FAQs

What is water hammer?

Water hammer is the banging noise that occurs in pipes when water flow is abruptly stopped or changed, creating a pressure surge.

Where should I install the water hammer arrestor?

Install the arrestor as close as possible (within 1.5 meters) to the appliance or fixture causing the water hammer.

Can I install it vertically?

Yes, the Midbrass Water Hammer Arrestor can be installed vertically or horizontally.

Do I need a pressure-reducing valve?

If your water system pressure exceeds 60psi (4 Bar), a pressure-reducing valve is recommended before the arrestor.

What fittings do I need?

The arrestor uses standard 3/4"M-3/4"F compression fittings for washing machine valves.

What if the water hammer is very loud?

For severe water hammer, consider installing multiple arrestors in-line for increased protection.

Will this fix all plumbing noises?

No, this arrestor is specifically designed to address water hammer. Other plumbing noises may have different causes.

How long will the arrestor last?

The Midbrass Water Hammer Arrestor is built for long-term use, providing lasting protection against water hammer.

Troubleshooting

Banging persists after installation.

Ensure the arrestor is installed within 1.5m of the source. If the issue is severe, install additional arrestors. Also, check for a pressure-reducing valve if your system exceeds 60psi.

Leaks at the connections.

Tighten connections, but avoid overtightening. Ensure fittings are properly seated and consider using Teflon tape if needed.

Water pressure seems low after installation.

Check for any blockage in the arrestor or fittings. Ensure the water supply valves are fully open. If the issue continues, contact a plumber.
