Leak Detection & Repair in Danville, VA

A plumbing leak does not always begin with water pouring through a ceiling. Many start with a slow drip beneath a sink, moisture behind a wall, or an outside faucet that loses a small amount of water each day. Pro-Flo Plumbing provides leak detection and repair in Danville, VA, for visible and hidden problems involving supply lines, fixtures, toilets, appliances, water heaters, and outdoor plumbing. By finding the source early, homeowners can limit water waste and avoid removing finished materials simply to search for the damaged pipe.

Early Signs of a Plumbing Leak

An unexpected increase in the water bill may be the first indication that water is escaping somewhere in the system. Other warning signs include:

Damp cabinets, walls, or flooring

Musty odors or visible mildew

Peeling paint or bubbling drywall

Reduced water pressure

The sound of water when fixtures are off

A water meter that continues moving

Every drain in the house is slow at the same time

Moisture around a wall hydrant, sillcock, or hose bib can also indicate a worn seal, cracked connection, or freeze-damaged pipe. Hose bibs may leak only while the water is running, allowing moisture to enter the wall without creating an obvious puddle.

The Cost of Waiting

A small leak can damage drywall, flooring, cabinets, insulation, and structural framing. Water trapped inside walls or beneath floors may also create conditions where mold and wood deterioration develop.

Outdoor leaks deserve prompt attention as well. A damaged outside faucet can waste water and allow moisture to reach the foundation, siding, basement, or crawl space. Repairing the plumbing early is usually less disruptive than restoring several areas of the home later.

Tools for Finding Hidden Water

Leak detection may begin with a water-meter test, visual inspection, and pressure testing. Electronic listening equipment can help identify the sound of water escaping from concealed pipes.

Thermal imaging may reveal temperature differences behind walls or beneath flooring, particularly when a hot-water line is leaking. Moisture meters help confirm where water has collected, while line-isolation testing can narrow the issue to a particular branch of the plumbing system.

My brother’s apartment was flooding from a very old and non maintenance water heater. The property manager was not capable of getting a plumber there for an emergency that happened around midnight. Marybeth at Pro-Flo Plumbing was able get someone out there in a timely fashion. I’m grateful that they were able to remove the most of water shut off the water.

Pro Flo plumbing fixed two issues in our home that we had been putting off. The price was fair, our plumbers were outstanding and both jobs were done right.
Pro Flo also has now helped the nonprofit animal shelter my wife and I work with (APS Caswell) twice and did a great job for the shelter as well. When you go with Pro Flow, you can count on knowledgeable professionals explaining everything thoroughly, and getting the job done right for a reasonable price. I know my family are Pro Flo customers for life.

Paid this company for nothing! Told them the issue (disconnected pipe and clogged) the man claimed he climbed under the house and seen no issue then charged me a service fee but he didn’t do anything and I had to call another company out and they had the problem fixed within an hour and a new pipe connected.

Common Household Leak Repairs

Frequently repaired leaks include worn toilet components, loose supply-line connections, dripping faucets, and damaged outdoor fixtures. A leaking sillcock may require a new washer, vacuum breaker, internal stem, or complete fixture replacement.

If freezing has split the pipe behind a wall hydrant, the damaged section must also be replaced. Pro-Flo Plumbing identifies the failed component, completes the repair, and tests the line before restoring normal service.
