Who supplies water in Signal Hill?
Signal Hill gets its water from the City of Signal Hill's municipal water system (about 3,161 accounts and roughly 50 miles of pipeline), according to the Signal Hill Water Department. The water provider owns and maintains the meter and the pipes on the street side of it. The service line from the meter to the house, and everything inside, belong to the property owner. So when there's a leak, the first question is which side of the meter it's on. A leak at the meter box or in the street goes to the water provider. A leak in the yard, the slab or the walls is a private plumbing repair.

What kind of homes and plumbing does Signal Hill have?
Signal Hill is famous for the 1921 oil discovery on the hill. Housing mixes older bungalows near the base of the hill with condos and newer homes built on former oil land, often on sloped lots. Age shows up in predictable ways: galvanized or early copper supply lines that corrode or develop pinholes, clay or cast-iron sewer laterals that crack or let roots in, and water heaters that are past their expected service life.
