Water Heater and Softener Leak Detection in San Leandro
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 that have water softeners.

Water Leak Detection Cost Comparison in San Leandro, CA
Water leak detection usually costs $150 to $450 depending on the size of the property. Simple repairs like toilet parts may cost $100 to $300, while service line repairs often run $800 to $3,000. Smart shutoff valves usually cost $500 to $1,500 installed. Stopping even a moderate leak quickly can cover the cost of the test in saved water.
Preventative Leak Detection Audits in San Leandro, CA
Beyond emergency services, FBL Plumbing also offers preventative leak detection audits for homeowners and businesses in San Leandro, CA. This proactive approach involves a careful inspection of your plumbing system to identify potential weak points or very small, developing leaks before they become major problems. Regular audits can help extend the life of your plumbing, save on water bills and avoid unexpected costly repairs, especially in older properties.
Leak Detection for PEX and Copper Pipes in San Leandro
Whether your plumbing system uses modern PEX tubing or traditional copper pipes, FBL Plumbing has the expertise to detect leaks in both materials. PEX, while flexible, can be susceptible 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, ensuring accurate detection regardless of your home's plumbing type.
Main Service Line Leak Detection in San Leandro, CA
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 often recommended.
Slab Leak Detection in San Leandro
Slab leaks are common in homes on shifting soil and moving foundations. These leaks occur in pipes beneath your concrete slab, often signaled by warm spots on the floor, sudden spikes in your water bill or the sound of running water when all fixtures are off. FBL Plumbing uses dedicated acoustic listening devices and thermal imaging cameras to precisely locate these hidden leaks without destructive guesswork. Early detection is essential to preventing major foundation damage.
Commercial Water Leak Detection in San Leandro, CA
Commercial properties in San Leandro face added challenges with larger, more complex plumbing systems. Leaks can disrupt business operations, lead to costly downtime and damage inventory. FBL Plumbing offers dedicated commercial leak detection services, using industrial-grade equipment to locate leaks in large facilities, multi-story buildings and specialized systems. We work quickly to minimize impact on your business, providing rapid diagnosis and repair solutions.

Pinhole Leak Detection in San Leandro, CA
Pinhole leaks, often found in copper or PEX piping, are small but can cause serious 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. Wet winters and long dry summers define the plumbing calendar in Northern California, with drainage problems in the rainy season and outdoor leaks in summer.

Water leak detection in San Leandro typically 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.
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 explain any permit requirements.
FBL Plumbing stands behind our work with full warranties on both our leak detection and subsequent repair services. The specific warranty details will be provided in writing before any work begins, for your peace of mind. We use durable materials and proven techniques for lasting solutions.
Yes, a persistent water leak under your home can cause serious foundation damage. Expansive clay soils are common across Northern California, and seasonal swelling and shrinking can crack slabs and buried sewer laterals. Water saturates the soil, leading to expansion and contraction that can shift or crack your foundation, so slab leaks make early detection crucial.
Yes. Repairs we complete carry a written workmanship warranty, and parts include manufacturer warranties. Smart valves also include their own coverage.
Yes, we can also detect leaks in residential and commercial irrigation systems. These leaks can waste large amounts of water and damage landscaping. Our methods can pinpoint leaks in underground sprinkler lines and valves.
Most standard water leak detection services can be completed within 1 to 3 hours, depending on the leak's complexity and location. More challenging leaks, such as those under a slab or within complex commercial systems, might take longer. Our goal is always to find the leak as quickly and accurately as possible.
Many water providers offer leak adjustments if you show the leak was repaired. Policies vary by provider. We give you a written repair invoice to back up your request.
