What causes a whistle?
Whistles can take a number of shapes and forms. Air enters the whistle at one end. As the air reaches the other, closed end, all the air molecules “pile up” on top of each other and cause a high-pressure region. The air escapes out the little hole in the end, making the noise you hear.

An easy way to eliminate whistling water pipes is to install a water pressure valve. Often, the water supply company can install this type of valve, which will reduce the water pressure and eliminate the whistling and hissing noises of behind your walls and ceiling.
Will my water tank explode?
While rare, residential water heater explosions do occur and can be deadly. Explosions are possible with both gas and electric tank water heaters, primarily those that are poorly maintained.

Over time, this drain valve may become loose allowing air to come in which causes the whistling sound.
Why does my water heater make a popping noise?
Popping noises in gas and electric water heaters are the result of mineral deposits that build up in the tank. As the water heats up, steam is produced at the deposits and makes popping noises when it releases.

What causes knocking sound in hot water heater?
A knocking sound from inside the baseboard heater is caused by the expansion of the pipes when hot water enters the pipe. When cold water enters the boiler to be heated and hot water flows into the baseboard and then back into the boiler, the pipe expands and creates noise.
