Have you ever been puzzled by your sink making gurgling noises, even though it seems to be draining just fine? This gurgling sound can be a bit disconcerting, but did you know that it's actually just air escaping from the drain? And while it's not an immediate red flag, hearing constantly gurgling coming from your plumbing does ultimately indicate that something's not quite right in your water system. So, what should your next steps be? Let’s take a look.
There are several reasons why your sink might be gurgling:
Your plumbing system includes vent pipes that help regulate air pressure, and if these become blocked, air can get trapped and escape through your sink, causing that gurgling sound.
Even if your sink drains well, partial blockages can disrupt normal water flow, leading to air bubbles and gurgles.
The P-trap - also known simply as a ‘trap’ in plumbing - is the curved pipe under your sink, and if it's improperly installed or has lost water seal due to evaporation or leakage, it can cause gurgling sounds.
If you notice gurgling when your washing machine drains, this could be due to improper installation or a shared drain system issue. This is a common scenario when the drain system starts to get overwhelmed by the water from the washer, which in turn causes air to be pushed back through the sink drain.
Gurgling sinks can sometimes be a precursor to more significant issues, like slow drainage or even backups, but you’ll also want to pay attention to how your sink and related appliances behave. If you notice slow drainage, water backing up, or persistent foul odours along with gurgling, it's time to take a closer look at your plumbing system.

As always, prevention is always the most cost-effective and simple way to keep your water system running correctly. To keep your sink functioning smoothly and avoid gurgling sounds, here are some of our expert tips:
Routine checks and cleaning of your sink and associated plumbing can prevent many issues; this includes clearing out debris and ensuring that the vent pipes remain unobstructed.
Make sure your plumbing fixtures, especially washing machines, are correctly installed, preferably by a professional. Incorrect installation can lead to a shared drain system getting overwhelmed, causing the gurgling sounds in your sink - an expert installation might be an upfront investment, but it can save you on repairs in the long run.
Always be cautious about what goes down your sink; avoid disposing of oils, large food particles, and non-biodegradable materials that can cause blockages over time. For oil, pour it into a bag or container, seal it, and throw it out.
There are also a number of safety measures to take into consideration when addressing sink gurgles and plumbing issues. Take note of the following:
If you're using chemical drain cleaners, follow the instructions carefully and ensure proper ventilation. These chemicals can be harsh and potentially damaging to your plumbing if misused, so use sparingly.
If you decide to use tools like a plumber's snake or auger, familiarise yourself with their safe and effective use to avoid injury or damaging your pipes - this is especially true if your plumbing is old.
Always be cautious when working around areas where water and electricity intersect, such as in the vicinity of a washing machine or dishwasher.
Sometimes, DIY solutions might not suffice, especially if the gurgling persists or is accompanied by other plumbing issues. If any of the following cases apply to you, it might be wise to consult a professional:
If the gurgling sound comes back frequently despite your efforts, it might indicate a deeper issue in the plumbing system.
When more than one drain in your home is gurgling or showing signs of blockage, it could point to a problem in the main sewer line.
