The Noises the Toilet Makes After Flushing

toilet1Toilets nowadays are attached to a complex plumbing system which not just takes waste away from the home, but also brings it to sewage treatment plants. This connection is mostly the reason why toilets make an array of noises. However, toilet noises are also due to a part or two malfunctioning or breaking down.


The most common toilet noise is a moan, and the sound is almost as though the toilet is gasping for air. Usually, the sound can be heard during the night and is due to an increase of water pressure in municipal systems. Specifically, this is due to water pressure placing additional strain on a misaligned or worn ballcock. As this part ages, it becomes less flexible and vibrates when pressed, causing the moan. Getting a new fill valve and ballcock installed for you by a plumber will sort out the annoying sound for good.


Although gurgling is normal when the toilet is flushed and a few minutes after it, constant gurgling several minutes after flushing is a common indication of a blocked vent. Some suction is made in the pipework after you flush, and another pipe, one which vents from your house’s exterior, relieves the pressure of the suction. If the vent pipe is blocked, a build-up of suction occurs and air and water get pulled to the pipe system. This causes gurgling. Calling a plumbing company to help you out with unclogging the vent solves the problem.


Toilets that are functional, but produce whistling noises, will most likely have out-dated ballcock assemblies and refill valves. Older toilets fill slower than the new toilets, and, at times, the pressure can go all the way up until the ballcock opens enough to cause the toilet to whistle while it is filled with water. A plumber can replace worn-out parts of the toilet so the whistling is eliminated.


Like gurgling, trickling is a sound you should hear for a few seconds to one minute after flushing, but if it lasts longer than that, it is a sign of something wrong with the toilet. Usually, the problem is due to a tiny leak in the flapper which is due to the chain getting caught on another part or a crack on the ring that surrounds the valve seat or flapper. This issue can prove to be costly since if the leak is not sorted out, hundreds of gallons of water are wasted per hour due to the tank’s inability to hold water.

Keep in mind that, due to the sensitivity and small size of the toilet parts, only licensed, skilled, and properly equipped plumbers should sort out the toilet noises. Go beyond the usual sources when looking for names of plumbers; it’s advised that you ask those in the fields of construction and real estate as well.

Once a list of names is created, call them one by one. See how comfortable you are with the way they deal with your issue, how early they can fix your problem, and if their prices are reasonable.
