If you’ve ever woken up to a flooded kitchen or dealt with a sink that won’t drain, you know how stressful plumbing issues can be. Left unchecked, small leaks or clogs can lead to thousands of dollars in water damage—the average U.S. household loses nearly 10,000 gallons of water annually due to leaks, according to the EPA . In this guide, we’ll walk you through the 5 common plumbing problems and how we fix them, with practical, step-by-step solutions that balance DIY safety and when to call a pro.
1. Dripping Faucets: Annoying But Costly
Why does my faucet keep dripping?
A dripping faucet isn’t just irritating—it’s wasteful. The U.S. Geological Survey estimates that a single leaky faucet dripping once per second can waste over 3,000 gallons of water per year.
Common Causes:
- Worn-out washer or O-ring
- Corroded valve seat
- Loose parts
How We Fix It:
- Turn off the water supply under the sink.
- Disassemble the faucet handle using a screwdriver or Allen wrench.
- Inspect the washer and O-ring—replace if cracked or brittle (standard size: 3/8 inch).
- Clean the valve seat with vinegar to remove mineral buildup.
- Reassemble and test.
💡 Pro Tip: Use plumber’s grease when reassembling to extend part life.
If the drip persists after replacement, the cartridge may need professional servicing—especially in ceramic-disc faucets.
2. Clogged Drains: From Slow to Stopped
Why won’t my sink or shower drain?
Hair, soap scum, grease, and food debris are the usual suspects. The International Association of Certified Home Inspectors notes that kitchen and bathroom drains account for 70% of all residential clogs.
How We Fix It (Safely & Effectively):
For Minor Clogs:
- Baking Soda + Vinegar Method:
- Pour ½ cup baking soda down the drain.
- Follow with 1 cup white vinegar.
- Cover the drain for 15 minutes.
- Flush with 2 liters of hot (not boiling) water at 50–60°C (122–140°F).
For Stubborn Clogs:
- Plunger: Use a cup plunger for sinks; a flange plunger for showers. Apply 10–15 firm pumps.
- Drain Snake: Insert a 15–25 ft hand auger, rotate clockwise, and retrieve debris.
⚠️ Avoid chemical drain cleaners like Drano—they corrode pipes over time and pose health risks. According to Wikipedia , many contain sodium hydroxide or sulfuric acid, which can damage PVC and older metal pipes.
3. Running Toilets: The Silent Water Waster
Why does my toilet keep running after flushing?
A running toilet can waste up to 200 gallons of water per day. Often, it’s due to a faulty flapper or fill valve—both inexpensive to replace.
Diagnosis & Fix:
- Add a few drops of food coloring to the tank. Wait 15 minutes. If color appears in the bowl, the flapper is leaking.
- Turn off water, flush to empty the tank.
- Replace the flapper (standard universal size: 2–3 inch) – costs under $5.
- Adjust the float so the water shuts off 1 inch below the overflow tube.
When to Call a Pro: If the fill valve (the tall mechanism on the left) hisses continuously or leaks at the base, replacement may require plumbing expertise.
4. Low Water Pressure: Weak Flow, Big Frustration
Why is my shower pressure so low?
Low pressure can stem from municipal supply issues—but 80% of the time, it’s localized to your home, per the Plumbing-Heating-Cooling Contractors Association.
Common Causes & Fixes:
| Clogged aerator | Unscrew faucet head, soak in vinegar for 1 hour, scrub with toothbrush | No |
| Partially closed shutoff valve | Ensure main & fixture valves are fully open | No |
| Pipe corrosion (older homes) | Flush system or replace sections | Yes |
| Pressure-reducing valve failure | Adjust or replace PRV (usually near main water line) | Yes |
Start by cleaning all aerators—this solves 60% of cases. If pressure is low only in hot water, your water heater may need flushing.
5. Leaky Pipes: Don’t Ignore the Drip
What causes pipes to leak, and how serious is it?
Leaks often start at joints or from pipe corrosion. The Insurance Institute for Business & Home Safety reports that water damage from plumbing failures is the #2 cause of homeowner insurance claims.
Immediate Response:
- Shut off main water supply (usually in basement or garage).
- Dry the area to prevent mold (mold can grow in 24–48 hours).
- Temporary fix: Wrap the leak with epoxy pipe repair tape or use a pipe clamp with rubber gasket.
Permanent Fix:
- Copper pipes: Solder joint (requires torch—hire a pro).
- PVC pipes: Cut out damaged section, replace with coupling + primer/glue.
- PEX pipes: Use crimp rings and specialized tool (not DIY-friendly).
💡 Prevention Tip: Insulate exposed pipes in winter to avoid freezing and bursting—a frozen pipe can burst with over 40,000 PSI of pressure.
FAQ: Your Plumbing Questions, Answered
Q1: Can I fix a clogged drain without calling a plumber?
A: Yes—for most minor clogs. Try the baking soda/vinegar method or a hand auger first. Avoid chemicals. If water doesn’t drain after two attempts, call a professional to avoid pipe damage.
Q2: How often should I check for plumbing leaks?
A: Perform a monthly visual inspection under sinks and around toilets. Conduct a quarterly water meter test: turn off all water, note the meter, wait 2 hours—any change indicates a hidden leak.
Q3: Is a dripping faucet an emergency?
A: Not immediately—but don’t ignore it. Over time, it wastes water, increases bills, and can cause mold or structural damage. Fix it within 1–2 weeks.
Q4: Why does my toilet gurgle when I shower?
A: This signals a blocked vent stack or main sewer line. The gurgle is air being sucked through the toilet trap due to negative pressure. This requires a plumber—often a sewer snake or camera inspection.
Q5: Can low water pressure damage appliances?
A: Yes. Dishwashers and washing machines may malfunction or wear out faster. Consistently low pressure (<40 PSI) should be evaluated by a licensed plumber.
Q6: How do I know if my pipes are corroded?
A: Signs include discolored water (brown/red = rust), frequent leaks, reduced water pressure, and metallic taste. Homes built before 1970 with galvanized steel pipes are high-risk—consider repiping with PEX or copper.
