5 Common Plumbing Problems Every LA Homeowner Should Know

Most plumbing emergencies do not happen overnight. They start as small, easy-to-ignore issues that gradually get worse. Know what to look for.

5 Common Plumbing Problems Every LA Homeowner Should Know Plumbing Tips

1. Running Toilets

A running toilet can waste up to 200 gallons of water per day. The most common cause is a worn flapper valve, which costs less than ten dollars to replace.

2. Dripping Faucets

A faucet dripping once per second wastes over 3,000 gallons per year. The fix is usually a worn washer, O-ring, or cartridge.

3. Low Water Pressure

If water pressure has dropped throughout your home, the issue could be a partially closed main valve, mineral buildup, or a hidden leak. In older LA homes with galvanized steel pipes, corrosion buildup is a common culprit.

4. Slab Leaks

Southern California homes are particularly prone to slab leaks because most are built on concrete foundations with copper pipes running underneath. Warning signs include unexplained high water bills, warm spots on the floor, damp carpet, or mold growth.

Pro Tip: If your water meter keeps spinning when every fixture is turned off, you likely have a hidden leak. Call a plumber for leak detection.

5. Sewer Line Backups

Tree root intrusion is the number one cause of sewer line problems in Greater LA. Signs include multiple drains backing up simultaneously, gurgling noises, and sewage odors.
