Water Heater and Softener Leak Detection in Portland
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.

Toilet and Fixture Leak Detection in Portland, ME
Toilets are one of the most common sources of wasted water. A worn flapper or a fill valve that never shuts off can leak quietly around the clock. We use dye tests to find leaking toilets and check faucets, showers and supply lines for drips. These fixes are typically quick and save water right away.
Water Meter Leak Testing in Portland
The water meter is the first and simplest leak test. With every fixture and appliance off, a moving leak indicator means water is escaping somewhere. We read the flow rate to estimate how many gallons are being lost. Then we shut off zones one at a time to see which part of the property is losing water.
Pool Water Leak Detection in Portland, ME
Pools lose a lot of water to evaporation in summer heat, so a leak can hide behind normal loss. We use a bucket test to compare evaporation with actual water loss. Then we pressure test pool plumbing and dye test fittings, lights and skimmers. Finding the leak safeguards the pool and the soil around it.
Advanced Leak Detection Technology in Portland
BKN Plumbing invests in modern leak detection technology to provide the most accurate and non-invasive service possible in Portland. This includes high-resolution thermal cameras for detecting temperature changes caused by hidden moisture, sensitive acoustic sensors that listen for the faint sounds of escaping water, and video pipe inspection cameras for internal pipe diagnostics. These tools allow us to find leaks with minimal disruption to your property.
Preventative Leak Inspections in Portland, ME
Beyond emergency detection, BKN Plumbing offers preventative leak inspections to identify potential problems before they become major issues. This service is especially valuable for older homes in Portland 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 Maine.
Commercial Water Leak Detection in Portland, ME
Commercial properties in Portland face added challenges with larger, more complex plumbing systems. Leaks can disrupt business operations, lead to costly downtime and damage inventory. BKN Plumbing offers specialized 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.

Water Leak Detection Cost Comparison in Portland, ME

Smart shutoff valves usually cost $500 to $1,500 installed. Stopping even a moderate leak quickly can pay for the test in saved water.

Frequently Asked Questions About Water Leak Detection in Portland
The cost of water leak detection in Portland, ME typically ranges from $250 to $750, depending on the complexity and location of the leak. Factors like whether it's a slab leak, a wall leak or an outdoor pipe leak can affect the final price. This initial cost covers the specialized equipment and expertise needed to accurately pinpoint the problem before any repairs begin.
BKN 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 specific warranty details with your repair quote.
Yes. Repairs we complete carry a written workmanship warranty, and parts include manufacturer warranties. Smart valves also include their own coverage.
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 phone.
If you suspect a slab leak, the first step is to call a professional like BKN Plumbing right away. Avoid trying to dig or open up the slab yourself, as this can cause more damage. Turn off your main water supply if the leak is severe, and clear the area for our team.
Irrigation and pool top-offs normally increase summer use. But a big jump compared to last summer often points to a leak, especially in irrigation. We can test to find out.
Common signs include a sudden, unexplained increase in your water bill, the sound of running water when all fixtures are off, visible water stains on walls or ceilings, peeling paint, a musty odor or warm spots on your floor, especially near walls.
Small repairs typically do not require a permit, but service line replacements and repipes often do. Requirements vary by city and county. We take care of any permits needed.
