Leak Detection & Repair Phoenix AZ – Desert Rain Plumbing

Warning Signs

Signs You Might Have a Hidden Leak

Most hidden leaks are silent for months. By the time a homeowner notices, water has often been sitting inside walls long enough to cause mold, structural damage, and significant repair costs.

Unexplained increase in water bill

If your usage hasn't changed but your bill jumped, water is going somewhere it shouldn't.

Sound of running water with everything off

Turn off every fixture and listen. Running water you can't account for is a leak.

Damp spots on walls, floors, or ceilings

Discoloration, bubbling paint, or soft drywall are signs moisture is coming from inside.

Mold or mildew smell with no visible source

Persistent musty odor without visible mold means it's growing somewhere you can't see yet.

Water meter moving with everything off

If the dial is still moving with all fixtures off, you have an active leak somewhere in the system.

Detection Methods

Finding the Leak Without Tearing Up Your Home

Modern detection equipment lets us locate leaks precisely before opening anything — less damage, faster repair, cleaner result.

Acoustic Detection

Sensitive listening equipment picks up the sound of water escaping under pressure — even through concrete, drywall, and tile. Often pinpoints a leak to within inches.

Best for: Pressurized supply line leaks

Thermal Imaging

Infrared cameras detect temperature differences caused by moisture behind walls and under floors. Water shows up clearly against dry building materials.

Best for: Leaks inside walls and ceilings

Pressure Testing

We isolate sections of your plumbing and test pressure to confirm an active leak and narrow down exactly which line is affected before deploying other equipment.

Best for: Confirming and isolating the leak location

We Don't Open Walls Until We Know Where the Leak Is

Some contractors open walls first and ask questions later. We locate the leak precisely before we touch anything — smaller repair footprint, less damage to your home, faster job overall.
