8 Most Common Plumbing Issues (and How to Fix Them)

Plumbing problems can disrupt daily life and lead to costly repairs if left unaddressed. Understanding common plumbing issues and their solutions can help homeowners take proactive steps to maintain their plumbing system. Here are some of the most frequent plumbing problems and how to fix them.

1. Dripping Faucets

Dripping faucets waste water and increase utility bills. Common causes include:

Worn-out washers or O-rings
Corroded valve seats
Improper faucet installation

Solution: Replacing the washer or O-ring usually fixes the problem. If the issue persists, a professional plumber can diagnose and repair the faucet.

2. Leaky Pipes

Leaky pipes can lead to water damage, mold growth, and high water bills. Causes include:

Clogged drains creating excess pressure
Pipe corrosion
Loose pipe joints
Cracked or broken pipes

Solution: Minor leaks can be patched with pipe tape or epoxy. More severe leaks may require pipe replacement or professional repair.

3. Running Toilets

A running toilet can waste up to 200 gallons of water per day. The most common reasons include:

Faulty flapper valve
Improperly sized flapper chain
Waterlogged float
Worn-out fill valve

Solution: Replacing the flapper valve or adjusting the float can often resolve the issue. If the toilet continues running, a plumber can assess and fix the problem.

4. Low Water Pressure

Low water pressure makes everyday tasks like showering and dishwashing frustrating. Potential causes include:

Mineral buildup in pipes
Hidden leaks in the plumbing system
Issues with the municipal water supply

Solution: Cleaning aerators and showerheads can improve water pressure. If the problem persists, a professional inspection can identify hidden leaks or pipe blockages.

5. Leaking Hose Bibb

Outdoor hose bibbs often crack after exposure to freezing temperatures. This leads to leaks and wasted water.

Solution: Replacing a standard hose bibb with a frost-proof model can prevent future leaks and water damage.

6. Slow or Clogged Drains

A slow drain can indicate minor clogs, while multiple clogged drains may signal a bigger issue in the sewer line. Causes include:

Hair, soap, and grease buildup
Foreign objects lodged in pipes
Tree root intrusion into sewer lines

Solution: A plunger or drain snake can clear minor clogs. For persistent issues, professional drain cleaning or hydro jetting may be necessary.

7. Sump Pump Failure

A failing sump pump can lead to basement flooding. Common causes include:

Power failure
Clogged discharge pipe
Stuck float switch
Pump motor failure

Solution: Regular sump pump maintenance, such as cleaning the intake screen and testing the float switch, can prevent failures. Installing a battery backup ensures operation during power outages.

8. Water Heater Issues

Lack of hot water can be frustrating and is often caused by:

Sediment buildup in the tank
Faulty heating elements
Incorrect thermostat settings
Aging water heater (over 10 years old)

Solution: Flushing the tank annually can remove sediment buildup. If the water heater is old or malfunctioning, replacing it with a newer, energy-efficient model may be the best option.

Preventing Common Plumbing Issues

While some plumbing problems are unavoidable, regular maintenance can reduce the risk of costly repairs. Here are a few tips:

Inspect faucets, pipes, and toilets for leaks regularly.
Avoid flushing anything other than toilet paper.
Schedule annual plumbing inspections.
Insulate exposed pipes to prevent freezing.
Use drain screens to catch debris and prevent clogs.

Understanding common plumbing issues and how to address them can save homeowners time, money, and frustration. While some minor fixes can be handled with DIY solutions, persistent or severe problems should be addressed by a professional plumber.
