Reading the Pasadena data for plumbing

Pasadena is one of the most established suburbs tracked here — 148,539 people (2025 estimate), down just 2.2% since 2020^[2]. It covers 43.7 square miles (3,400 residents per square mile, the 1st densest), sits entirely in Harris County, in ZIP codes 77505, 77506, 77503, 77502, 77504, 77586, 77058^[3].

With 7% of homes built since 2010 and 57% before 1980^[1], Pasadena's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.

7 ZIP codes cover Pasadena — 77505 (19% of the city's land), 77506 (17% of the city's land), 77503 (14% of the city's land), 77502 (13% of the city's land), 77504 (11% of the city's land), 77586 (7% of the city's land), 77058 (6% of the city's land)^[7].

57% of Pasadena's 53,756 housing units predate 1980 and 7% went up in 2010 or later^[1] — the 2nd-highest pre-1980 share of the 15 Houston-area suburbs we cover; nearby, La Porte (42%), Friendswood (30%), and League City (14%) predate 1980. Houses that old can still have galvanized supply pipe or cast-iron drains — especially the 23% built before 1960.

The biggest single slice — 20% — was built 1970 to 1979, and the median home dates to 1977^[1]. Neighbours from the same era tend to hit the same plumbing problems at the same time.
