The loud noise you hear is not water dripping. It is air being sucked through the P-trap by water flowing through a choke point somewhere between the trap and the next downstream vented pipe. The effect of a blocked drain vent goes beyond the nerve wracking noise.

Why does my drain sound like its dripping?

If your drain makes a dripping sound or a sound like running water inside the pipes, the problem is a leak from one or more appliances or fixtures. When the appliance leaks, the water is dripping down into the drain line causing this sound. Repairing the fixture itself is the only way to stop the leak.

Does a garbage disposal need a separate P-trap?

The plumbing code has a lot of regulations, but none is as important as this one: Every drain must have a P-trap. Shower and tub drains have to have them, toilets have built-in traps and sink drains must have them, even those with garbage disposals.

Why does water come out of my sink when I run the garbage disposal?

The material trapped in the drain builds up until the pipe is fully blocked, causing the water to back up through the drain pipe that the sink and the disposal share. The good news is that unblocking a garbage disposal drain is a task you can do yourself, without an expensive call to a plumber.

Is it normal to hear water running through pipes?

In fact, it is not uncommon to hear flowing water as it travels through the plumbing system. This is especially true with older homes when it was common to leave drain pipes exposed, such as the ceiling of a basement or garage.

What does it mean when you hear water running in my walls?

Another reason why you might hear dripping behind the walls is when your pipes are becoming clogged. Clear drains usually allow quick passage of water, which results in the dripping stopping sooner. However, with partially blocked pipes, the water will run down slowly, which means you’ll hear dripping for longer.
