Sewer Line Repair in Jacksonville, FL
In Jacksonville, start by confirming whether the home is on city sewer or a septic tank, because the fix is different. Sewer-connected slab homes from the 1950s to 1970s commonly have cast-iron drains under the concrete that are now corroding through. In septic neighborhoods, slow drains after heavy rain usually point to the drain field.

What is different about sewer line repair in Jacksonville?
For cast iron, the signs are slow drains throughout the house, sewer odor and backups that return soon after cleaning. A camera inspection through a cleanout shows the scaling, cracks and worn-through bottom. Repairs are done by tunneling under the house, by opening the floor or, where the pipe is intact enough, by lining.
For septic, pumping the tank and checking the drain field come before any pipe repair. Parts of Jacksonville are being moved from septic to sewer over time, so ask JEA or the city whether your street is scheduled before investing in a new drain field. Permits for plumbing work are issued by the city's Building Inspection Division.

Sewer Line Repair questions from Jacksonville
My drains are slow after it rains. Is that a clog?
If the home is on septic, more likely the drain field is saturated by high groundwater and cannot absorb water. If you are on sewer and it happens in dry weather too, the house drains or the lateral are the place to look.
How long do cast-iron drains last in Florida?
There is no fixed number, but many under-slab cast-iron systems in Florida show serious corrosion after about 50 years. A camera inspection is the only way to know the condition of yours.
