5 Signs Your Drains Need Professional Cleaning
(Don't Ignore #3)

📅 May 8, 2025 ⏰ 5 min read 👤 Drain Doctor Plumbing Team

A slow drain is one of those problems it's easy to live with — pour some hot water down, call it good. But slow drains are rarely just slow drains. They're usually the first symptom of something bigger building up inside your pipes. By the time the clog is severe enough to cause a complete backup, you're looking at a much more disruptive repair.

Here are five signs your drains are trying to tell you something — and what to do about each one before it becomes a plumbing emergency.

① Water Drains Slower Than Usual

This is the most obvious sign, and the one most people shrug off. If your kitchen sink takes 30 seconds to drain after washing dishes, or your shower has a small pond forming around your feet, you have a partial clog developing.

Slow drains are caused by grease buildup, hair, soap scum, and debris accumulating on the pipe walls. At first the restriction is small — but it grows over time. A professional drain cleaning removes the buildup completely rather than just poking a temporary hole through it.

② Gurgling Sounds From Drains or Toilets

If you hear gurgling sounds from your toilet after running the bathroom sink, or bubbling from a floor drain when you run the washing machine — that's air being displaced through your drain system.

It means water is having trouble flowing past a partial blockage, so it's pushing air back through the nearest open drain. This is a sure sign that a clog is forming in your main drain line, not just a single fixture. Don't ignore this one — gurgling drains are a step away from a full sewage backup.

③ Sewage or Rotten Egg Smell From Drains

A persistent sulfur or sewage smell coming from your drains — even when you haven't noticed slow drainage yet — is a serious warning sign. That smell is sewer gas (hydrogen sulfide), which escapes through cracks, failed pipe joints, or when a partial blockage traps decomposing waste.

Beyond the unpleasantness, sewer gas is toxic in high concentrations and can be a fire hazard. If you're smelling it regularly inside your home, call a plumber immediately. A camera inspection will identify whether the source is a blockage, a dry P-trap, or a cracked drain line.

This is the sign most homeowners dismiss as "just the drain being smelly" — but it's the one most likely to indicate a problem that's about to get worse fast.

④ Multiple Drains Clogged at Once

One clogged drain is usually a local problem — hair in the shower drain, food in the kitchen sink. But when two or more drains in your home start backing up around the same time, the blockage is almost certainly in your main sewer line.

Toilets are connected closer to the main line than sinks or showers, so if your toilets are also sluggish or gurgling while the sink is slow, that's a strong indicator of a main line problem. A professional hydro-jetting service clears the entire line — not just one fixture at a time.

⑤ Recurring Clogs in the Same Drain

If you've cleared a drain clog yourself — or called a plumber — and the same drain clogs again within a few weeks or months, a simple drain snake isn't solving the real problem.

Recurring clogs in the same location often mean there's a structural issue: a cracked pipe, a sagging section collecting debris, or heavy scale buildup on the pipe walls that keeps catching new material. A camera inspection is the only way to know for certain what's causing the repeat blockage — and what the right fix actually is.

What Should You Do?

If you're seeing one or more of these signs, resist the temptation to pour chemical drain cleaner down the pipe. Store-bought chemical cleaners are caustic and can damage older pipes — and they rarely remove the full blockage. They just dissolve the soft material around the edges and let water trickle through until the blockage closes again.

Professional drain cleaning uses hydro-jetting (high-pressure water) or mechanical snaking to fully clear the pipe. A camera inspection before and after confirms the pipe is truly clean and identifies any structural issues that need attention.

Frequently Asked Questions

Baking soda and vinegar is a gentle, safe option for very minor buildup — it won't damage pipes and is better than chemical cleaners. However, it's not powerful enough to clear an actual clog or remove grease and scale buildup from the pipe walls. Use it as a monthly maintenance rinse, not a clog remedy.
For a typical household, professional drain cleaning every 1–2 years is a good preventive measure. Homes with heavy cooking (grease), older galvanized or clay pipes, or large families may benefit from annual service. If you have mature trees in your yard near your sewer line, consider an annual camera inspection as well.
Hydro-jetting uses high-pressure water (typically 1,500–4,000 PSI) to scour the inside of pipes, removing grease, scale, debris, and even tree roots. It is safe for most pipe materials including PVC, ABS, and cast iron in good condition. We always perform a camera inspection first to confirm the pipe can handle the pressure before jetting.
