Signs to Call for Water Leak Detection and Repair

Water leaks are a danger lurking within the home’s plumbing system, potentially causing severe damage and draining a homeowner’s wallet. Ignoring even a small leak can lead to problems, from high water bills to extensive property damage and mold growth. So, it’s important to call for water leak detection and repair at the first sign of a leak. This post shares some simple ways for people to help catch water leaks in their homes.

High Water Bills

When a water bill is higher than normal without a clear explanation, such as guests staying over so more water is used, or more water was needed for new landscaping, it serves as a clear, urgent indicator that a water leak is present within the plumbing system and that a plumber should be called to locate and repair the leak.

Failing to address a water leak means continuously incurring unnecessarily high water costs and exposing the home to the serious risk of water damage, which can lead to expensive structural repairs and mold growth. Professionals can accurately locate and repair the leak to lower water bills and prevent further damage.

More Signs of a Leak

leak Beyond an unexplained increase in water bills, several other signs can indicate a water leak. A noticeable drop in water pressure from plumbing fixtures, such as showerheads and faucets, can signal that water is escaping the system elsewhere through a leak. Homeowners should also listen carefully for dripping or running water sounds when all appliances and fixtures that use water are off, as this can signal an active, continuous leak.

The presence of mold or a persistent, musty odor is also a common red flag for a water leak. Any evidence of water damage can also indicate a leak, such as water stains and discoloration, peeling or bubbling paint and wallpaper, damaged flooring, or soft spots in walls, floors, or ceilings.

Use the Water Meter

Homeowners can check for a water leak by utilizing the water meter. Start by ensuring that all water sources inside and outside the house are shut off, including plumbing fixtures, appliances that use water, such as dishwashers and washing machines, and outdoor systems, such as sprinklers.

Once nothing inside or outside the home is using water, find the water meter and note the initial reading. Avoid using any water for a set period, typically 1 to 2 hours, and then check the meter again. An increased reading confirms that water is escaping the system somewhere through a leak. Another quick method is to look for the leak indicator on the meter, which is often a small spinning dial, triangle, or star-shaped wheel. If this indicator is moving and spinning without any water being used, it also points to a leak.
