What Seminole's numbers say about plumbing
Seminole counts 18,997 residents (2025 estimate), growing at a middle-of-the-pack -2.2% since 2020[2]. On the map that's 5.2 square miles holding 3,662 residents per square mile, the 5th densest of the suburbs here; it sits entirely in Pinellas County, with ZIP codes 33772, 33777, 33778[3].
With 10% of homes built since 2010 and 54% before 1980[1], Seminole's plumbing runs from brand-new supply lines and fixtures to aging pipe, original valves and water heaters past their rated life.
Seminole is split across 3 ZIP codes: 33772 (48% of the city's land), 33777 (28% of the city's land), 33778 (11% of the city's land)[6].
Nearest of the other suburbs we track: Largo (4.6 mi N), Pinellas Park (4.8 mi E) and Gulfport (8.1 mi SE)[3].
54% of Seminole's 10,843 housing units predate 1980 and 10% went up in 2010 or later[1] — the 6th-highest pre-1980 share of the 14 Tampa Bay–area suburbs we cover; nearby, Largo (56%), Pinellas Park (57%), and Gulfport (80%) predate 1980. New-construction problems are usually fittings, supply lines, water-heater installs and drain slopes, not worn-out pipe.
The biggest single slice — 28% — was built 1970 to 1979, and the median home dates to 1979[1]. Neighbours from the same era tend to hit the same plumbing problems at the same time.
Water from the sky is plumbing work too: 8 flood or flash-flood reports within 10 miles over 2016–2025[4], and FEMA logged 685 flood-insurance claims across Seminole's ZIPs[5]. Homes that take water need working drainage, sump pumps and backflow prevention.
4% of homes heat with utility gas, and 27% of households rent[1].
Among the 14 suburbs tracked here, Seminole stands out for the 2nd-most flood reports nearby (8, tied with Pinellas Park)[4] and the 3rd-highest gas-heat share (4%)[1].
