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.
