Leak Detection Guide: the Tri-Lakes Area

Overview

Not every leak announces itself with a puddle. Water can escape slowly inside a wall, under a slab, beneath flooring or underground between the meter and the house for weeks before anyone notices. Signs include a water bill that has risen without explanation, the sound of running water when nothing is on, warm spots on a floor, musty odors, stains, peeling paint or a water meter that keeps moving with all fixtures off.

Leak detection is the process of locating that hidden water as precisely as possible so that the repair disturbs as little of the home as possible. Plumbers who specialize in it may use acoustic listening equipment, thermal imaging cameras, moisture meters, pressure testing on isolated lines, and tracer gas in some situations. Each has strengths; for example, thermal imaging is useful for hot water lines, while pressure testing helps confirm which branch of the system is leaking.

A simple check you can do yourself is to turn off every fixture and appliance that uses water, then watch the water meter. If the meter's low-flow indicator moves, water is going somewhere. That does not tell you where, but it is useful information to share when you request help.

How it typically works

Confirming the leak exists, often by checking the meter and isolating hot and cold sides of the system.
Gathering information about symptoms, recent bills and any visible damage.
Narrowing the location using pressure tests, acoustic equipment, thermal imaging or moisture readings.
Providing a written summary of findings, which can help with insurance or a separate repair contractor.
Marking the suspected location so repair can be targeted.
Explaining repair options, which might include a spot repair, rerouting a line or, in some cases, repiping.

Before you decide

Slab leaks are more involved. If a leak is under a concrete slab, options may include opening the slab or rerouting the line through walls or the attic.
Detection and repair may be separate services. Some providers specialize in locating leaks and hand off the repair; others do both.
Irrigation systems, pools and outdoor lines can also leak and affect your bill. Mention them if you have them.
Moisture can cause mold. If a leak has been ongoing, ask whether remediation or drying may be needed.
Accuracy has limits. Detection narrows the location, but some uncertainty remains until the area is opened.
Water utilities sometimes offer leak adjustment programs for bills after a repair. Check with your provider.

Local notes for the Tri-Lakes Area

Colorado's Front Range sees sharp temperature swings in winter, and hard freezes can follow mild days. Pipes in exterior walls, garages and crawl spaces are the most exposed, and outdoor hose bibs that are not freeze-resistant or disconnected from hoses are a common trouble spot.

Water in much of Colorado is moderately hard to hard depending on the source, which can contribute to scale in water heaters and fixtures over time. Your local water utility publishes water quality reports if you want specifics.

We take inquiries from Monument, Palmer Lake, Woodmoor, Gleneagle, Colorado Springs.

What to have ready

Find your main water shut-off before you need it, and mention in your inquiry whether you have already shut the water off.
List the times you can be reached and whether someone will be home to provide access.
If you have had related work done recently, note the date and what was done.
Note where the problem is, when it started and whether it is getting worse. A quick photo of the area, any visible leak, and the water heater or fixture label can save time.
Tell us if the issue is affecting your only bathroom or your only source of hot water, which changes how urgent it is.

Signs to slow down

Requests for large cash payments up front before any work or materials are scheduled.
No clear answer about warranties on parts and labor.
No written estimate, or an estimate that does not describe the work, materials and who pulls any required permit.
Prices that change significantly after arrival without a clear explanation of what was discovered.
Recommending that permits be skipped for work your jurisdiction normally requires a permit for.

Questions to ask a provider

Is detection priced separately from repair?
Will I receive a written report of what you found?
If it's a slab leak, what are my repair options?
How soon could repairs start after the leak is located?
How precise do you expect to be before opening a wall or floor?
Do you also check outdoor and irrigation lines?
What detection methods will you use, and why?

Quick answers

Can a leak be found without tearing up my house?: Modern detection tools can usually narrow a leak to a small area, which limits how much needs to be opened. Some access is often still required for the repair.
How do I know if I have a hidden leak?: Unexplained increases in your water bill, a meter that moves when no water is in use, running water sounds, warm floor spots and stains are common clues.
What is a slab leak?: A slab leak is a leak in a water line that runs beneath a concrete foundation slab. It can be detected with specialized equipment and repaired by opening the slab or rerouting the line.
