10 Common Plumbing Problems Every Homeowner Should Know

As a homeowner, plumbing issues are inevitable. From minor annoyances to major emergencies, understanding common plumbing problems can save you time, money, and stress. This guide covers the top 10 plumbing issues you're likely to encounter, along with practical tips for prevention and when to call in the professionals.

1. Dripping Faucets

That persistent drip-drip-drip isn't just annoying—it's wasteful. A single dripping faucet can waste hundreds of gallons of water annually, significantly increasing your water bill.

Common causes: Worn-out washers, O-rings, or valve seats that need replacement.

DIY tips: For compression faucets, turn off water supply lines, disassemble the handle, and replace the washer. For cartridge or ceramic disk faucets, consult your manufacturer's guide for specific replacement parts.

When to call a pro: If dripping continues after replacement or if you're uncomfortable with disassembly.

2. Slow Draining Sinks

When water takes forever to drain from your sink, you likely have a partial clog developing in your pipes.

Common causes: Accumulation of hair, soap scum, food particles, or grease.

DIY tips: Try a plunger or a homemade solution of baking soda followed by vinegar. For ongoing maintenance, use drain strainers to catch debris and avoid pouring grease down drains.

When to call a pro: If multiple drains are slow simultaneously (indicating a main line issue) or if DIY methods fail.

3. Clogged Toilets

Toilet clogs range from minor obstructions to complete backups that can cause overflow and water damage.

Common causes: Flushing inappropriate items (wipes, feminine products, excessive toilet paper) or mineral buildup in older pipes.

DIY tips: Use a flange plunger for better seal and pressure. Avoid chemical drain cleaners which can damage pipes. For stubborn clogs, a toilet auger can often reach deeper obstructions.

When to call a pro: If plunging and augering don't work, or if you notice water backing up in other drains when you flush.

4. Running Toilets

A running toilet can waste up to 200 gallons of water per day—that's like flushing your money down the drain!

Common causes: Faulty flapper valves, improperly adjusted float arms, or fill valve issues.

DIY tips: Remove tank lid and check the flapper for wear or misalignment. Adjust the float arm to ensure proper water level. Food coloring in the tank can help identify leaks into the bowl.

When to call a pro: If simple adjustments don't solve the problem or if you suspect more complex internal mechanism issues.

5. Low Water Pressure

Weak water flow can turn simple tasks like showering or washing dishes into frustrating experiences.

Common causes: Aerator clogging, sediment buildup in pipes, or more serious issues like pipe corrosion or leaks.

DIY tips: Clean faucet aerators by unscrewing and rinsing out mineral deposits. For showerheads, soak in vinegar overnight to dissolve buildup.

When to call a pro: If low pressure affects multiple fixtures throughout your home, indicating possible pipe scale or system-wide issues.

6. Leaky Pipes

Pipe leaks can cause significant water damage, mold growth, and structural issues if left unaddressed.

Common causes: Corrosion, joint damage, excessive water pressure, freezing temperatures, or physical impact to pipes.

DIY tips: For temporary fixes, use pipe tape or epoxy compounds. Know your main water shut-off valve location for emergencies. Insulate pipes in unheated areas to prevent freezing.

When to call a pro: For any significant or recurring leaks, or if you notice water stains on walls/ceilings indicating hidden leaks.

7. Water Heater Issues

From no hot water to strange noises, water heater problems can disrupt your daily routine.

Common causes: Sediment buildup, faulty heating elements, thermostat issues, or tank corrosion.

DIY tips: Drain a few gallons from the tank annually to flush sediment. Test the pressure relief valve periodically. Adjust thermostat settings (typically 120°F for optimal efficiency).

When to call a pro: For gas line issues, electrical problems, major leaks, or if your water heater is over 10 years old and experiencing frequent issues.

8. Sewer System Backup

This is every homeowner's nightmare—multiple drains backing up simultaneously, often with unpleasant odors.

Common causes: Tree root intrusion, pipe collapse, severe clogs, or problems with the municipal sewer line.

DIY tips: Limited—sewer issues typically require professional equipment. Prevent problems by avoiding flushing non-degradable items and having regular inspections if you have mature trees near sewer lines.

When to call a pro: Immediately if multiple fixtures back up simultaneously, you notice sewage odors, or water backs up in floor drains.

9. Garbage Disposal Jams

A stuck disposal can leave you with a messy sink and potential drainage issues.

Common causes: Overloading, improper items (fibrous vegetables, bones, grease), or foreign objects.

DIY tips: Use an Allen wrench in the reset hole at the bottom of the unit to manually turn the blades. Press the reset button. Never put your hand in the disposal.

When to call a pro: If the disposal hums but doesn't work, makes grinding noises, or repeatedly trips the circuit breaker.

10. Sump Pump Failure

For homes with basements or crawl spaces, sump pump failure during heavy rain can lead to catastrophic flooding.

Common causes: Power outages, switch problems, clogged discharge lines, or pump burnout.

DIY tips: Test your sump pump monthly by pouring water into the pit. Ensure the discharge line is clear and directs water away from your foundation. Consider a battery backup system.

When to call a pro: For installation, major repairs, or if your pump runs continuously during dry weather.

Prevention Is Key

Regular maintenance can prevent many common plumbing problems:

• Schedule annual plumbing inspections
• Know the location of your main water shut-off valve
• Avoid chemical drain cleaners that can damage pipes
• Use drain strainers in all sinks and showers
• Never flush anything besides toilet paper and human waste
• Insulate pipes in unheated areas before winter

When DIY Isn't Enough

While many minor plumbing issues can be handled with basic tools and knowledge, some situations require professional expertise. If you encounter any of the following, it's time to call in the experts:

• Major leaks or pipe bursts
• Sewer line backups
• No water throughout the house
• Gas line issues (evacuate immediately and call professionals)
• Problems that persist after your repair attempts
