A practical, Boise-homeowner guide to keeping drains flowing
Slow sinks, gurgling tubs, and surprise backups usually don’t start as emergencies—they start as small restrictions that build over time. In Boise and the Treasure Valley, everyday habits (grease in the kitchen, hair in the shower, “flushable” wipes, and mineral scale) can quietly narrow your pipes until the day water stops moving. This guide explains what causes most clogs, what you can safely do at home, and when professional drain cleaning is the smart (and damage-preventing) move.
What actually causes most clogs?
Most drain problems come down to two categories: stuff that shouldn’t be in the pipe and buildup that gradually coats the pipe. In real homes, it’s often a combination—hair catches soap scum, grease grabs food particles, and the “small” clog becomes a full blockage.
Common culprits we see in Boise-area homes:
- Fats, oils, and grease (FOG): Grease cools and hardens inside pipes, restricting flow and increasing backup risk. Even running hot water doesn’t “fix” it—once it cools downstream, it can still stick and accumulate.
- Hair + soap scum: The classic shower/tub clog combo. Hair acts like a net; soap scum binds it into a dense mat.
- “Flushable” wipes & paper products: These can hang up on rough spots, roots, or pipe joints and form a plug.
- Food scraps & coffee grounds: Garbage disposals don’t make solids “disappear.” They can settle and combine with grease.
- Mineral scale: Hard-water minerals can coat the inside of pipes and reduce diameter over time, making clogs more likely.
Why drain issues escalate fast (and get expensive)
A partial blockage doesn’t just slow water—it changes how your plumbing behaves. Water starts to swirl and leave residue behind, solids settle out, and the clog “grows.” In the worst cases, pressure and backups can force wastewater into fixtures on lower floors, or flood areas around floor drains.
Red flag: If multiple fixtures are slow at the same time (example: toilet bubbles when the shower drains), the problem may be deeper in the main line—not just one trap under a sink.
DIY vs. professional drain cleaning: what’s safe and what works
| Approach | Best for | Pros | Risks / Limits |
|---|---|---|---|
| Drain strainer + routine cleaning | Hair, food solids prevention | Low cost, high impact | Prevention only; won’t clear existing deep clogs |
| Plunger (correct type) | Toilets, some sinks/tubs | Fast, safe when used correctly | Can’t remove buildup; may not reach past branch lines |
| Hand auger / small snake | Localized clogs (sink, tub) | Physically removes hair/solids | Can scratch fixtures, damage older piping if forced |
| Enzyme drain products | Maintenance (light organic buildup) | Gentler for routine use | Not a “clog remover” for heavy grease, wipes, roots, scale |
| Professional cable + inspection | Recurring clogs, deeper lines | Finds the cause; clears blockages reliably | Requires a licensed plumber to avoid pipe/fixture damage |
| Hot water jetting | Grease, sludge, heavy buildup | Scours pipe walls; excellent for recurring grease issues | Should be evaluated first to ensure piping is suitable |
What to do when a drain is slow (a safe checklist)
If water is still draining (just slowly), you have a window to handle it before it becomes a full blockage.
Step-by-step: quick triage
- Identify the scope: Is it one fixture, one room, or the whole house? Multiple slow drains often suggests a main line issue.
- Remove the easy stuff: Pull and clean the drain stopper/strainer and remove visible hair and debris (gloves help).
- Use the right plunger: Cup plunger for sinks/tubs; flange plunger for toilets. Seal overflow openings for better pressure on tubs.
- Try a small hand auger (if appropriate): Useful for tub/shower hair clogs and some sink blockages. Go gently—don’t force it.
- Skip harsh chemical drain cleaners: They can be hard on plumbing and create a safety hazard for whoever has to service the line afterward.
- Call a pro if it returns within days/weeks: Recurring clogs usually mean buildup, a damaged section, or a deeper obstruction that needs proper equipment.
Did you know?
- Pouring grease down the drain—even with hot water—can still lead to clogs and sewer backups once the grease cools and sticks to pipe walls.
- Garbage disposals don’t prevent grease buildup; they only shred solids into smaller solids that can still accumulate.
- Many sewer agencies recommend wiping greasy pans and scraping plates into the trash to reduce FOG entering plumbing.
Simple habit changes in the kitchen and bathroom prevent a large share of emergency drain calls—especially when combined with periodic professional maintenance for older homes or recurring problem lines.
Drain clog prevention tips that actually work
Kitchen drains: keep grease and solids out
- Trash the grease: Let grease cool in a disposable container, seal it, and put it in the trash—not the sink.
- Wipe first, wash second: Wipe greasy pans and plates with paper towels before rinsing.
- Use a sink strainer: Catch rice, pasta, coffee grounds, and food scraps before they enter the drain.
- Be cautious with the disposal: Use it sparingly; it’s not a replacement for scraping the plate.
Bathroom drains: stop hair before it becomes a blockage
- Install a hair catcher: This is the single easiest way to reduce shower/tub clogs.
- Clean stoppers routinely: Remove and clean tub/sink stoppers monthly (more often for long hair).
- Know what not to flush: Wipes, paper towels, feminine products, and cotton items belong in the trash.
Recurring clogs: consider a preventive clean-out
If you’re clearing the same drain every few months, the line may have buildup (grease, sludge, scale) or an underlying issue. Professional drain cleaning—especially hot water jetting for stubborn buildup—can restore flow by scouring pipe walls rather than just poking a hole through the clog.

A Boise, Idaho angle: when to be extra cautious
Boise homes range from mid-century builds to newer neighborhoods across the Treasure Valley. Older sections of plumbing can have more scale, rougher interiors, or past repairs that snag debris. Cold snaps can also add stress to plumbing systems, and emergency calls often spike when a small restriction turns into a full backup at the worst time.
When Boise homeowners should call sooner rather than later
- You smell sewage near a drain or in a basement/crawlspace
- Toilet bubbles when a sink or shower drains
- Water backs up into a tub/shower when running the washer
- Clogs return quickly after plunging or snaking

FAQ: Drain cleaning services
How do I know if the clog is in the main sewer line?
Watch for multiple drains slowing at once, gurgling sounds, or water backing up in a tub/shower when you flush or run the washer. Those symptoms often point to a deeper issue than a single sink trap.
Is hot water jetting safe for my pipes?
In many cases, yes—when it’s performed by a professional after evaluating the line. Jetting is especially effective for grease and heavy buildup because it cleans the pipe walls rather than just pushing through a hole in the clog.
Should I use chemical drain cleaner from the store?
It’s usually not the best first step. Harsh chemicals can be hard on plumbing and create safety hazards during repairs. If a clog is recurring or severe, professional mechanical cleaning is typically the safer, more reliable approach.
Why do my drains clog again shortly after I snake them?
Snaking can punch through the center of a clog while leaving buildup on the pipe walls. That leftover residue catches more debris quickly. A deeper clean (and sometimes inspection) helps address the real cause.
Do you offer emergency drain cleaning in Boise?
Yes—if you have a backup or overflow risk, it’s time to treat it like an emergency. Use Cloverdale Plumbing’s emergency page for fast help: Emergency Services.
