Running water and sanitary sewer systems are key household advancements that have improved quality of life. However, if a problem occurs with pipes, drain lines, plumbing fixtures, or any water-using appliance, leaks can develop, leading to significant household damage, including rot, mold growth, wall and ceiling discoloration, sagging floors and ceilings, peeling paint, increased water bills, and a decrease in the water pressure.

Use this guide to learn more about common causes of household leaks and how to prevent them.

Signs of a Household Leak

Once a leak starts, it may create a range of problems throughout the home, leading to costly repairs. There are a wide variety of signs that can point to a household leak:

• Inexplicable water bill increase

• Sudden decrease in water pressure when no other fixtures are being used

• The sound of running water, rattling, or hissing when the plumbing fixtures are turned off

• Mold and mildew accumulation

• Peeling or blistering paint or wallpaper

• Warped, stained, or sagging floors and ceilings

Faulty Faucets and Toilets

If they don’t create rot or water damage, leaks can go completely unnoticed if you aren’t paying attention to your water bills. Instead, the water runs directly into the drain, such as when a toilet continues to run or when leaking faucets constantly drip.
