Keep an Ear Out for These Plumbing Noises

It’s common to hear noises from your plumbing system, such as a running toilet for a few seconds after you flush. However, some plumbing noises can signal an issue with your system. 

South West Plumbing will be sharing a few noises you should be aware of and what they could mean for your plumbing system. 


Banging noises usually occur when there is a water hammer in your pipes. This is a result of high water pressure or a pressure surge. Unfortunately, water hammers can cause issues like leaks or ruptured pipes. If you hear a banging sound when your dishwasher stops filling or when you turn off the faucet, it’s important to contact South West Plumbing.


A whistling faucet or showerhead usually indicates a clog somewhere in your system. Try cleaning both fixtures, and if the whistling still occurs, don’t hesitate to get in touch with our professional team.

Running Water

If you hear water running when your fixtures are turned off, it’s most likely an issue with your toilet. A constantly running toilet usually means you may need a new flush valve. 


Gurgling drains typically mean you have a blockage or air in your pipes. In this case, contact South West Plumbing for a drain cleaning. Our experienced drain technicians can perform a drain camera inspection to first inspect your drain & sewer system for blockages or other faults. Afterward, we can use hydro-jetting or rooting to clear your drain so you can get back to your daily routine.


Knocking sounds usually come from your water heater. When sediment builds up in the bottom of your water heater, it can reduce your water heater’s efficiency, creating a knocking noise.
