Leak Detection Spokane
Leak detection Spokane homeowners and businesses trust starts with Lilac City Plumbing — because even a small water leak can cause serious damage if left unchecked. We find hidden leaks quickly using professional equipment and fix them right the first time, saving you from costly repairs down the road.
Common Types of Leaks We Fix
Leaking faucets and fixtures
A dripping faucet seems minor but wastes hundreds of gallons a year and adds up on your water bill fast. Lilac City Plumbing identifies the exact source — whether it's a worn washer, bad seal, or failing fixture — and fixes it the same day so you can stop watching money go down the drain.
Under-sink and cabinet pipe leaks
Under-sink leaks often go unnoticed until you open the cabinet and find water damage or mold already spreading. We inspect all under-sink connections and cabinet pipes early, stopping leaks before they rot your cabinetry or damage your flooring.
Leaking supply lines and shut-off valves
Supply lines and shut-off valves wear out over time and can fail without warning. We provide the leak detection Spokane homeowners deserve — checking every connection for cracking, corrosion, or slow drips and replacing worn parts before a small leak turns into serious water damage.
Slab leaks (pipes leaking under your foundation)
A slab leak happens when pipes running beneath your concrete foundation crack or corrode. Left untreated it can weaken your foundation, spike your water bill, and cause major structural damage. Lilac City Plumbing locates the problem precisely — without unnecessary digging or tearing up your floors.
Leaking water heater connections
Water heater connections loosen over time and can leak slowly for months without being noticed. Our licensed plumbers inspect inlet and outlet connections, pressure relief valves, and supply lines — catching leaks early before they cause rust, flooding, or premature water heater failure.
Outdoor hose bib and irrigation leaks
Outdoor hose bibs and irrigation lines take a beating through Spokane's freeze-thaw cycles and can crack or loosen over time. We locate leaks in spigots, hose connections, and irrigation systems that silently waste water and slowly damage your foundation or yard.
Hidden wall and ceiling leaks
Wall and ceiling leaks are the most dangerous because they stay hidden while mold grows and structures weaken behind the scenes. Our specialists use advanced equipment to find leaks inside walls and ceilings without tearing your home apart — keeping repairs targeted and affordable.
Pipe Joint and Connection Leaks
Every joint and connection in your plumbing system is a potential leak point, especially in older Spokane homes. Over time fittings loosen, seals fail, and corrosion sets in. Lilac City Plumbing inspects your full system, identifies failing joints, and makes lasting repairs that meet current code standards.
