The Gateway Cities are classic 1950s tract-home territory along the 605, 91, and 710, where slab-on-grade foundations make slab leaks a signature local problem. Original galvanized supply pipe and cast-iron drains from that era are now 60-plus years old. Imported water in much of the area is hard, so water heaters scale up quickly without regular flushing.

Water hardness
Whittier water comes from the City of Whittier (about 65% of residents), with Suburban Water Systems and San Gabriel Valley Water Company serving other areas. The City of Whittier's report for its city wells (2024 data) lists average hardness of 250 mg/L (about 14.6 grains per gallon), with samples ranging 230–270 mg/L, which the USGS scale rates very hard. Hard water shows up as scale in water heaters, tankless units, and fixtures.
