What can I do for water pipes that make a “chunk, chunk” sound when the water is running?

Question by Ysmudge: What can I do for water pipes that make a "chunk, chunk" sound when the water is running?

I have city supplied water, no pump or well.

My water pipes make a "chunk, chunk, chunk" sound in the house when the water is running (shower, dish washer, sink, etc.). I saw a question & answer here about pipe rumbling noise *after* the water is turned off being related to air in the pipes, but my problem is while the water is running - it stops when you turn off the water. Is this a similar problem (air)?

What can I do to make it stop doing that?




Best answer:

Answer by -R
The banging sound must be coming from air, the air might be mixing into the water line while it's running. (are you on a well system?) The key is to make sure you have risers at every faucet in the home (pipe that goes up, and stops about 14" up)
Another thing is to check the basement for any pipe that is not secured (swaying pipe)

And finally if none of this is your problem, you may just need to install a water hammer arrestor.
