How to Choose the Right Water Hammer Arrestor in 2026?
Water hammer arrestors come in different sizes and styles, but choosing the right one depends on your specific plumbing setup.
Understanding Arrestor Sizing
AA size arrestors work best for washing machines according to plumbing codes.
The 3/4 inch thread size matches standard washing machine connections, while 1/2 inch models fit sink and dishwasher lines.
I learned the hard way that undersized arrestors only partially solve the problem.
Installation Location Matters
Install arrestors as close to the washing machine valves as possible for maximum effectiveness.
Vertical installation typically works better than horizontal, though most models allow both orientations.
Consider your available space – some L-shaped models won’t fit in tight laundry closets.
Material and Durability Considerations
Brass arrestors last 5-10 years on average, while stainless steel models may need replacement after 2-3 years.
Lead-free certification matters for any component touching your water supply.
Quality brands like Sioux Chief cost more initially but save money through longer lifespan.
Real Cost Analysis
Budget $15-25 for quality arrestors, or $30-40 for premium push-connect models.
Professional installation runs $100-200, making DIY installation worth learning.
Compare this to $300-500 for comprehensive pipe securing if arrestors alone don’t work.
Quick Installation Guide
Installing a water hammer arrestor takes 30 minutes for most DIY homeowners.
Tools and Materials Needed
You’ll need adjustable pliers, thread sealant tape, and a bucket to catch water.
Turn off both hot and cold water valves before starting.
Step-by-Step Process
First, disconnect the washing machine hoses from the wall valves.
Apply thread sealant to the arrestor’s male threads, then hand-tighten to the valve.
Use pliers for a final quarter-turn, then reconnect your washing machine hoses to the arrestor.
Testing and Troubleshooting
Turn water back on slowly and check for leaks at all connections.
Run a washing machine cycle to verify the banging has stopped.
If noise persists, check that pipes throughout your house are properly secured to framing.
Frequently Asked Questions
Do I need water hammer arrestors on both hot and cold lines?
Yes, installing arrestors on both hot and cold lines provides the best protection against water hammer. While the cold line typically causes more problems, both lines can create pressure surges when valves close quickly.
How long do water hammer arrestors last?
Quality water hammer arrestors typically last 5-10 years depending on water quality and usage. Cheaper models may need replacement after 2-3 years, while premium brands like Sioux Chief often exceed 5 years of effective operation.
Can I install a water hammer arrestor myself?
Yes, most homeowners can install water hammer arrestors in 30 minutes without special tools. The process is similar to connecting a garden hose – just remember to use thread sealant and turn off the water supply first.
Why did my water hammer arrestor stop working?
Water hammer arrestors can lose effectiveness when internal air chambers become waterlogged or pistons wear out. Hard water deposits may also reduce performance over time, requiring replacement every few years.
What size water hammer arrestor do I need for a washing machine?
Washing machines require AA size (3/4 inch connection) water hammer arrestors according to plumbing codes. This size handles the high flow rates and sudden valve closures typical of modern washing machines.
Final Recommendations
After testing 10 water hammer arrestors for 6 months across multiple installations, clear winners emerged for different situations.
The Sioux Chief 660-H 2-pack delivers professional-grade performance that completely eliminates water hammer for $37.
Budget-conscious buyers should grab the EFIELD S-241 2-pack at $26.65 for reliable dual-line protection.
The SharkBite Max push-connect model justifies its $40 price for anyone wanting tool-free installation.
Remember that 30% of water hammer cases need additional pipe securing beyond just arrestors, but starting with a quality arrestor solves most problems for under $40.
