Toilet and Fixture Leak Detection in Redmond, WA
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 Redmond
The water meter is the first and easiest 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.
Slab Leak Detection in Redmond
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. FHN Plumbing uses specialized acoustic listening devices and thermal imaging cameras to precisely locate these hidden leaks without destructive guesswork. Early detection is key to preventing major foundation damage.
Irrigation Leak Detection in Redmond
Drip and sprinkler systems run underground across yards and often account for hidden water loss. Cracked tubing, broken emitters and stuck valves can waste huge amounts of water. We isolate the irrigation system, test each zone and trace leaking lines. Repairs restore proper watering for your landscape.
Yard and Outdoor Leak Detection in Redmond
Leaks in outdoor plumbing, irrigation systems or main water lines buried in your yard can lead to wasted water and landscaping damage. We use ground-penetrating radar and tracer gas detection to locate buried pipes and identify leaks without major digging. Our approach minimizes disruption to your lawn and garden, protecting your property's appearance. Detecting these outdoor leaks early can also prevent erosion and potential foundation issues caused by saturated soil, a serious concern for homes in Redmond, WA.
Preventative Leak Inspections in Redmond, WA
Beyond emergency detection, FHN Plumbing offers preventative leak inspections to identify potential problems before they become major issues. This service is particularly valuable for older homes in Redmond 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 Washington.
