Banging Pipes

Author: vidcity (FL)

I have a rental house in Colorado that was built in 2000. I got the following from my renter today:

When I ran the washing machine yesterday (and this has never happened before) the pipes inside the wall made a very loud pounding noise. I switched the setting from warm to cold and it stopped. I tried setting it back to warm and it started up again. Then I tried hot and it quieted down.

This morning when I ran the shower in my bathroom, the pipes made a loud hammering sound.
I noticed when the kitchen faucet runs there is no noise, so I turned on the shower in the hall. Again no noise. Whatever is happening is only happening in certain places and not systemic.

In the basement the sound is extremely loud, but the integrity of the exposed water pipes appears to be intact.

Is there something wrong that needs to be fixed? This has never happened before.

Author: packy (MA) one possibility is a pressure reducing valve gone bad giving you too much pressure ?? of course if you do not have a pressure reducing valve, disregard this reply. turn on a couple of faucets and try the offending fixtures at the same time.

Author: hj (AZ) I suspect a ressure reducing valve that is gong bad. When your valves aine using both hot and cold water at the sme time the flow is maximum and that is when a bad PRV woudl have problems.
