What to Do Next

Step-by-Step Action Plan

Follow these steps before calling a technician — you may be able to resolve the issue yourself.

1

Inspect Visible Pipes

Start by checking all exposed pipes for signs of leaks such as moisture, corrosion, or water accumulation.

2

Check Water Fixtures

Inspect sinks, toilets, and tubs for leaks around their bases and connections.

3

Monitor Water Meter

Turn off all water sources in the house and check your water meter; if it continues to run, you likely have a leak.

Look for Stains and Mold

Examine walls and ceilings for water stains or mold growth, which can indicate hidden leaks.

Evaluate Caulking and Grout

Inspect the caulking around tubs and sinks for cracks or gaps, and consider re-caulking if necessary.

Always turn off power to the unit at the breaker before inspecting any components. Safety first — even for simple checks.
