In rare cases, a failed expansion tank, quick closing pressure relief valves on new appliances, bad vacuum breakers, faulty valves with loose washers, or even improperly strapped pipes can be the cause of those noises coming from your pressure relief valve.
One of the most common issues is related to water pressure. When the water pressure into your home is too high, it can cause the humming sound. … Turn off each valve while the humming sound is present, and if the sound stops, you have found the source. It may be necessary to replace the valve for the fill tank.

Water expands as it heats up. … When you call for water by opening a faucet, the extra pressure introduced by the water heater then causes the pressure-reducing valve to vibrate as it compensates for this extra pressure. Some pressure-reducing valves have a builtin bypass to provide an escape for this back pressure.
A foghorn sound in your plumbing could be a number of things.

Symptoms of Regulator Failure If you have a regulator and it fails, you’ll notice an immediate reaction in your home. For instance, you’ll experience irregular water pressure that is hard to control with your sink, toilet, or bathtub faucets. The pressure is likely too high or too low.
If your water pressure is set too high as it moves into your home, it can cause your pipes to vibrate. This vibration often makes a humming sound in your pipes. Home water pressure should typically be between 40 and 60 psi and anything more than that is a signal your water pressure is too high.
Water pipes that make a groaning or hissing noise are often indicating a constriction somewhere in the waterline. As the water flows through the narrower section, it will create this noise. … If it continues to fill with water past the desired shutoff and runs down the overflow, this, too, could create a hissing sound.
Usually, banging noises in the pipes come from a problem with water pressure or water flow. Two of the most common causes are water hammers and trapped air bubbles. … Water hammers can also result in a series of smaller bangs in your pipes. Air can become trapped in your pipes due to issues in the water line.

Most pressure reducing valves have an arrow indicating the proper direction of water flow through the valve. A valve installed backwards is an installation issue. If the valve is installed backwards, the boiler will not get any makeup water.
Ultimately, such pressure can damage water-using appliances and may even lead to leaks and the problem known as water hammer. Fortunately, you can keep your water pressure within a safe range by installing a pressure regulator valve on your main water line.

Excessive flexing of the metal diaphragm can cause a radial crack, which allows gas to escape to the atmosphere through the vent hole in the bonnet. The second and perhaps the most common type of regulator failure is the internal leak, sometimes called creep or crawl.
A wall outlet will buzz if there is a loose connection or faulty wiring. A loose connection typically occurs when the plugs that hold the wiring for the outlet come loose over time. If you live in an older house and think that you have a loose connection, you will need to have the outlet replaced.

Pressure Regulator Valve is fitted in a Parallel circuit between Pump and the tank controlling the maximum working pressure in System. Pressure Reducing Valve maintains a constant lower working pressure in an auxiliary branch circuit, which is a small part of the main circuit set to work at a greater working pressure.
1. A Water Regulator Valve May Be Needed to Save Water. If the water pressure level coming into your home from the city exceeds 80 psi, you need a water pressure regulator. Reducing the system pressure 10 to 20 psi can save thousands of gallons a year in the typical home.
