A clogged drain is one of those problems that seems minor — until it isn't. One slow-draining sink is easy to ignore. But when the water starts backing up, the smell kicks in, or multiple drains are acting up at once, it's time to take it seriously.
Here's what you can try on your own, what you should skip, and when it's time to pick up the phone.
Start With the Simple Stuff
Before calling anyone, there are a few things worth trying — especially if it's a single, slow drain.
Plunger
A basic cup plunger can dislodge minor clogs in sinks and tubs. Make sure there's enough water in the basin to cover the plunger cup, create a good seal, and give it 10–15 firm pumps. This works best on soft clogs close to the drain opening.
Boiling water
For kitchen sink clogs caused by grease or soap buildup, carefully pouring boiling water down the drain in two or three stages can help break it up. Don't use this method on PVC pipes — the heat can soften the fittings over time.
Baking soda and vinegar
Pour half a cup of baking soda down the drain, follow it with half a cup of white vinegar, and let it fizz for about 15 minutes before flushing with hot water. It won't dissolve a serious clog, but it can help with mild buildup and leave things smelling better in the process.
Clean the P-trap
The P-trap is the curved pipe under your sink. It's designed to hold water and block sewer gases, but it's also where hair, soap scum, and debris tend to collect. Put a bucket underneath, unscrew the slip joints, and clear out whatever's in there. It's easier than it sounds and fixes a surprising number of slow drains.
What to Skip
Chemical drain cleaners
Products like Drano and Liquid-Plumr are tempting because they're easy, but they cause more problems than they solve. The chemicals are harsh enough to eat through grease — and over time, they can eat through your pipes too, especially older ones. They also don't work on solid clogs like hair or tree roots, and they can make things worse by creating a pool of caustic liquid your plumber then has to work through. We'd recommend skipping them entirely.
Drain snaking without experience
A basic hand snake from the hardware store can work on simple clogs, but if you're not comfortable using one, it's easy to scratch your pipes, push the clog further down, or miss it entirely. If the plunger didn't work, it's usually better to call at this point.
Signs It's Time to Call a Plumber
DIY fixes have their limits. Here's when a clog has moved beyond what a plunger or some baking soda can handle:
Multiple drains are backing up at once. If your toilet, sink, and tub are all slow or gurgling at the same time, the clog isn't in an individual drain — it's in your main sewer line. That requires professional equipment to clear.
Water is coming back up. If water backs up into your tub when you flush the toilet, or into your sink when you run the dishwasher, that's a main line issue. Don't keep running water until it's been cleared.
You hear gurgling sounds. Gurgling coming from your drains or toilet when water goes down elsewhere in the house is a sign of a venting or blockage issue deeper in the system.
The clog keeps coming back. If you've cleared the same drain two or three times in recent months, there's something going on below the surface — grease buildup, a partial root intrusion, or a pipe that's starting to deteriorate.
There's a smell. A persistent sewage smell coming from your drains usually means something is either blocked or broken further down the line.
Your home is older. Homes built before the 1980s may still have cast iron or clay sewer lines that are prone to cracking, root intrusion, and collapse. A recurring clog in an older home should be inspected with a camera before it turns into a full replacement.
What a Plumber Will Actually Do
When you call a plumber for a clogged drain, here's what the process typically looks like:
First, they'll figure out where the clog is and what's causing it. For a simple blockage, a professional drain snake (also called a drain auger) can break it up and clear the line quickly. For more stubborn clogs or main line issues, hydro jetting — which uses high-pressure water to blast buildup out of the pipe — is often the most effective solution. If there's any question about pipe condition, a camera inspection lets the plumber see exactly what's going on inside the line without any guesswork.
The goal is always to clear the clog and figure out why it happened — not just push it further down the line.
Don't Wait Too Long
A slow drain today can turn into a sewage backup tomorrow. Water damage from a backed-up line is expensive, disruptive, and entirely avoidable. If you've tried the basics and things aren't improving, or if you're seeing any of the warning signs above, it's worth making the call sooner rather than later.
