Original galvanized supply lines
Homes from North Miami’s 1950s-60s building boom often still run on the original galvanized steel supply line, a material that pinholes from internal corrosion well before it fails outright.

A higher water bill with no visible drip anywhere is the most common reason this call comes in, and finding the actual source, rather than guessing at a wall, is the whole job.
Why would my water bill jump with no leak I can see?
A leak inside a wall, under a slab, or in the line running out to a yard fixture produces no visible water at all until it has been running long enough to surface somewhere, which can be weeks after it starts.
A North Miami property dating to the city’s postwar building boom frequently still runs its original galvanized steel supply lines, and that material corrodes from the inside out, developing a pinhole leak long before a section fails outright.
Acoustic listening equipment and pressure testing can isolate a leak to a specific run of pipe without opening walls or cutting concrete on a hunch, which matters most on a slab home where guessing wrong means unnecessary demolition.
A leak that runs for weeks before detection can also affect a shared meter arrangement in a duplex, so a bill that looks wrong for one unit is sometimes worth checking on both sides of the line.
Signs worth acting on
None of these prove a leak by themselves, but together they are worth a look.
A meaningful, unexplained increase is the single most common trigger for this call.
Worth checking as a possible sign of a hot-side supply pipe leaking somewhere beneath the slab.
Turning off every fixture and watching the meter is a simple first check anyone can do before calling.
A slow leak inside a wall cavity often shows up here well before it shows up anywhere else.
A gradual decline, rather than a sudden one, sometimes points to a slow leak upstream rather than a fixture problem.
Why this is common here
The same housing stock that makes cast iron and galvanized replacement common also makes leaks harder to spot on your own.
Homes from North Miami’s 1950s-60s building boom often still run on the original galvanized steel supply line, a material that pinholes from internal corrosion well before it fails outright.
Homes closer to the canal-side neighborhoods sit on ground that is already damp, which can mask the visible signs of a slab leak that would be obvious on drier ground.
Where one meter serves two units, an unexplained bill increase is worth checking against both sides of the property rather than assuming it is only one unit’s fixtures.
Frequently asked
Acoustic and pressure-based detection narrows the location first; opening anything up happens only once the source is reasonably confirmed.
The same detection approach works on the line running out to irrigation or a detached structure, not just inside the house.
Yes, over time it can affect a slab, flooring or the structure around it, which is why an unexplained bill increase is worth checking rather than watching another month.
Yes, the estimate carries no obligation either way.
