Water heater replacement, repair & installation

Honest guidance on tank vs. tankless, repair vs. replacement, and what makes sense for your home and budget.

Signs your water heater may need attention

No hot water or significantly reduced hot water
Water that is rust-coloured or has a metallic taste
Rumbling or banging sounds from the tank
Water pooling near the base of the unit
Unit is more than 10 years old and hasn't been serviced
Inconsistent water temperature
Pressure relief valve that has discharged or appears worn

These are indicators that warrant an assessment — not a diagnosis. An on-site inspection will determine the actual condition and appropriate next step.

Water heater maintenance

Regular maintenance extends the life of your water heater and can prevent unexpected failures. The following items are generally recommended — some can be done by a careful homeowner, others are best handled by a plumber.

  • Annual tank flush to remove sediment (a plumber can perform this or advise on how to do it safely)
  • Check the pressure relief valve annually — lift and release briefly to confirm it functions
  • Inspect the anode rod every 2–3 years — replacement extends tank life significantly
  • Keep the area around the unit clear of storage
  • Check connections and fittings for any signs of corrosion
  • Know where your shut-off valve is located
