Hot water problems can come from the heater itself or from the plumbing and controls around it. The right fix depends on unit type, age, symptoms, and how your household uses hot water. Tornado Plumbing & Drains provides hot water tank and tankless water heater installations, repairs, and maintenance across Toronto & the GTA. We help you choose the right capacity and setup, then focus on safe, clean installation details and reliable performance. If you’re dealing with no hot water, leaks, or inconsistent temperature, a diagnosis can quickly clarify whether repair makes sense or replacement is the better long-term value.
