How to Check for Moisture Under My House?

Moisture beneath your house can lead to a slew of issues, including foundation damage, musty odors, and mold growth. One potential source of moisture is a leaking irrigation system. Here’s a step-by-step guide on how to inspect your irrigation system for leaks:

Step 1: Turn Off Water Supply

Before examining the irrigation system, turn off the water supply at the main valve. This will prevent water from flowing through the system and potentially causing more damage.

Step 2: Inspect Visible Components

Check for visible signs of leaks, such as wet soil, pooling water, or broken pipes. Examine the sprinklers, valves, and hoses for any wear or damage.

Step 3: Conduct a Pressure Test

Attach a pressure gauge to a faucet or sprinkler head. Turn on the water supply and observe the pressure reading. If the pressure drops rapidly, it may indicate a leak in the system.

Step 4: Use a Moisture Meter

A moisture meter can detect areas of moisture beneath the soil’s surface. Insert the probe into the ground near the irrigation lines to identify any areas with excessive moisture.

Step 5: Check for Damp Spots

Inspect the basement or crawl space for damp spots or mold growth. Moisture from a leaky irrigation system can seep into the soil and spread throughout the structure.

Step 6: Call a Professional

If you suspect a leak but cannot identify its source, contact a qualified plumber or irrigation technician. They have the expertise and equipment to detect and repair leaks effectively.

Additional Tips

• Regularly inspect your irrigation system, especially after heavy rainfall or freezing temperatures.
• Maintain proper watering schedules to prevent overwatering and potential leaks.
• Install leak detectors in areas where leaks are likely, such as the basement and near sprinklers.
• Consider using drought-tolerant landscaping to reduce water consumption and the risk of leaks.
