Cause; Increase in water pressure

Water pipes make a humming noise when water pressure is too high in that the water pipes start vibrating, leading to a humming sound. The cause of high water pressure might be the water pressure regulator that is not regulating the pressure. In addition to that, the water pressure becomes high depending on the home and water source.

Solution; Reset the water pressure regulator

When the water pressure is too high in the water pipes, consider regulating the pressure using the water pressure regulator by resetting the pressure to normal. The water pressure regulator is a device you mount at the exact position of water passing to the house.

If there is no water pressure at home, you should install it to help reduce the humming sound at the water pipes. The steps below show how to reset the water pressure regulator;

  • Switch off the water pipes to reset the new pressure level.
  • Switch on the water pressure regulator.
  • Adjust the pressure level to your preference.
  • Turn on the water pipes to release water.
  • Check the water pressure in the water pipes.
  • If the pressure is normal, the water is good to go and if the pressure is still high, continue adjusting until you attain the normal force.

Cause; Availability of dirty particles in the water pipes

Dirty particles like leaves and debris do accumulate in water pipes blocking the way for water. Therefore when water passes through the lines, they gargle as they force themselves through the particles producing a humming sound in the water pipes.

Solution; clean the water pipes

When the water pipes accumulate dirt, consider cleaning the water pipes to avoid damaging their components. The steps bellows explain how to clean the water pipes;

  • Fix new screws and tighten them to avoid other noises.
  • Switch on the water pipes taking note of the humming noise.

Cause; Sudden closing of valves

Water pipes make a humming noise when you suddenly close the valves since water moving with high pressure is suddenly put to an end. Therefore, the moving water produces a humming sound when they meet the end at the valves.

Solution; avoid closing the valves suddenly

Cause; Presence of a leak within the water pipes

Water pipes make a humming noise when water is passing through, and some do exist where there are leaks in the water pipes. When water moves out through the leaks, there is a humming noise in the water pipes.

Solution; seal the leaks

When sealing the leaks, collect all the requirements needed, like the sealing tape that wraps the leaking area.

  • Switch off the flow of water.
  • Disconnect the water pipes
  • Turn on the water pipes to confirm if there are no leaks in the water pipes.

Cause; Faulty flapper

In the toilet section, water pipes tend to make a humming noise when flushing the toilet. When flashing a bathroom, you use flappers, and therefore if the flappers are faulty, the water in the tank moves out when not in use, making a humming sound.

Solution; replace the faulty flapper
