Quick attention is important when water is spreading near walls, flooring, electrical equipment or stored belongings.

Phoenix hard water and tank maintenance
Mineral sediment can accumulate in the bottom of a storage tank, contributing to noise and reduced efficiency. Maintenance needs depend on water quality, heater design, age and manufacturer instructions. If a tank is already corroded or leaking from its body, flushing will not repair it; replacement is generally the responsible option.

Frequently asked questions
Water Heater Repair and Replacement FAQs
What should I do if my water heater is leaking?
If safe, shut off the water supply to the heater and the applicable energy source, keep clear of hot water and call for service.
Can a leaking water-heater tank be repaired?
Leaks from a valve or connection may be repairable. A tank leaking through its body is generally not repairable and usually requires replacement.
What size water heater does my home need?
Household size, peak hot-water demand, fixture use, available fuel and installation space should determine capacity.
Should I switch from a tank to a tankless heater?
Tankless equipment can be a good fit, but fuel capacity, venting, electrical requirements, flow demand and installation cost should be evaluated first.
