Recently, I started hearing a constant humming noise in the pipes. Especially at night—there is a low sound, as if someone turned on an engine under the floor. There are no visible leaks, and the water is working normally. Could this be due to pressure or air pockets? If anyone has had a similar experience, please advise on how to find the cause. Maybe someone knows a plumber who has diagnostic equipment?
I also noticed that the sound gets louder when my neighbors turn on their water. Perhaps the problem is somewhere in the riser or in the pressure control valves. It would be helpful to know if this can really be fixed without replacing the pipes, and who to call to have the system checked professionally and without unnecessary expense.
Yes, humming in pipes is a fairly common but unpleasant problem. If the water is working normally and there are no visible leaks, then most often it is air pockets, pressure fluctuations, or faulty pressure control valves. The sounds intensify when neighbors use water, which confirms that the problem may be in the riser or the building's common water supply. To determine the exact cause, professional diagnostics are required, including pressure measurement and valve testing, possibly even using special devices to detect air pockets or pipe vibrations. It is not necessary to replace the pipes immediately — often it is enough to adjust the system correctly or replace the valve.
