Plainfield's Plumber for Hidden Leak Detection

When you suspect a hidden leak, Leto Plumbing & Heating, Inc. is who Plainfield, IL homeowners have called since 2002. A hidden leak can waste close to 10,000 gallons a year before you see standing water. We find the source with non-invasive listening devices and pressure testing before any wall opens or floor comes up. Call (815) 609-3150 and we'll get out to you.

Plainfield's homes range from subdivisions off Route 30 to older homes near the historic downtown. The Village's Lake Michigan water runs about 6.3 grains per gallon of hardness, leaving deposits in supply lines and fixture connections (whole-house water filters help). Plainfield's silt loam soil compacts when wet, so an underground line leak can pocket for weeks without surfacing.

What We Find

Three Leak Types That Damage Plainfield Homes

Each one hides differently and needs a different approach to locate.

Slab Leaks

Slab leaks crack floors, feed mold, and undermine the structure. We locate the break before any concrete comes up.

In-Wall Pipe Leaks

A pinhole in old, hard-water-pitted copper can soak drywall for months. Pressure testing and acoustic detection find it without opening half your wall.

Underground Water Line Leaks

Soggy or extra-green patches in the yard or erosion near the foundation point to a line leak. If your water meter spins with every fixture closed, call before it migrates toward the foundation.

Warning Signs Plainfield Homeowners Should Know

The EPA puts household leak waste at close to 10,000 gallons a year, and roughly one in ten homes leaks more than 90 gallons a day. Watch for a jump in your Village of Plainfield water bill, especially in spring when sump demand climbs. If a pressure drop is what you notice first, read our article on low water pressure in Plainfield.

How We Work

Non-Invasive Detection Before Anything Is Opened

Pressure Test and Meter Check

We pressure test the supply lines. A spinning meter with every fixture closed confirms water is leaving somewhere.

Acoustic Detection

Listening devices hear escaping water through concrete and soil. Most of the time we can point to within a few inches.

Clear Findings, Repair Options

We explain what we found and your repair options, with Village of Plainfield inspection timing built into the plan. Ask about financing for pipe repair or water valve replacement.

Leak Detection Connects to Bigger Plumbing Health

Water Heater Connections

A water heater leak at the tank base or supply connection is one of our most common calls.

Sump Pump and Basement Water

Before blaming the sump pump, we confirm no supply-side leak is feeding the moisture.

Outdoor Spigot and Valve Leaks

A frozen, cracked outdoor spigot acts like an in-wall leak. We replace spigots and frost-free valves the same visit.

Frequently asked questions

Does Leto Plumbing serve the older neighborhoods in central Plainfield, not just the newer subdivisions?

Yes. Older homes in the historic core often have original copper or galvanized lines, and years of moderately hard Lake Michigan water speed up pipe wall thinning. Newer subdivision homes fail differently, usually from burial depth or backfill settling in compacted silt loam. Our diagnostic approach adjusts for each.

Does leak detection in Plainfield require a permit from the Village Building Department?

Detection doesn't. The repair might, depending on scope. The Village of Plainfield Building Department handles residential plumbing permits under the 2014 Illinois Plumbing Code with local amendments, and materials must stay exposed at rough-in and under-slab stages for inspection. We build permit timing into the repair plan from the start.

Will the leak detection process damage my floors or walls?

Not before we know exactly where the leak is. Acoustic listening and pressure testing usually pinpoint the source to within a few inches before any surface is touched, so you don't pay to open a wall in the wrong place.
