Leak Detection in Gainesville, FL

Gainesville at a glance

Gainesville, home of the University of Florida, draws its water from the Floridan aquifer, which gives it naturally hard water. Older neighborhoods near campus, rental houses and newer subdivisions all see their share of hidden leaks.

Why leaks happen in Gainesville

• Hard water from the limestone Floridan aquifer (GRU reports about 140 mg/L) that builds scale in pipes and fixtures.
• Karst limestone ground that can settle under slabs.
• Older rental homes near campus with aging plumbing.
• Slab foundations with lines under the floor.
• Pools and irrigation in many single-family homes.

Many Gainesville homes are slab-built, and a large share of houses near the university are rentals where leaks can go unnoticed. A moving meter, warm floor or a sudden high GRU bill are the usual first clues.

Slab leak detection and repair in Gainesville

A slab leak is a broken water line under the concrete foundation. Common signs in Gainesville homes are warm spots on tile, the sound of running water with everything off, a meter that never stops and a water bill that jumps. The line is isolated and pressure-tested, then the leak is pinpointed with acoustic ground microphones and thermal imaging and marked on the floor. The repair is a spot repair through one small opening, or a reroute of the line through the walls or attic. See slab leak repair cost.

Water line leak detection in Gainesville

The buried service line from the meter to the house is the homeowner’s responsibility in most of Gainesville; the utility, Gainesville Regional Utilities (GRU), usually owns the meter and the line up to it. A soggy strip of lawn, low pressure or a meter that moves with the house shutoff closed points to this line. The line is traced, then listened to with a ground microphone, or tested with tracer gas if it’s plastic, and the leak is marked so only one small hole is dug.

Hidden leak detection inside Gainesville walls, ceilings and floors

Stains, bubbling paint, soft drywall, a musty smell or a ceiling leak under a bathroom usually mean a supply line, drain, shower pan or valve is leaking out of sight. Moisture mapping and thermal imaging show where the water is, acoustic listening finds pressurized leaks, and the opening for the repair is small and in the right place.

Pool leak detection in Gainesville

If your pool drops more than a bucket of water set on the step over 24 hours, it’s leaking. Pool leak detection checks the shell, skimmer, returns, main drain, lights and the buried plumbing lines, using pressure testing, dye testing and underwater acoustic equipment. See how to find a pool leak.

How to check for a leak in your Gainesville home

1. Turn off every faucet, the washer, dishwasher, ice maker and irrigation.
2. Watch the leak indicator on your water meter for 15–30 minutes.
3. If it moves, close the main shutoff in the house. If the meter still moves, the leak is in the buried line outside; if it stops, it’s inside or under the slab.
4. Put a few drops of food coloring in each toilet tank. Color in the bowl after 15 minutes means a toilet leak.
5. Still moving? Call (877) 729-0265 to get the leak found.

Leak detection cost in Gainesville

The price depends on the type of leak, how many lines need testing and what’s above the pipe: tile, concrete, landscaping or a pool deck. Detection and repair are quoted separately. Finding the leak first keeps the repair small. See what affects leak detection cost.
