6 Common Sources of Water Leaks in Your Home

September 8, 2022

Leaks can cause a significant amount of damage to your home's structure. A buildup of moisture caused by a plumbing leak will also create the ideal conditions for mold and mildew growth and may even attract pests. The best way to protect your home from water leaks is to understand how and where they develop.

6 Common Sources of Water Leaks 

Water leaks may be obvious, or you may not notice until you get a larger than normal water bill. Some of the most common sources of residential water leaks include:

  1. Interior Water Leaks. Pipes are installed under your floors, in the walls, and even in ceilings. Anytime a pipe or connection is compromised, it can create an internal water leak.
  2. Toilets. Toilet water leaks can be in the water supply line, in the flapper, or in the wax ring under the toilet.
  3. Plumbing Fixtures. Dripping faucets shower heads, bathtub fixtures, and utility tub fixtures are among the most common types of water leaks. 
  4. Slab Leaks. Deterioration of the pipes as well as cracks and breaks can cause water and sewage to be released under the slab. 
  5. Exterior Water Leaks. A broken water or sewer line in your yard can cause a large puddle of water to form and not go away.
  6. Water Heater. Faulty water connections, loose gaskets, damage to a drain valve, or corrosion inside the water heater tank can all cause water leaks.

Tips to Prevent Water Leaks

Water leaks can be stressful and damaging to your home. You want to do everything you can to avoid leaks. Here are a few tips to help:


  • Check plumbing connections
  • Replace worn or broken parts
