The Ultimate Buying Guide for Washing Machine Water Hammer Arrestors
Do you hear loud banging noises when your washing machine finishes its fill cycle? That noise is called water hammer. It happens when fast-moving water suddenly stops. A water hammer arrestor solves this problem. It saves your pipes from damage. This guide helps you choose the best one for your home.
Key Features to Look For
When shopping for an arrestor, look closely at these features:
- Connection Size: Make sure the fitting matches your washing machine’s hose connection. Common sizes are 3/4 inch.
- Material Quality: Strong materials last longer. Look for brass or high-quality plastic bodies.
- Air Chamber Design: A good design quickly absorbs the shockwave. Some models use a piston or diaphragm.
- Ease of Installation: Simple screw-on designs make setup fast.
Important Materials Matter
The material of the arrestor affects how long it works. Good materials resist corrosion from water.
Body Materials:
- Brass: This is the best choice. Brass does not rust. It handles high water pressure well.
- Durable Plastic (e.g., ABS): Cheaper options use strong plastic. These work fine but might not last as long as brass, especially in areas with very hot water.
Internal Components:
Inside, the part that stops the shock is crucial. Many good arrestors use a sealed air cushion. This cushion compresses when the water slams shut. Ensure the manufacturer clearly states the internal components are durable.
Factors That Improve or Reduce Quality
Not all arrestors perform the same. A few factors really change the quality of the product you buy.
Factors That Improve Quality:
- Tested Performance: Arrestors tested to standards (like ASSE 1010) offer reliable results.
- Pre-Charged Air Chamber: Arrestors that come pre-charged are ready to work immediately after installation.
- Compact Size: Smaller arrestors fit better in tight spaces behind the washer.
Factors That Reduce Quality:
- No Seals or Poor Seals: If the air chamber leaks over time, the arrestor stops working. This often happens with lower-quality plastic models.
- Thin Walls: Thin bodies can crack under extreme water pressure spikes.
User Experience and Use Cases
Using a water hammer arrestor should be simple. Most users report immediate relief from banging pipes. The main use case is behind a washing machine because it uses fast-closing valves.
Installation Experience:
Most people find installation easy. You usually screw the arrestor onto the washing machine’s hot or cold water outlet valve *before* attaching the hose. If you have two hoses, you might need two arrestors.
When Do You Need One?
You definitely need an arrestor if you hear banging when:
- The washing machine fills quickly.
- The dishwasher runs its fill cycle.
- A nearby faucet shuts off suddenly.
If your pipes are older or hidden in walls, installing an arrestor protects them from unnecessary stress.
10 Frequently Asked Questions (FAQ)
Q: What exactly is water hammer?
A: Water hammer is a shockwave or vibration in your plumbing system. It happens when water flowing fast stops suddenly, usually when a solenoid valve (like in your washer) snaps shut.
Q: Do I need an arrestor for both hot and cold water lines?
A: Yes, if both lines cause banging when the machine fills. Often, the hot water line is the main culprit.
Q: How do I know if my arrestor is working?
A: If the loud banging noise disappears after you install the device, it is working correctly.
Q: Can I install this myself?
A: Absolutely. Most washing machine arrestors screw directly onto the existing hose bibs. It is a simple DIY job.
Q: Will this affect my water pressure?
A: A properly functioning arrestor should not lower your normal water pressure. It only acts when the flow suddenly stops.
Q: How long do these devices typically last?
A: High-quality brass arrestors can last ten years or more. Plastic ones might last five to seven years before the internal seal degrades.
Q: What if the banging continues after installation?
A: If the noise continues, the problem might be elsewhere, or you might need a second arrestor on the other water line (hot or cold).
Q: Should I buy a piston or diaphragm type?
A: Both are effective. Piston types are common and reliable. Diaphragm types sometimes offer a slightly better seal against water leakage into the air chamber.
Q: Where is the best place to install it?
A: Install the arrestor as close to the washing machine valve as possible for the best shock absorption.
Q: Can I use a washing machine arrestor for my ice maker?
A: Yes, if the ice maker uses a standard 3/4 inch connection, the same arrestor can protect those pipes too.
