A hidden leak wastes water 24 hours a day and is one of the most common causes of insurance claims in Central Texas. In Leander's slab-on-grade construction, a small leak under the foundation can raise a floor tile by summer and crack a slab by fall. Crystal Falls Plumbing runs a truck-mounted leak-detection kit — acoustic ground microphones, thermal imaging camera, tracer gas, and static line-pressure testers — so we find leaks with less than a square foot of exposed area.
We locate leaks in supply lines (hot and cold), waste lines, irrigation, pool plumbing, and even the buried yard line between your meter and the house. Once located, we quote both a spot-repair option and a reroute option so you can choose the least invasive fix.
Signs of a Hidden Leak
A leak you can't see is often obvious in your water bill or your floors. Look for these classic symptoms.
- Water bill 25–50% higher than the same month last year
- Warm spot on the floor (slab leak, hot side)
- Wet carpet or baseboard with no visible source
- Mildew smell in a specific room
- Water meter running with all fixtures off
- Green stripe of grass in an otherwise brown yard
- Cracked or lifting floor tile
Our Leak Detection Process
- 1. Isolate the System
We shut off all fixtures and read the meter to confirm active water loss, then isolate hot from cold to narrow the leak side.
- 2. Acoustic Scan
Ground microphones and pipe-contact probes listen for the leak's characteristic sound signature through slab, drywall, or soil.
- 3. Thermal & Tracer Confirmation
Thermal imaging highlights temperature differentials on the surface; for slow leaks or gas lines, we introduce a safe tracer gas and sniff-test.
- 4. Repair Options
You get 2 written options: spot repair at the exact leak point, or reroute around the affected line — with pros/cons for each.
What a Leak Detection Visit Actually Includes
- Symptom review — high water bill, wet spots, warm floors, hissing sound, meter movement with all fixtures off, and any recent renovation or repair history
- Meter isolation test — we shut every fixture and watch the low-flow leak indicator on your City of Leander meter to confirm a live leak
- Electronic acoustic leak detection using ground-mic listening equipment on hard floors, walls, and slab
- Thermal imaging on suspected hot-water slab leaks to visualize temperature differential without cutting
- Isolation testing to separate supply from drain and hot from cold — narrows the search before any wall or slab access
- Written diagnostic report with the suspected location, evidence, and comparison of repair vs. reroute options — flat diagnostic fee credited back if you have us do the repair

Serving Leander & Williamson County
In older Cedar Park, Anderson Mill, and Round Rock subdivisions, the hidden-leak pattern is copper pinholes in slab supply lines — Leander's slightly aggressive water eats copper faster than most other Texas metros. In Travisso, Crystal Falls, and newer builds, we more often find manifold connection leaks under sinks and shower valve failures behind tile. We adapt the diagnostic approach to your home's age and pipe type.
