Maywood is one of the densest small cities in the county and the housing stock is old. Narrow deep lots, buildings close to the line, and a lot of properties that have been added to over the years.
Additions are where we find most of the trouble. Plumbing extended into a converted space, often decades ago, joining old pipe to new in ways that were never meant to last this long.
What goes wrong in Maywood homes
Galvanized supply pipe is still in service in a lot of these properties, and it fails from the inside. Corrosion narrows it, pressure finds the thin spot, and a pinhole inside a wall can run for weeks behind stucco before anything shows.
Where a property has been divided into multiple units, one failure affects several households at once, and working out whose responsibility it is delays the response at exactly the wrong moment.
How do I know if I still have galvanized pipe?
Look at an exposed line at the water heater or under the house. Galvanized is dull gray steel and magnetic; copper is obvious by color. Low pressure that got worse over years is the other symptom.
There is a damp patch on the wall but no visible leak.
That is usually a supply line inside the cavity. Moisture meters and thermal imaging find it without opening the whole wall, which is the point of calling before cutting.
