Frequently asked questions
Do I need a permit to replace a water heater?
Yes. Florida jurisdictions require a plumbing permit for a water heater changeout because the work involves gas or electrical connections, temperature and pressure relief piping, and drainage. Replacing without a permit can cause insurance and resale problems.
Can I replace my own water heater?
A homeowner can pull an owner-builder permit and replace a water heater in a home they own and occupy. Electrical and gas connections must still pass inspection.
How long does a water heater last?
Standard tank units last 8-12 years; tankless units often reach 15-20 years with annual descaling. Florida's hard water shortens tank life in many areas.
