Simple Steps Before We Arrive
What to Do When Your Hot Water Is Not Working
Losing hot water can quickly disrupt your day, from showers and washing to cleaning and everyday comfort. Follow these simple steps to stay safe, check the obvious issues, and know when to call a professional plumber.
Check Other Taps First
Test hot water from more than one tap in your home. If only one tap is affected, the issue may be with that fixture. If there is no hot water anywhere, the problem may be with the hot water system.
Check the Power, Gas, or Pilot Light
For electric systems, check whether the power supply or switch has tripped. For gas systems, check whether the gas supply is on and whether the pilot light is still lit. Do not attempt to repair gas or electrical components yourself.
Look for Leaks or Warning Signs
Check around the hot water unit for leaking water, rust, unusual noises, error codes, or a strong smell of gas. If you notice a gas smell, turn off the gas supply if safe and contact a licensed professional immediately.
Call a Hot Water Repair Plumber
If the system is leaking, not heating properly, making unusual noises, or repeatedly losing hot water, contact a licensed plumber. We can inspect the unit, diagnose the issue, and recommend the right repair or replacement option.

What types of hot water systems do you service?
We can assist with electric, gas, storage, continuous flow, and common residential hot water systems.
Why do I have no hot water?

Should I repair or replace my hot water system?
If the issue is minor, repair may be suitable. If the system is old, leaking, inefficient, or breaking down often, replacement may be the better option.
