FAQs
How long does a hot water tank last?
The lifespan of a hot water tank depends on the unit, water quality, installation, maintenance, and how heavily it is used. As a tank gets older, corrosion, leaks, and performance problems can become more common.
Can a leaking hot water tank be repaired?
It depends on where the leak is coming from. A leaking connection, valve, or other component may be repairable. If the tank itself is corroded or leaking, replacement is often required.
How quickly can you replace a hot water tank?
Timing depends on the type of tank required, availability, and the condition of the existing installation. Caldwell Plumbing will assess your system and explain the replacement process and expected timing.
Do you offer emergency water heater repair?
Yes. We provide emergency water heater repair for urgent hot water tank problems throughout Durham Region.
What should I do if my hot water tank is leaking?
If the tank is actively leaking, shut off its water supply if you can safely access it and call a plumber. Keep belongings away from the water and avoid electrical equipment or outlets in wet areas.
Should I repair or replace an older hot water tank?
It depends on the tank’s age, condition, repair history, and the problem you’re experiencing. A minor issue may still be worth repairing, while corrosion, repeated failures, or a leaking tank may make replacement more practical.
Do you install replacement hot water tanks?
Yes. Caldwell Plumbing provides hot water tank replacement and installation, including removal of the existing unit, installation of the new tank, testing, and cleanup.
