30-Gallon Electric Low-Boy Water Heater Replacement | Tampa, FL (Oct 2025)

30-Gallon Electric Low-Boy Water Heater Replacement — Tampa, FL (October 2025)

In early October 2025, I was called out to handle a leaking 30-gallon electric low-boy water heater in a residential closet. The tank had begun leaking from the bottom — a telltale sign of internal corrosion. My goal was to perform a safe and efficient water heater replacement while preventing further water damage to the home.

I began by cutting power at the breaker and isolating the cold water line. After draining and disconnecting the old unit, I removed the deteriorated drain pan that had allowed water to damage the flooring. A new galvanized pan and PVC drain system were installed to meet current Florida plumbing code standards.

To restore dependable hot water, I installed a commercial-grade 30-gallon low-boy electric water heater with a 6-year manufacturer warranty. This model fits compact spaces perfectly and provides excellent recovery time for small homes and apartments. I replaced all dielectric fittings, tested the electrical system with a multimeter, and calibrated the thermostat for optimal efficiency.

By using professional-grade materials — from dielectric unions to the PVC pan drain — I ensured long-term reliability and safety. Every job is finished with a thorough inspection, including leak checks, T&P valve testing, and temperature verification.
