washing Machine - Compact 3/4 in Angle (Pack

In this review the CONSKIT Water Hammer Arrestor pack is evaluated for homeowners and DIY plumbers who want a compact, reliable fix for banging pipes and pressure shocks. The bottom line: this set of four compact angle arrestors is designed to be installed close to the source and offers a simple, durable way to reduce hydraulic shock and noise in washing machine and garden hose connections. It stands out for its lead-free brass body with stainless steel components and a space-saving swivel design that fits tighter installation locations.

Key Features

• Pack contents: Four angle water hammer arrestors provide multiple installs around a home or a complete replacement for dual-outlet washing machine boxes.
• Robust materials: Lead-free brass body and stainless steel construction deliver strong resistance to corrosion and wear for longer service life.
• Thread fit: 3/4 in female swivel hose thread to 3/4 in male hose thread offers compatibility with common washing machine and garden hose fittings.
• Space-optimized design: Compact angle shape and multidirectional installation allow placement in tighter spaces and easier alignment during fitment.
• Operating limits: Rated to handle up to 250 PSI and 180F, suitable for most residential water supply conditions.
• Certification: Meets cUPC and NSF-related requirements, supporting safe use on potable water supply lines.

Who It's For

Homeowners who hear knocking or banging near washers, toilets, faucets, or hose bibs and want a direct, hardware-based solution will appreciate this arrestor set. Its compact, angled shape and swivel thread make it useful where vertical or horizontal clearance is limited and where installers prefer a quick screw-in fix.

It is less suited for systems needing custom-sized arrestors or for large commercial plumbing where higher-rated industrial dampers are required. If a plumber requires an integrated box-style solution for a new rough-in, they may choose a different model intended for in-wall or recessed installations.

Pros & Cons

Pros

• Easy to install with swivel FHT that screws into place and aligns without forcing pipe orientation.
• Solid build quality from lead-free brass and stainless steel that customers report as durable and quieting.
• Effective noise reduction when placed close to the impact point, with reports of substantial elimination of hydraulic shock noise.
• Good value for a pack of four, allowing multiple installs or spares for future use.

Cons

• Performance depends on installing as close as possible to the source, so placement restrictions can limit effectiveness.
• Thread sizes are fixed at 3/4 in FHT x 3/4 in MHT, so adapters may be needed for nonstandard fittings.
