What Is a Water Hammer Arrestor

A water hammer arrestor is a mechanical device that is installed in a plumbing system to protect against the damaging effects of water hammer. Water hammer is a condition that can occur when there is a sudden change in the flow of water, such as when a valve is closed quickly. This can cause a shock wave to travel through the piping, which can damage fixtures, pipes, and other components in the system.

Water hammer arrestors are designed to cushion the shock of these sudden changes in water pressure, and they are particularly important in systems that use high-pressure pumps or where there are long runs of pipe. They are typically installed near valves, at junctions in the piping, or at the end of a run of pipe.

Where to install water hammer arrestor

The best place to install a water hammer arrestor is near a valve, at a junction in the piping, or at the end of a run of pipe. This will help to cushion the shock of sudden changes in water pressure and protect your plumbing system from damage.

How to Install a Water Hammer Arrestor

1. Locate the point where the water hammer arrestor will be installed. This is typically near a valve, at a junction in the piping, or at the end of a run of pipe.

2. Cut into the piping at the chosen location, using a pipe cutter.

3. Remove any burrs from the cut end of the pipe, using a deburring tool.

4. Install a tee fitting at the cut location, using PVC cement.

5. Slide the water hammer arrestor onto the tee fitting and tighten it in place with the included clamp.

6. Install a check valve into the other side of the tee, using PVC cement.

7. Check that all connections are tight and secure, and then run water through your plumbing system to test the new arrestor.

8. If you notice any leaks or other issues, consult a plumber for assistance in making repairs as necessary.

Types of Water Hammer Arrestors

There are several different types of water hammer arrestors available, including pneumatic shock absorbers, air chambers, and hydraulic cushions. Some water hammer arrestors may also include other features, such as check valves or pressure gauges. When choosing a water hammer arrestor for your plumbing system, it is important to consider factors like size requirements, water pressure, and the type of piping used in your system.

You should also consult a plumber or other professional to ensure that you choose the best arrestor for your needs.

Benefits of Installing a Water Hammer Arrestor

Installing a water hammer arrestor in your plumbing system can provide several benefits, including:

– Reducing the risk of damage to pipes, fixtures, and other components

– Preventing leaks and costly repairs

– Improving the overall performance of your plumbing system

– Protecting against health hazards that can occur when waterborne contaminants are present in the system
