10 Signs You Need to Call a Plumber

Understanding when to call a plumber can save homeowners and business owners time, money, and prevent potential disaster. While some plumbing issues might seem minor, they can quickly escalate into significant problems that require expensive repairs. According to HomeAdvisor, the average emergency plumbing visit in the U.S. costs between $150 and $500, making it clear that early intervention can prevent higher bills later. This guide will highlight ten telltale signs that indicate it's time to pick up the phone and call a professional plumber.

1. Unexpected Increase in Water Bill

A sudden spike in your water bill without a corresponding increase in water usage is a clear sign of a hidden leak. Leaks can occur in underground pipes or within walls and may not always be visible. According to the Environmental Protection Agency, fixing easily corrected household water leaks can save homeowners about 10% on their water bills. The EPA also reports that the average household's leaks can waste nearly 10,000 gallons of water each year, making leak detection an important part of protecting both property and utility costs. Regular monitoring of water bills can help identify plumbing issues before they become major repairs.

• Review your monthly water bills for unexpected increases
• Listen for running water sounds to identify hidden leaks
• Regularly inspect your property for wet spots or mold growth

2. Water Pressure Too Low

Low water pressure makes everyday tasks like showering or washing dishes frustrating and time-consuming. This issue can be due to sediment build-up in pipes or more serious problems like a leak or breach in the main water line. The U.S. Geological Survey explains that hard water can cause scale buildup inside water pipes, gradually reducing the interior diameter of the pipe, restricting water movement, and lowering water pressure.

• Clean faucet aerators and showerheads to remove sediment build-up
• Check for leaks around the property
• Consider consulting a licensed plumber if cleaning doesn’t improve water pressure
• Mineral scale inside pipes can restrict water flow and contribute to lower water pressure

3. Slow Drainage

Slow drainage often points to a blockage in your pipes. While over-the-counter drain cleaners can provide a temporary fix, they can also damage your plumbing over time. Professional plumbers use specialized tools to safely remove blockages without harming your pipes.

• Avoid pouring grease or food scraps down the kitchen sink
• Use hair catchers in showers and bathtubs
• Schedule regular drain cleaning to prevent blockages

4. Gurgling Sounds

Gurgling sounds coming from your drains or toilet can indicate a blockage in the vent pipe or sewer line. These sounds are caused by air being trapped and then released, signaling that water flow is being obstructed.

• Check vent pipes for blockages
• Avoid flushing non-degradable items down the toilet
• Call a plumber if gurgling sounds persist

5. No Hot Water

A lack of hot water is often due to issues with your water heater. These problems can range from simple fixes like relighting the pilot light to more complex issues requiring professional diagnosis and repair. According to the U.S. Department of Energy, water heating accounts for about 18% of a home's energy use, making it the second largest energy expense in most households. When a water heater stops working properly, it can affect both comfort and household energy costs.

• Regularly inspect your water heater for signs of rust or leakage
• Flush the water heater tank annually to remove sediment build-up
• Set the thermostat to an appropriate temperature to avoid overheating

6. Water Stains on Walls or Ceilings

Water stains on your walls or ceilings are clear indicators of leaks. These leaks can cause structural damage over time and lead to mold and mildew growth, posing health risks to occupants.

• Inspect areas around fixtures and appliances for leaks
• Paint or wallpaper discoloration can also indicate hidden leaks
• Address leaks promptly to prevent structural damage

7. Frequent Clogs

Frequent clogs in sinks, toilets, or showers can suggest problems deeper within a plumbing system. Persistent clogs may require professional tools and expertise to resolve without damaging pipes. The U.S. Environmental Protection Agency reports that fats, oils, grease, wipes, and certain household products can create sewer blockages, while tree roots entering through defects or openings in sewer lines can also obstruct flow. Recurring problems may therefore require more than clearing the fixture closest to the clog.

• Use strainers in sinks to catch debris
• Do not flush anything other than toilet paper
• Regular professional cleaning can help address recurring buildup
• Keep fats, oils, and grease out of household drains
• Repeated clogs can indicate root intrusion or another blockage farther inside the sewer line

8. Water Doesn’t Stay Hot

If your water heater can’t maintain a consistent hot water supply, it may be failing. Water heaters have a lifespan of about 8-12 years, depending on maintenance and water quality.

• Insulate your water heater and pipes
• Schedule regular water heater maintenance
• Consider upgrading to a more efficient model if problems persist

9. Rusty Water or Pipes

Rusty water or visible rust on pipes can indicate corrosion, which may eventually contribute to leaks, restricted water flow, and changes in water quality. Corroded plumbing should be inspected so deteriorated sections can be repaired or replaced before more serious damage develops. The U.S. Environmental Protection Agency explains that lead particles can attach to the surface of galvanized pipes and may enter drinking water over time, potentially causing elevated lead levels. Regular inspection and appropriate water testing can help determine whether aging plumbing is affecting household water.

• Check pipes for discoloration, flaking, or rust
• Test water quality when corrosion or contamination is suspected
• Replace severely corroded sections of pipe promptly
• Aging galvanized pipes can collect metal particles that may eventually enter drinking water

10. Sewer Odor

A strong sewer odor in or around a property can indicate a damaged sewer line, blocked vent, dry plumbing trap, or another drainage problem that deserves attention. Sewer gas may contain hydrogen sulfide, and OSHA explains that hydrogen sulfide can accumulate in sewers and other poorly ventilated spaces and can be toxic at sufficient concentrations. OSHA also warns that a person’s sense of smell can become less reliable after continued exposure, so odor alone should not be used to judge whether the gas is still present. A plumbing professional can inspect the system and determine where sewer gases may be entering the property.

• Seal cracks or openings where appropriate after identifying the source
• Ensure plumbing vent pipes are clear of obstructions
• Schedule a sewer line inspection if persistent foul odors develop
• Avoid relying on smell alone to determine whether hydrogen sulfide is present
• Persistent sewer odors warrant prompt inspection of drains, traps, vents, and sewer piping
