Question 1

How do I find the source of a plumbing leak?

Accepted Answer

Check under all sinks for dripping supply lines or drain connections, look for wet spots in ceilings below bathrooms, and inspect around the toilet base and water heater. For hidden leaks, turn off all water in the home and watch the water meter — if it keeps moving, you have an active leak in the system.

Question 2

What are the signs of a hidden plumbing leak?

Accepted Answer

Signs of hidden plumbing leaks include unexplained increases in your water bill, the sound of running water when nothing is on, warm spots on the floor (a possible slab leak), mold or mildew smell without a visible source, and water stains on ceilings or walls. Slab leaks are common in DFW due to shifting clay soils.
