Clogged drains, slow water flow, or strange gurgling sounds from your pipes? These are common signs your home’s plumbing system needs a thorough cleaning. But before you call a plumber, you’re probably wondering: how much does it cost to clean house plumbing system? The answer isn’t one-size-fits-all—but with the right info, you can budget wisely and avoid costly surprises. Let’s break it down clearly and practically.
What Exactly Is “Cleaning a House Plumbing System”?
Before diving into costs, it’s important to understand what this service entails. Cleaning a house plumbing system typically involves removing buildup—like grease, hair, soap scum, mineral deposits, or even tree roots—from your pipes to restore proper water flow and prevent future blockages.
This can range from simple drain snaking for a single fixture to hydro jetting the entire main sewer line. The scope directly affects the price.
According to the HomeAdvisor 2025 True Cost Report, most homeowners spend between $175 and $600 for professional plumbing cleaning, depending on method and severity.
How Much Does It Cost to Clean House Plumbing System? (By Service Type)
Here’s a detailed breakdown of average costs based on common cleaning methods:
💡 Pro Tip: Hydro jetting is often worth the extra cost—it uses high-pressure water (up to 4,000 PSI) to scour pipe interiors clean, unlike snaking which only punches a hole through the clog.
What Factors Affect the Cost?
Several variables influence pricing. Understanding these helps you anticipate charges and avoid overpaying.
1. Type of Plumbing System
Older homes with galvanized steel pipes tend to accumulate more corrosion and require gentler (but pricier) methods.
PVC or copper systems respond better to standard cleaning.
2. Location & Accessibility
If your main cleanout is buried or behind a wall, labor costs increase.
Multi-story homes may incur higher fees due to complexity.
3. Severity of Clog
A minor kitchen sink backup costs far less than a main sewer line blocked by tree roots.
Emergency calls (evenings/weekends) often include a 20–50% surcharge.
Many homeowners consider DIY to save money—but is it safe?
✅ When DIY Works
Minor clogs in a single drain
Using a plunger or manual drain snake ($20–$50 tool)
Natural cleaners like baking soda + vinegar (though limited effectiveness)
❌ When to Call a Pro
Recurring clogs
Multiple slow drains (indicates main line issue)
Foul odors from drains
Water backing up in unexpected places
⚠️ Warning: Overuse of chemical drain cleaners (e.g., Drano) can damage pipes and pose health risks. The U.S. Environmental Protection Agency advises against frequent use due to toxic fumes and pipe corrosion.

Step-by-Step: How Professionals Clean Your Plumbing System
If you hire a pro, here’s what typically happens:
Initial Inspection A camera is inserted into the main line to locate blockages, cracks, or root intrusions.
Method Selection Based on findings, the plumber chooses:
Snaking for isolated clogs
Hydro jetting for full-line cleaning
Hydro Jetting Process (if needed)
Connects a high-pressure hose to your cleanout port
Uses 3,500–4,000 PSI water at 22–28°C (72–82°F) to avoid thermal shock to pipes
Flushes debris backward toward the sewer
Post-Cleaning Verification A second camera run ensures pipes are clear and undamaged.
Preventative Recommendations May suggest enzyme-based monthly treatments or installing a backwater valve.
Most jobs take 1–3 hours, depending on complexity.

FAQ Section
Q1: How often should I clean my house plumbing system?
A: Most experts recommend professional cleaning every 1.5 to 2 years. However, if you have trees near sewer lines, hard water, or an older home, annual cleaning may be wise.
Q2: Can I clean my main sewer line myself?
A: Not safely. Main lines require specialized equipment like hydro jets and sewer cameras. DIY attempts can cause pipe damage or sewage backups.
Q3: Does homeowners insurance cover plumbing cleaning?
A: Typically no—routine maintenance isn’t covered. However, if a sudden blockage causes water damage, part of the repair might be covered. Always check your policy.
Q4: What’s the difference between snaking and hydro jetting?
A: Snaking pokes a hole through the clog; hydro jetting scrapes the entire pipe interior clean using high-pressure water. Jetting is more thorough and longer-lasting.
Q5: Are there eco-friendly plumbing cleaning options?
A: Yes! Hydro jetting uses only water. Enzyme-based cleaners (like Bio-Clean) break down organic matter naturally and are safe for septic systems.
Q6: How do I know if I need main line cleaning?
A: Signs include:
Multiple slow drains simultaneously
Gurgling toilets
Sewage smell in yard or basement
Water backing up in showers when flushing toilets
Conclusion
Understanding how much it costs to clean house plumbing system empowers you to make smart, budget-friendly decisions. While basic clogs might cost under $100, investing in professional hydro jetting every couple of years can prevent thousands in water damage or pipe replacement.
Don’t wait for a disaster—proactive maintenance keeps your home running smoothly and saves money long-term.
