Call (330) 302-2992 A damp patch spreading across the basement ceiling is often the first sign of a supply line leak, and finding the source is usually harder than stopping it. Youngstown’s older housing stock adds a complication: one house can hold original galvanized steel, copper from a remodel, plastic from later repairs and a lead service line at the street. Leaking supply lines are among the work Ewan knows best.
A supply line is under pressure all the time, so a leak runs whether a tap is open or not. The usual signs:
A sudden pressure drop across the whole house can mean a leak on the service line.
Closing valves isolates one section of piping at a time, and the meter or a pressure gauge shows which section keeps losing water; moisture meters, thermal cameras and listening equipment then trace it, so the wall or ceiling is opened once, in the right place.
Yes. Turn off every tap and every appliance that uses water, then watch the water meter: most have a small dial or triangle that turns with even a slight flow. If it moves with everything off, water is going somewhere.
Ice forms where a pipe is coldest, such as an outside wall or the rim joist, and as it grows it pushes water toward a closed faucet. The pressure in that trapped stretch can split the pipe between the ice and the faucet, and the split leaks only once the ice melts, so damage from a lake-effect cold snap often shows when the weather turns. The first steps after a burst are covered under emergency plumbing.
Pressure pipe fails according to what it is made of, so the material usually decides the repair.
| Material | Commonly found in | Typical failure | Usually repaired or replaced |
|---|---|---|---|
| Galvanized steel | Houses built before about 1960, often still feeding a bathroom or kitchen | Rust and scale close the pipe from inside, cutting pressure and staining water; threaded joints leak where the wall is thinnest | Replaced: a leaking joint can be fixed, but the rest of the run is usually as worn |
| Copper (Type M or L) | Houses built or replumbed from the 1950s on; thin-wall Type M indoors, heavier Type L on service lines | Pinhole leaks from corrosion, leaking soldered joints, splits after a freeze | Repaired a section at a time, unless pinholes keep appearing across the house |
| Lead | Service lines from the street into the basement, in many houses built before the 1950s | Lead dissolving into water that sits in the line; leaks at old joints | Replaced, the whole line; a partial replacement can raise lead levels for a time |
| CPVC | Repairs and additions from the 1980s on, and some whole-house runs | Turns brittle with age and heat, then cracks at fittings when bumped | Repaired while the pipe is sound; replaced once it cracks wherever it is touched |
| PEX | Most repiping and new work since about 2000 | Leaks at crimp rings and fittings; damage from sunlight or rodents | Repaired: a fitting or a short section is replaced |
In many older houses galvanized steel meets copper without a dielectric union, and that joint corrodes faster than the pipe on either side.
A spot repair answers a local accident; repiping answers the age of the whole system. Repeated leaks in the same old pipe, or a renovation with the walls already open, usually tip the balance toward repiping.
Two gray metals come into older basements. Galvanized steel is hard, a magnet sticks to it, and a scratch shows dull gray metal. Lead is soft, a magnet does not stick, and a scratch with a key shows bright silver; it usually runs from the street through the foundation wall to the meter, often ending in a rounded, bulb-shaped joint. Galvanized pipe that has sat downstream of lead can hold lead in its scale too.
A lead service line is replaced, not patched, and the work involves the water utility, which keeps a record of service line materials. Until then, use cold water for drinking and cooking, and let it run after it has sat for several hours. The safety and code rules for that work are covered under How We Work.
If water is spreading, close the main shutoff first, then call or book and say where the stain or the sound is.
