Few household annoyances are as universal as a slow drain. The sink that takes a beat too long to empty. The shower that leaves you standing in an inch of water. The kitchen sink that gurgles and backs up right when you’ve got a counter full of dishes. Most of the time, a clog is a small, fixable problem — and often one you can handle yourself.
But not always. Some clogs are a warning sign of something bigger in the line, and a few common “fixes” do more harm than good. Here’s how to tell what you can clear on your own, what to skip, and when it’s time to call a pro.
Key Points
- Most single slow drains are local clogs you can clear with simple tools — no chemicals required.
- A plunger, a drain snake, and the baking-soda-and-hot-water approach handle the majority of everyday clogs.
- Chemical drain cleaners can damage pipes and rarely fix the real problem — we recommend skipping them.
- Multiple drains backing up at once, or recurring clogs, usually point to a main-line issue that needs a pro.
- St. Louis’s older homes and mature trees make sewer-line and root intrusion problems more common than you’d expect.
First, Figure Out What Kind of Clog You Have
Before you reach for any tool, notice the pattern — it tells you almost everything:
- One slow drain. A single sink, tub, or shower draining slowly almost always means a local clog close to that fixture — hair, soap scum, grease, or food. This is the most DIY-friendly situation.
- Multiple drains slow at once. If the kitchen sink, bathroom sink, and tub are all sluggish, the problem isn’t at any one fixture — it’s further down the shared line. That’s a pro situation.
- Gurgling or backing up elsewhere. Run the bathroom sink and the toilet gurgles? Flush the toilet and the tub backs up? Those are signs of a partial main-line blockage — stop and call.
- Sewage smell or backup. Any sewage odor or wastewater coming up where it shouldn’t is a call-now situation, not a DIY one.
What You Can Safely Fix Yourself
For a single slow or clogged drain, here’s the order we’d try things — cheapest and gentlest first:
- Clear the visible blockage. For sinks and tubs, the culprit is often hair and gunk just below the stopper. Remove the stopper, pull out what you can reach (a bent wire or a cheap plastic drain-cleaning tool works well), and you’ve solved a lot of clogs right there.
- Try hot water and baking soda. Pour a pot of hot — not boiling, if you have PVC pipes — water down, follow with about a half-cup of baking soda, then a cup of vinegar, let it fizz, and flush with more hot water. Good for grease and soap buildup.
- Plunge it. A cup plunger works on sinks and tubs, not just toilets. Block any overflow opening with a wet rag first so you get real suction, and give it firm, repeated pushes.
- Snake it. A hand-operated drain snake (auger) is inexpensive and handles clogs deeper than you can reach by hand. Feed it in, turn to catch the clog, and pull it back out.
- Clean the P-trap. The curved pipe under a sink catches debris and is designed to come apart. Put a bucket underneath, unscrew the slip nuts, clean it out, and reassemble. This clears a lot of stubborn kitchen and bathroom sink clogs.
Dr. Steve’s Take:
Dr. Steve has made the point for years that the cheapest tools a plunger, a hand snake, a little patience solve the large majority of household clogs, and that the harsh chemical “miracle” products often create more expensive problems than they solve.

What to Skip: A Word on Chemical Drain Cleaners
It’s tempting to pour in a bottle of chemical drain cleaner and walk away. We’d steer you away from it. Those products rely on harsh caustic or acidic reactions that can corrode older pipes — and St. Louis has plenty of older pipes. They often only punch a small hole through a clog rather than clearing it, so the problem returns. And if the chemical doesn’t work and a pro has to open the line, they’re now dealing with a pipe full of caustic liquid. A plunger and a snake are safer, cheaper, and more effective.
When to Call a Pro
Hand off the job when you see any of these:
- More than one drain is slow or backing up. That points to the shared line, not a fixture — beyond a hand snake’s reach.
- The clog keeps coming back. A drain you’ve cleared two or three times is telling you the real blockage is deeper or larger than a surface clog.
- Gurgling, sewage smell, or water coming up elsewhere. Classic signs of a main-line or sewer problem.
- You’ve snaked it and it’s still slow. If your tools didn’t reach it, it’s time for someone with longer ones.
- Anything involving opening walls or the main sewer line. That’s well past handyman scope and into licensed plumbing or sewer territory — we’ll tell you when you’re there.
Why St. Louis Drains Clog More Than You’d Think
Our housing stock skews old, and so do the pipes underneath it. Many St. Louis homes still have aging cast-iron or clay sewer lines that scale up, crack, and snag debris over the decades. Add the city’s mature trees — those gorgeous old oaks and maples — and you get root intrusion, where roots find a hairline crack in the line and grow into it, catching everything that flows past. A clog that keeps returning in an older St. Louis home is often roots or a failing line, not just grease. That’s a diagnosis worth having before you keep snaking the same drain.
