Cudahy is small, dense and built on the long narrow lots the area is known for, with buildings often set well back and additions stretching down the property.
That layout means a lot of plumbing runs a long way from the street, frequently added to over time. Long runs of old pipe in the ground are where the failures are.
What goes wrong in Cudahy homes
Main supply line failures between the meter and the house are more common here than the housing type would suggest, simply because those runs are long and old.
The sign is usually a soggy patch in the yard that does not dry, or a water bill that has climbed without any change in use. Neither looks like an emergency until the ground gives way.
The yard is wet in one spot and it has not rained.
That is a supply line under the ground until proven otherwise. Shut the main and see whether the meter still turns; if it does, the leak is between the meter and the house.
Does a yard leak damage the house?
It can. Water saturating soil against a foundation causes movement, and it finds its way under a slab. It is not something to leave until convenient.
