10 Common Residential Plumbing Problems and How to Prevent Them

October 28, 2025

A well-functioning plumbing system is essential for a comfortable home, but even the most careful homeowners can face plumbing issues. From minor leaks to major pipe bursts, these problems can disrupt daily life and lead to costly repairs if not addressed promptly. Understanding common residential plumbing issues and learning proactive prevention measures can save both money and stress. In this guide, we’ll explore the ten most frequent plumbing problems homeowners encounter and provide practical tips to prevent them, ensuring your home’s plumbing remains reliable and efficient for years to come.

1. Leaky Faucets

Leaky faucets are more than just annoying—they waste water and increase utility bills. Most leaks occur due to worn-out washers or O-rings.

Prevention: Regularly inspect faucets for drips and replace washers or seals as needed to maintain efficiency.

2. Clogged Drains

Hair, soap, grease, and debris can accumulate, leading to slow or blocked drains.

Prevention: Use drain strainers, avoid pouring grease down sinks, and periodically flush drains with hot water to prevent buildup.

3. Running Toilets

A running toilet wastes hundreds of gallons of water daily. Often, the flapper valve is faulty or misaligned.

Prevention: Check the flapper and flush mechanism regularly, and replace any worn components promptly.

4. Low Water Pressure

Low water pressure can stem from pipe corrosion, sediment buildup, or leaks.

Prevention: Clean faucet aerators, check for leaks, and schedule regular inspections to detect issues early.

5. Water Heater Issues

Sediment accumulation, faulty thermostats, or leaking tanks can reduce water heater efficiency.

Prevention: Flush the tank annually, inspect the anode rod, and maintain appropriate temperature settings.

6. Burst Pipes

Frozen pipes in winter or aging pipes can burst, causing severe water damage.

Prevention: Insulate exposed pipes, maintain a stable indoor temperature, and inspect old plumbing for weaknesses.

7. Sewer Line Backups

Tree roots, debris, or pipe damage can block sewer lines, leading to backups and unpleasant odors.

Prevention: Schedule annual sewer inspections and avoid flushing inappropriate items down toilets.

8. Sump Pump Failures

A failed sump pump can result in basement flooding.

Prevention: Test the pump before rainy seasons, keep it clear of debris, and consider a battery backup system.

9. Faucet Corrosion

Over time, mineral deposits and corrosion can affect faucets, reducing flow and causing leaks.

Prevention: Use water softeners if needed and clean faucets regularly to prevent buildup.

10. Garbage Disposal Problems

Jammed or malfunctioning garbage disposals can disrupt kitchen efficiency.

Prevention: Avoid putting fibrous or hard items in the disposal, run cold water while operating it, and clean it regularly with safe methods.
