Can you hear a gurgling noise coming from the sink drain? Or is your toilet making weird sounds?
Regardless of the gurgling sound, not one area should gurgle from your plumbing system.
Here we will find out the common causes why your sink drain makes weird noises.
In some cases, the gurgling noise happens when you drain the sink of water. If that’s the case, there’s a good chance that the problem is directly associated with the drain’s vents.
See, the vent on your sink is used to prevent a vacuum from happening when you fill the sink with water. If the drain isn’t properly venting, air will fill the vacuum created by the water and cause the gurgling sound.
If you hear this noise often, it could be that the vents of that sink weren’t properly installed.
To have this fixed, the vent will have to be repaired and a professional plumber will have to correctly install the vent pipes.
Like the sink, your home’s plumbing system has vent pipes that let sewer gases out allowing them to safely escape your home.
If the vent system is blocked the sewage gases will not be able to find their way out, causing them to come back up through the drain. While this could look like something from a horror movie, it’s just gas trying to make its way out of the pipes.
Nevertheless, it should be approached with caution as these gases — especially in large concentrations — can be flammable and sometimes be explosive.
That said, if you hear gurgling sounds in your sink coupled with a foul odour, it’s strongly recommended that you contact an experienced plumber to fix the issue.
Just below the sink is the P-trap. Typically exposed on bathroom sinks while hidden under the cabinet for kitchen sinks, a P-trap is designed to prevent debris from entering the plumbing system.
Over time, the P-trap can accumulate debris from food waste as well as oil from the plates. This clogs the P-trap and can cause a gurgling sound.
Your P-trap also functions to protect your home from nasty smells by creating a water seal that prevents gas from coming out of your drains.
Spotting a P-trap requires you to look for a piece of curved pipe under the sink. That curved structure is what holds the water and creates the seal.
To ensure that your P-trap is working properly, avoid throwing food waste in the sink. If it’s clogged, you might need to disassemble the P-trap. It should be replaced if it’s broken.
Repairing the P-trap is something you can do on your own, but if you have no idea how to go about this fix, you can always contact an expert.
Sometimes, the gurgling sounds are just caused by a blocked drain. Just like the blocked P-trap, a blocked drain will obstruct the flow of water leading to the noises you hear when using the sink.
The thing with blocked and clogged drains is that the gurgling sound is usually just the start of the problem. On that note, it’s important to remove the obstruction right away.
You can purchase drain cleaners and clog removers but it’s important that you make sure that the construction won’t return. In most cases, the blockages are caused by small pieces of food, fat, oil, and grease which may melt but can accumulate again over time.
To ensure that the drain is completely clean and that the obstruction is removed entirely, it’s best to contact an expert plumber who will use advanced plumbing tools like a jet spray.
