Plumbing problems rarely announce themselves politely. One day everything works fine, and the next you are standing in ankle‑deep water or wondering why the shower barely drips. Almost every homeowner will face plumbing issues at some point. The good news is that many problems start small and can be managed if you understand what is happening.
This guide walks you through the most common plumbing issues, how to fix minor ones safely, and when it is better to call a professional plumber instead of fixing he issue by yourself. Whether you are a homeowner or someone who likes to understand systems in detail, this blog is designed to help you make confident decisions.
Clogged Drains and Toilets
Common Causes
Clogs happen when materials build up inside pipes over time. In kitchens, grease, food scraps, and soap residue are the usual suspects. In bathrooms, hair, soap scum, and excess toilet paper are common causes.
Example: Some people pour cooking oil down the sink, not realizing it cools and hardens inside the pipes. Months later, water starts draining slowly, then stops altogether.
What You Can Try
- Use a plunger to loosen the blockage. Make sure there is enough water to create a seal.
- Pour hot water mixed with dish soap down the drain for grease clogs.
- Use a basic drain snake to pull out hair and debris.
When to Call a Professional
If clogs keep coming back, affect multiple drains, or cause toilet overflows, the issue may be deeper in the system. A professional plumber can inspect the line and clear it properly without damaging pipes.
Dripping Faucets
A dripping faucet may seem minor, but it wastes water and raises utility bills. Even a slow drip can waste hundreds of gallons a year.
Common Causes
- Worn washers or seals
- Loose components
- Corroded valve parts
What You Can Try
In many cases, replacing a washer or cartridge solves the problem. Turn off the water supply, disassemble the faucet, and replace the worn part.
When to Call a Professional
If the faucet is old, corroded, or continues dripping after repairs, replacement may be more cost‑effective. Alexander Plumbing LLC can help assess whether repair or replacement makes more sense.
Running Toilets
A running toilet often sounds like water constantly refilling the tank. This issue can silently waste a large amount of water every day.
Common Causes
- Faulty flapper valve
- Improper float level
- Worn fill valve
What You Can Try
- Remove the tank lid.
- Check if the flapper seals properly.
- Adjust the float to stop overfilling.
When to Call a Professional
If replacing parts does not stop the running or the toilet is very old, a plumber can recommend upgrades that improve efficiency.
Low Water Pressure
Low water pressure makes everyday tasks frustrating, from showering to washing dishes.
Common Low Water Pressure Causes
- Mineral buildup in fixtures
- Hidden leaks
- Aging pipes
- Municipal supply issues
What You Can Try
Clean faucet aerators and showerheads by soaking them in vinegar to remove mineral buildup.
When to Call a Professional
If pressure is low throughout the home, the issue may involve pipe corrosion or leaks. A plumber can test pressure levels and identify the root cause.
Leaky Pipes
Leaks can cause serious water damage if ignored.
Signs of a Leak
- Damp walls or ceilings
- Musty smells
- Unexpected water bill increases
Temporary Fix
Pipe repair tape or clamps can slow a leak temporarily, but they are not long‑term solutions. Hidden leaks behind walls or under floors require professional repair to prevent mold and structural damage.
Water Heater Problems
Water heater issues can quickly disrupt daily routines, affecting everything from showers and laundry to dishwashing and cleaning.
Common Issues
- Sediment buildup
- Faulty heating elements
- Thermostat issues
Basic Maintenance Tip
Flushing the tank once a year can help extend the life of a traditional water heater.
When to Call a Professional
If water temperature is inconsistent, the unit leaks, or the heater is over ten years old, professional water heater service is recommended.
Dirty or Discolored Water
Seeing brown, yellow, or rusty-looking water can be concerning and is often a sign of an underlying plumbing issue that should not be ignored.
Common Causes
- Pipe corrosion
- Sediment in the water heater
- Municipal water work
What to Do
Run the water for a few minutes to check if the discoloration clears. If the water remains discolored, avoid using it for drinking or cooking and contact a professional plumber to identify the source of the problem.
Frozen Pipes
Frozen pipes are a common problem in colder climates and can cause serious damage when the ice inside expands and the pipe bursts during thawing.
Prevention Tips
- Insulate exposed pipes
- Keep cabinet doors open in winter
- Let faucets drip during extreme cold
When to Call a Professional
If a pipe has burst or you cannot locate the freeze, professional help is necessary.
Garbage Disposal Clogs
Garbage disposals are helpful kitchen tools, but they are not designed to handle every type of food waste. Putting the wrong items down the disposal can quickly lead to clogs or damage.
Common Causes
- Fibrous foods like celery
- Grease and fats
- Large food scraps
What You Can Try
Before doing anything, turn off the power to the disposal. Use a hex key to manually rotate the disposal from underneath, then flush the system with cold water to help clear remaining debris.
When to Call a Plumber
Call a professional plumber if the garbage disposal:
- Continues to clog after basic troubleshooting
- Makes unusual grinding or humming noises
- Leaks from underneath the sink
- Will not turn on or keeps tripping the breaker
These signs often point to deeper plumbing or electrical issues that require professional repair to avoid further damage.
Sewer Line Blockages
Sewer line blockages affect the entire plumbing system and can quickly lead to messy, unhealthy conditions if not addressed promptly.
Warning Signs
- Multiple drains backing up
- Sewage smells
- Gurgling sounds
What You Can Try First
- Stop using water to prevent further backups
- Check the main cleanout for visible blockages
- Use a plunger on the lowest drain or toilet if the backup is minor
Avoid chemical drain cleaners, as they can damage pipes and often make sewer problems worse.
When to Call a Professional
These issues typically require professional sewer line service, as specialized tools and experience are needed to safely locate the blockage and prevent further damage.
