Cass Plumbing has served Greater Tampa Bay since 2000 as a Florida Certified Plumbing Contractor. For over 25 years, our licensed technicians have handled everything from a single running toilet to complete whole-home repiping — with the same standard of craftsmanship on every job.
We know Tampa Bay plumbing because we live and work here. From historic Hyde Park bungalows with aging cast iron beneath the slab, to downtown condos and growing Wesley Chapel developments, we understand how this region's soil, water, and weather shape the systems inside your walls.
Our philosophy is simple: diagnose accurately, communicate honestly, and fix it right the first time. Every technician is licensed, insured, and arrives in a fully stocked vehicle so most repairs are completed on the first visit.

Plumbing Challenges Unique to Tampa Bay
Tampa Bay's climate, geology, and housing stock create plumbing conditions you won't find everywhere. Understanding these regional factors is the difference between a repair that lasts and one that fails in a year.
Note: these conditions affect many — but not every — Tampa property. A professional inspection is the only way to know what your home actually needs.
Aging Cast Iron Drain Lines
Many Tampa homes built before the 1980s still have original cast iron drain lines beneath their slabs. Over decades these pipes corrode internally, scale up, and develop cracks that cause recurring slow drains and backups.
Slab Foundations & Concealed Leaks
Most Tampa Bay homes are built on concrete slabs with plumbing embedded beneath. A leak under the slab is invisible until it surfaces as a warm floor, a high water bill, or foundation movement.
High Humidity & Coastal Exposure
Year-round humidity and salt air accelerate corrosion on exposed fittings, supply lines, and outdoor hose bibbs, especially in coastal Pinellas and South Tampa neighborhoods.
Mineral Scale & Hard Water
Tampa Bay water carries dissolved minerals that build up inside water heaters, fixtures, and supply lines, reducing efficiency and shortening appliance life.
Storms, Hurricanes & Heavy Rain
Tropical systems overwhelm municipal sewers and can push wastewater back toward low-lying homes. Backwater valves and cleanouts are essential defenses during hurricane season.
Tree Roots in Sewer Lines
Mature oaks and palms in established neighborhoods like Seminole Heights and Hyde Park send roots searching for moisture inside aging sewer laterals, causing progressive blockages.
