Calgary’s Hot Water Heater Repair Team
You may not need a full replacement of your water tank, sometimes a repair can extend the life of your heater. Knight knows that if an appliance can be fixed homeowners should have the chance to keep the appliance running.
Signs you may need a fix for your water heater:
- water either isn’t as hot as it used to be, or has lost heat entirely
- running out of hot water extremely fast
- odd noises coming from your hot water tank
- leaking water
- water coming out of faucets and taps is discolored
We will assess the hot water tank needing repair, offer our expert opinion on fixes, and correct any issues.


Maintenance Services
Water heaters are one of those machines that we take for granted – until they stop working.
Having maintenance performed every 1 – 2 years will not only dramatically extend the life of your water heater, but it will help it perform much more efficiently as well. It’s easy to add to your fall home maintenance checklist.
Did You Know Water Heaters Lose 30% – 40% Efficiency Over 5 Years Due To Hard Water?
Our technicians will not only check all of the components for proper function, but will treat your tank for calcium buildup that coats parts, interferes with heat transfer, and forces your tank to work harder.
Water Softeners
Having a water softener like Water Hound installed will help keep hard scale build-up from forming. Calgary’s water has lots of magnesium and calcium from the Bow and Elbow Rivers, which can cause your hair and skin to dry out, and your clothes to lose their lustre. Not to mention hot water tanks, pipes, and fixtures to lead a much shorter life than intended. Ask your Knight technician if a water softener system is the right solution for you.
