About Cass Plumbing
Small-city streets, older houses, precise plumbing
Dunedin’s downtown and nearby streets hold cottages and bungalows that predate modern PEX and accessible cleanouts. Tight lots, mature trees, and original galvanized or cast iron are common. A repair here has to respect finished floors and narrow side yards.
Cass Plumbing brings the same Florida certified license used across Tampa Bay — CFC057412 — to Dunedin through the Pinellas dispatch line. We explain whether a symptom is a fixture, a stack, or a lateral before recommending replacement.

Services in Dunedin
Plumbing services Dunedin homeowners actually call about
Dunedin cottages often lack a convenient yard cleanout. Finding access is part of the diagnosis, not an afterthought. These are the services Cass Plumbing already publishes. We do not add gas piping, septic pumping, or storm-drain construction to this page unless a dispatcher confirms that scope for your address.
Drain cleaning
Kitchen, bath, laundry, and main-line clogs, including snaking and hydro-jetting when the pipe can take it.
Service detailsSewer line repair
Camera inspections, root intrusion, offsets, and repair options from spot repair to replacement. Trenchless methods only when the footage supports them.
Service detailsCast iron pipe replacement
Scale, cracks, and repeat backups in older homes. Newer Dunedin subdivisions often have PVC — we verify before recommending replacement.
Service detailsSlab leak detection
Acoustic and pressure diagnosis for concealed supply leaks under slab foundations common across Pinellas County.
Service detailsLeak detection and repair
Hidden wall leaks, yard lines, and meter-confirmed water loss, repaired at the source rather than patched.
Service detailsWater heater repair
Electric and gas tank repairs, replacement, sediment, elements, and thermostats. Tankless is discussed when sizing supports it.
Service detailsWater filtration
Softeners, reverse osmosis, and whole-house filtration after a water test — not as a default add-on.
Service detailsFaucet repair
Kitchen, bath, and hose-bibb repairs and replacements, including supply lines that fail inside the cabinet.
Service detailsRepiping
Copper, PEX, and CPVC supply replacement when corrosion or mixed-material remodels justify it.
Service detailsBackwater valves
Protection from sanitary sewer backup during surcharge. Not a fix for stormwater flooding.
Service detailsCommercial plumbing
Restaurants, offices, retail, condos, and medical offices, including grease interceptors where required.
Service detailsAlso see toilet repair, maintenance plan, video pipe inspection, and all plumbing services.

Local conditions
Plumbing challenges unique to Dunedin
These conditions show up often in Dunedin. They do not describe every property. Utility-owned mains and stormwater systems are not household plumbing.
Pre-1980 supply lines
Galvanized supply in older Dunedin houses narrows from the inside. Whole-house low pressure with a healthy meter often means the pipe, not the utility.
Tree-lined laterals
Oaks along Edgewater and inland residential blocks chase moisture at clay joints. Hydro-jetting clears roots; it does not rebuild a collapsed section.
Downtown mixed use
Restaurants and shops near Main Street need grease-interceptor care and after-hours response that a house call does not cover. Commercial and residential scopes stay separate.
Coastal humidity
Even a few blocks from St. Joseph Sound, humidity keeps cabinets damp after a small supply leak. We dry-check the cabinet, not only the cartridge.
