Pinhole Leak Detection in Ballwin, MO
Pinhole leaks, often found in copper or PEX piping, are small but can cause significant damage over time, especially behind walls or under floors. We employ non-invasive moisture meters to detect elevated humidity levels and thermal cameras to identify cold spots that indicate water. Our plumbers are adept at tracing these elusive leaks without tearing apart your entire home. Swift action on pinhole leaks prevents extensive drywall damage, mold growth and compromised structural integrity. Water heaters face heavy demand in winter, when incoming water is cold and families use more hot water.

Water Heater and Softener Leak Detection in Ballwin
Water heaters and softeners can leak at fittings, valves and drain lines. A softener stuck in regeneration can send water down the drain continuously, and a dripping relief valve on a water heater wastes water too. We check these units carefully and repair or replace failed parts. That often explains a mystery bill in homes with water softeners.
Emergency Water Leak Detection in Ballwin, MO
Some leaks require immediate attention, particularly those causing significant water damage or posing a threat to your property's stability. FGV Plumbing provides emergency water leak detection services throughout Ballwin, MO, offering fast response to urgent situations. Our goal is to quickly find and contain the leak to prevent further damage and begin the necessary repairs as soon as possible, day or night.
Preventative Leak Inspections in Ballwin, MO
Beyond emergency detection, FGV Plumbing offers preventative leak inspections to identify potential problems before they become major issues. This service is especially valuable for older homes in Ballwin with aging plumbing systems. We conduct thorough checks of visible and accessible pipes, connections and fixtures, looking for early signs of corrosion or wear. A proactive approach to leak detection can save homeowners real money and hassle in the long run, extending the life of your plumbing system in Missouri.
Main Service Line Leak Detection in Ballwin, MO
The line from the meter to your house carries full pressure and can leak underground for a long time. Wet soil, soft spots or oddly green patches of yard may be the only clues. We trace the line, listen for the leak and mark it for a targeted repair. Replacing old galvanized or polybutylene service lines is usually recommended.
Leak Detection for PEX and Copper Pipes in Ballwin
Whether your plumbing system uses modern PEX tubing or traditional copper pipes, FGV Plumbing has the expertise to detect leaks in both materials. PEX, while flexible, can be vulnerable to damage from rodents or improper installation, while copper can corrode over time, especially with hard water. Our tools are effective across many pipe materials, allowing accurate detection regardless of your home's plumbing type.
Smart Leak Detection Device Installation in Ballwin
Smart shutoff valves like Moen Flo and Phyn monitor water flow and can shut off water automatically when they detect a leak. Small sensors placed near water heaters, sinks and washers send alerts to your phone. We install and set up these systems so you get warnings before small leaks become big ones. Some insurers offer discounts for these devices.

Frequently Asked Questions About Water Leak Detection in Ballwin
Water leak detection in Ballwin usually costs $150 to $450, depending on property size and how many systems need testing. Repair costs vary based on what we find. We give you a price before we start.
FGV Plumbing stands behind our work. While leak detection itself is a diagnostic service, any subsequent repairs performed by us come with a warranty on both parts and labor. We will provide detailed warranty details with your repair quote.
For minor water leak repairs that don't involve significant alteration to the plumbing system, a permit is usually not required. However, for extensive pipe replacements, re-piping a section of your home or major slab leak repairs, a plumbing permit from the local building department may be necessary. Our team will advise you on any permit requirements.
Common signs of a hidden water leak include unexplained high water bills, damp spots on walls or floors, the sound of running water when no fixtures are in use, a musty odor or visible mold growth. Also, a sudden drop in water pressure or changes in your water meter reading when no water is being used can indicate a problem.
We install smart shutoff valves such as Moen Flo and Phyn, along with wireless leak sensors. These monitor flow and can shut off water when a leak is detected. You get alerts on your smartphone.
Small repairs usually do not require a permit, but service line replacements and repipes often do. Requirements vary by city and county. We handle any permits needed.
A rising water bill, the sound of running water, damp spots, mildew odors and a constantly running water heater or softener are common signs. Oddly green patches in the yard can indicate an irrigation or service line leak. Call us if you notice any of these.
Yes. Repairs we complete carry a written workmanship warranty, and parts include manufacturer warranties. Smart valves also include their own coverage.
