The Homeowner’s Guide to Drain Cleaning

Slow drains have a way of getting ignored. You notice the water taking a little longer to clear, make a mental note, and move on. Then a few weeks later it’s worse, and by the time it’s a real problem, whatever was building up in that line has had months to establish itself.

Drain cleaning is one of the most common plumbing services homeowners in Bloomington, Normal, Downs, Le Roy, Heyworth, and surrounding Central Illinois communities call for, and also one of the most misunderstood. This guide covers what’s actually happening when your drains slow down, what you can reasonably handle yourself, and when it’s time to bring in a professional.

What Causes Drains to Slow Down

Most drain problems come down to accumulation, but the type varies depending on where in the house you’re dealing with it.

Kitchen Drains

Grease is the primary culprit for kitchen drain clogs. Even small amounts of cooking fat rinsed down the drain cool, solidify, and stick to pipe walls. Dish soap and food particles then layer on top of that grease buildup over time, gradually narrowing the line.

Bathroom Drains

Hair, soap residue, and mineral deposits from hard water are the usual contributors. These tend to accumulate at the drain opening and in the P-trap first, which is why bathroom clogs are often the easiest to address early and the most stubborn when left alone.

Main Sewer Lines

Tree root intrusion, grease accumulation from multiple fixtures, and deteriorating pipe material are all common in older homes throughout Central Illinois. When a main line slows down, it affects every drain in the house, which is a different problem than a clogged kitchen sink.

How to Handle a Drain Clog Yourself

Not every slow drain needs a plumber. For minor, localized clogs, here are a few DIY approaches worth trying first:

• Plunger: Works well for toilet clogs and simple sink blockages when the obstruction is close to the surface. Create a proper seal and use consistent pressure rather than rapid, shallow strokes.
• Manual removal: For bathroom sink and tub drains, the issue is often a visible accumulation of hair just below the drain cover. Removing the stopper and clearing that material manually solves the problem more reliably than any chemical treatment.
• Chemical drain cleaners: These can dissolve soft clogs but aren’t a solution for anything structural. Repeated use can damage certain pipe materials over time. They’re a reasonable occasional tool for minor buildup, not a maintenance strategy.

If you’ve tried the basics and the drain is still slow, or if multiple drains in the house are sluggish at the same time, these are signs it’s time to hire a professional drain cleaning company. 

What to Do If a Drain Clog Keeps Coming Back

A drain that clogs repeatedly in the same place is telling you something. If a kitchen drain has needed cleaning three times in two years, the issue is either significant buildup that a basic snake isn’t fully clearing, or something structural further down the line.

The same applies to mainline backups. Homes in Central Illinois with mature trees nearby are particularly prone to root intrusion in sewer laterals. Roots don’t clear on their own, and a snake that restores flow through a root mass creates a temporary path through them rather than removing them entirely. 

Professional drain cleaning, followed by a camera inspection, is a more complete approach to managing stubborn clogs.

What Professional Drain Cleaning Actually Involves

There’s a meaningful difference between snaking a drain and cleaning it. A lot of homeowners have had a plumber run a cable through a clogged line, restore flow, and consider the job done. That works for a simple, one-time obstruction. It’s not a complete solution when buildup along the pipe walls is the underlying issue.

Professional drain cleaning typically involves one of two approaches: snaking or hydro-jetting. In most cases, it’s also accompanied by a pre- and post-clean camera inspection.

Snaking

Snaking uses a flexible auger to break through or retrieve a blockage. It’s fast, effective for isolated clogs, and the right call when the problem is straightforward. A drain that clogs occasionally and clears easily with a snake probably doesn’t need more than that.

Hydro-Jetting

Hydro-jetting is a more thorough process. High-pressure water scours the inside of the pipe, removing grease, scale, soap residue, and soft root growth from the pipe walls rather than just punching through the obstruction. For lines with significant buildup or a history of recurring clogs, hydro-jetting provides a longer-lasting result. It’s also the standard prep step before any trenchless sewer repair work.

Camera Inspections

For mainline issues, a camera inspection before and after cleaning gives you a clear picture of what was causing the problem and whether the cleaning resolved it completely. If there’s root intrusion, joint separation, or pipe damage contributing to the backup, you’ll want to know that before assuming a cleaning is the whole answer.

What Professional Drain Cleaning Costs

Drain cleaning costs vary depending on the type of service, the location of the blockage, and whether a camera inspection is part of the visit. A few general patterns worth knowing:

Covenant Plumbing offers mainline drain cleaning starting at $109, which includes a free camera inspection so you can see exactly what’s in your line before and after the work is done. For more involved situations, such as significant root intrusion or buildup that requires hydro-jetting rather than basic snaking, costs will be higher based on the scope of the job.

For homeowners dealing with recurring drain problems, the cost of periodic professional cleaning is almost always less than the cost of letting buildup progress to the point of a main line failure or backup. A plumber can give you an accurate estimate after evaluating your specific situation.

Keeping Drains Clear Between Service Calls

Generally speaking, it’s good practice to schedule professional drain cleaning annually. A few habits make a real difference in how often you’ll deal with drain problems and help keep your pipes running smoothly between service calls:

1. Skip the grease. Avoid putting grease, fat, or starchy foods down the drain regardless of whether you have a garbage disposal. Disposals handle food waste, not grease.
2. Use a drain cover. A simple mesh cover in bathroom drains catches hair before it accumulates in the line. It’s one of the cheapest and most effective preventive measures available.
3. Be selective about what gets flushed. Avoid flushing anything other than toilet paper. Wipes marketed as “flushable” don’t break down the way toilet paper does and are a leading cause of main line blockages.
4. Consider enzyme treatments. For homes with a history of grease buildup in kitchen lines, enzyme-based drain treatments used monthly can help keep accumulation manageable between professional cleanings.

None of these eliminate the need for occasional professional service, but they extend the intervals considerably.
