How to Detect Moisture Under Your House

Moisture beneath your house can lead to serious damage to the structure and foundation. It can also create a breeding ground for mold and mildew, which can pose health risks.

Inspecting the cistern for leaks is a crucial step in safeguarding your home from these issues. Here’s a comprehensive guide to help you identify and address any leaks in your cistern:

Signs of a Leaking Cistern

• Visible Leaks: Check the exterior and interior of the cistern for any visible cracks, holes, or gaps.
• Dampness or Efflorescence: Look for damp or discolored areas on the cistern walls or surrounding soil, which may indicate a leak.
• Reduced Water Level: Monitor the water level in the cistern over time. A significant decrease may suggest a leak.
• Unusual Sounds: Listen for any dripping or rushing sounds coming from the cistern, especially during or after heavy rainfall.
• Mold or Mildew Growth: The presence of mold or mildew on or near the cistern could indicate moisture accumulation due to a leak.

Steps to Check for Leaks

• Inspect the Roof: Check the roof of the cistern for any cracks, holes, or missing tiles that could allow water to seep in.
• Examine the Walls and Joints: Inspect the cistern walls and joints for any visible defects, cracks, or gaps that could be leaking points.
• Check the Inlet and Outlet Pipes: Examine the inlet and outlet pipes for any leaks, loose connections, or corrosion.
• Fill the Cistern and Monitor: Fill the cistern to the top and observe it over several hours. Check for any drops in water level or visible leaks.
• Listen for Leaks: Place your ear close to the cistern and listen for any dripping or rushing sounds, especially during water flow.
• Use a Flashlight: Inspect the inside of the cistern with a flashlight to detect any hidden cracks or leaks.

Repairing Leaks

If you identify any leaks, it’s essential to repair them promptly to prevent further damage. The type of repair required will depend on the nature of the leak.

For small cracks or holes, you can apply a sealant or patch. For larger leaks or structural damage, it’s recommended to seek professional assistance from a qualified plumber or contractor.
