Plumbing systems are essential to the comfort and functionality of every home, yet many homeowners don’t realize there’s a problem until it’s too late. From minor annoyances to major headaches, plumbing issues can quickly escalate into costly repairs if not addressed early. At Pacific Blue Mechanical, we’ve seen it all. Here are the top 10 most common plumbing problems homeowners face—and how to prevent them.
1. Dripping Faucets
A constantly dripping faucet isn’t just annoying—it can waste hundreds of gallons of water each year. The usual cause is a worn-out washer or O-ring that’s easily replaced. Don’t ignore it—fixing it early saves water and lowers your bill.
2. Clogged Drains
Whether it’s in the kitchen, bathroom, or shower, clogged drains are a frequent nuisance. Hair, grease, soap scum, and debris are often the culprits. Drain cleaning and the use of drain screens can help prevent buildup.
3. Running Toilets
A running toilet can waste up to 200 gallons of water a day. Often caused by a faulty flapper valve, it’s a simple fix—but if ignored, it can lead to significant water bills.
4. Low Water Pressure
Low water pressure makes everyday tasks frustrating. It could be due to pipe corrosion, sediment buildup, or a hidden leak. A professional plumbing inspection can pinpoint the issue quickly.
5. Leaky Pipes
Leaks are one of the most common plumbing issues, especially in older homes with Poly B or galvanized pipes. Leaks can lead to water damage, mold growth, and structural issues. If you notice water stains or damp smells, call a plumber right away.

6. Slow Draining Sinks
If your sink drains slowly, it could be due to partial clogs in the drainpipe. This can eventually lead to a full blockage if not addressed. Routine cleaning can help, but persistent problems may require professional snaking or hydro jetting.
7. Water Heater Issues
No hot water? That’s a clear sign of a failing water heater. Whether it’s sediment buildup, a broken thermostat, or a leaking tank, it’s best to get your water heater serviced annually to avoid unpleasant surprises.
8. Sewer System Backup
A sewer backup is one of the messiest and most dangerous plumbing issues. Common signs include multiple drain clogs, foul odors, and gurgling toilets. Backwater valves and regular inspections are key to prevention.
9. Burst Pipes
Burst pipes are usually the result of freezing temperatures, corrosion, or high water pressure. They can cause extensive water damage in a matter of minutes. Proper pipe insulation and pressure regulation can help prevent this.
10. Noisy Pipes (Water Hammer)
Loud banging or rattling sounds in your pipes are often caused by sudden water flow changes. This is known as “water hammer” and can damage your plumbing system over time. Installing air chambers or water hammer arrestors can eliminate the problem.
