Why Is My Drain Making a Gurgling Sound?

If you’ve noticed your drain making a strange gurgling sound, it’s more than just an annoyance—it’s your plumbing system telling you something isn’t right. Gurgling often points to air pockets caused by partial clogs or blocked vent pipes. At 2 Sons Plumbing Bellevue, we help homeowners solve these problems quickly before they turn into costly repairs.

Drain Gurgling? Here’s Why It Happens

That odd gurgling sound coming from your drain might seem harmless at first, but it’s actually your plumbing sending out a warning. What’s happening is simple: air is getting trapped in the pipes, and instead of water flowing smoothly, it’s bubbling its way past those air pockets—creating the noise you’re hearing.

A few common culprits are behind it:

Partial clogs – Everyday things like grease, soap, or food scraps slowly building up inside the pipe.
Blocked vent pipes – Leaves, dirt, or even the occasional bird nest blocking the roof vent that’s supposed to let air out.
Sewer line problems – A deeper blockage in the main line, which often needs a professional to clear.

At first, it might just sound like an odd bubbling noise after you flush or drain the sink. But if you ignore it, that little warning can turn into something bigger—like slow drains or even a messy sewage backup.

DIY Steps Bellevue Homeowners Can Try

Before calling a plumber, there are a couple of safe things you can try at home:

Check your roof vent – Look for leaves, twigs, or other debris that may be blocking airflow.
Try an enzyme-based cleaner overnight – These natural cleaners can help break down buildup without damaging your pipes.
If the gurgling stops, the problem may have been minor. But if the noise continues—or if you notice multiple drains acting up—it’s time to bring in a professional.

Dave and David came and cleared out a huge clog in my kitchen sink (both sides) that has been plaguing us for a while as well a ton of glass shards that got into the drain when our glass fridge shelf broke. Dave walked us through each step of the process and explained everything which was excellent. He also gave us advice about galvanized piping replacement. They even gave us a few free parts for the sink drain that had eroded away and didn’t charge extra for it!! All around 5 star service!!!

Fantastic service and communication. Local company. Solved my clogged basement laundry utility sink. Dave and David were courteous, informative, professional and easy to engage with. Scheduling was easy (they came the next day) and they arrived within the expected time window. Transparent pricing and i could also apply a coupon. I will use them again.

Great service and Dave their plumber is the best. We have an odd house with even odder plumbing. The pipes are a mess of grandfathered-in open air nonsense, when our pump started making some noises (and a little leaking) after some DIY heat tape adventures (getting ready for colder weather), we were worried that we would need a massive repair but Dave came and looked at it and immediately realized we had unplugged the float plug from the pump plug which was 90% of the problem and the leak just need a little tightening of a flex joint. The company was quick and didn't charge for an estimate or in this case a quick "thats not plugged in right". The experience and the overall professionalism has convinced me that when I do finally need that big repair job, I'll call these guys.

Booking an appointment was extremely easy, and we were able to get one just the next day. Communication was excellent with timely reminders and a call before our appointment. Kerry did a fantastic job both advising us and effectively resolving our issue.

I have all good things to say about 2 Sons Plumbing. My first experience was a few years ago and the whole process went very smoothly. Making the appointment was easy and quick, the repair was done with no problem and I thought the price was fair. Recently, Dave from 2 Sons came out to look at several plumbing problems I was having and, within a matter of minutes, all of the problems were diagnosed. Dave gave me options and estimates all before he left my house. I haven’t had the work done yet but appreciate the information and the prices seemed fair to me. Dave was on time, professional and very knowledgeable. 2 Sons are my go to Plumbers.

Bob at 2 Sons Plumbing was amazing! We had a horribly backed up kitchen sink drain and he was able to fix it, and save us some money in the process! He heard what we had to say about our issue and double checked everything. Super friendly and very helpful. Thank you for the amazing work Bob!

Stellar job by Carey and his team at 2sons today. I had a complex job -- installing a yard hydrant/faucet for a garden across the (private) street. They had to go into the floor of the garage, run piping under the floor, out of the house, across the road. Had to cut into the asphalt, trench down a couple feet, then patch it all up again, including fixing the garage concrete floor. Super job. Looks really clean. Got it all done in a day.

A wonderful experience every time with 2 Sons plumbing. Jake and Angelo helped us with our plumbing issue. They showed up on time and gave a very reasonable estimate for the repair. We ended up replacing a couple of toilets and a part of a sink drain. They came back the next day to complete the work due to our schedule. Excellent communication, prompt, and hard working! Thank you so much Jake and Angelo!! We are very happy with 2 Sons and have used them multiple times.

Brandon and Ethan were awesome. I had a basic plumbing issue that I was too scared to address myself. They were very non judgmental and provided excellent customer service. I totally recommend 2 Sons Plumbing.
