Why is My Plumbing Whistling?
Water Pressure too High
The water pressure is your most likely culprit when it comes to plumbing whistling. If the water pressure or velocity is too high, it will whistle when forced through the openings. You can fix this by reducing the water pressure or velocity. Your water pressure should not exceed 60 psi, but most home water main lines work best at around 50 psi. Test your water pressure to see if it is too high and take measures to reduce it, such as a pressure-reducing valve. If you already have a pressure-reducing valve, it may need to be adjusted or replaced if it has deteriorated.
Look at Your Fixtures
When forcing water through an opening that is too small, a plumbing whistling noise can occur. Plumbing components are designed to handle only so much pressure. If your fixtures are new but make a whistling noise, you may have to adjust your water pressure. On the other hand, if your fixtures are older, some parts might have degraded over time. If you have hard water, the mineral buildup could be the cause of the plumbing whistling. Check to see if there is visible buildup on your shower or sinks aerator. If there is a visible white crust, clean it with vinegar and a bristle brush. Cleaning will often clear the openings and stop the whistling. If there is no mineral buildup or cleaning it does not fix your problem, you should probably consider replacing it.
