Water Heater Maintenance and Flushing in Greater Vancouver
We provide professional water heater maintenance and flushing service throughout Greater Vancouver. Our licensed technicians perform a thorough inspection and service on your water heater — gas or electric, tank or tankless. Regular maintenance extends the life of your water heater, maintains energy efficiency, prevents unexpected failures, and ensures safe operation. We provide a detailed written report after every service.
Tank Flushing and Sediment Removal
Sediment builds up at the bottom of your water heater tank over time, especially in areas with hard water. This buildup reduces heating efficiency, causes rumbling and popping noises, and can eventually lead to tank failure. Our flushing service drains the tank completely and flushes out accumulated sediment, restoring efficiency and reducing noise. Annual flushing is recommended to extend the life of your water heater.
Anode Rod Inspection and Replacement
The sacrificial anode rod is a metal rod inside your water heater tank that attracts corrosive elements in the water, protecting the steel tank from rust. Once the anode rod is depleted, the tank itself begins to corrode. We inspect the anode rod during maintenance and recommend replacement every 3 to 5 years. An anode rod replacement is an inexpensive way to add years to your water heater's life.
Temperature and Pressure Relief Valve Test
The T&P relief valve is the most important safety device on your water heater. It prevents the tank from overpressurizing or overheating. We manually test the T&P valve to ensure it opens at the correct pressure and reseats properly. A failed or corroded valve must be replaced immediately to prevent a potential explosion risk.
Burner Assembly Inspection and Cleaning (Gas)
For gas water heaters, the burner assembly is inspected for proper flame pattern and cleaned of soot or debris. We check the burner orifice for blockages, verify the flame colour (should be blue with a yellow tip indicator), and test the pilot light or electronic ignition system. A dirty burner wastes gas and can produce carbon monoxide.
Gas Connection and Leak Check
All gas connections are checked for leaks using electronic gas detectors. We verify the gas shutoff valve operates correctly and that the gas supply line is properly sized and in good condition. Gas leaks are a serious safety hazard and must be addressed immediately.
Venting System Inspection
The flue pipe or vent system is inspected for proper draft, corrosion, blockages, and correct installation. Atmospheric vent models require a properly sized metal flue pipe with adequate draft. Power vent models need the blower and vent pipe inspected. We check the outdoor termination for debris, snow, or obstruction.
Combustion Air Check
Atmospheric vent water heaters draw combustion air from the room. We verify adequate ventilation and combustion air supply per code requirements. Inadequate combustion air can cause backdrafting and carbon monoxide production. For direct vent or sealed combustion models, we check the intake pipe for blockages.
Water Connections and Leak Check
All water connections — inlet, outlet, and any recirculation lines — are inspected for signs of leaks, corrosion, or mineral deposits. Shutoff valves are tested to ensure they fully open and close. Flexible connectors are checked for wear. Any slow leaks or drips are addressed to prevent water damage.
Dip Tube Inspection
The dip tube directs incoming cold water to the bottom of the tank, preventing it from mixing with the hot water at the top. A broken or deteriorated dip tube causes insufficient hot water and poor temperature recovery. We check the dip tube condition during maintenance as part of the hot water delivery system assessment.
Thermostat and Temperature Calibration
The thermostat is tested and calibrated to ensure accurate water temperature. The recommended setting is 120°F (49°C) for most households — hot enough for household use but not so hot as to cause scalding risk. We verify the thermostat accurately maintains the set temperature through a complete heating and standby cycle.
Expansion Tank Inspection
If your water heater is connected to an expansion tank, we check the tank for proper air charge using a pressure gauge. A failed expansion tank can cause T&P relief valve discharge, pipe hammer, and system overpressure. Expansion tanks typically last 5 to 10 years and should be inspected annually.
Seismic Strapping Verification
BC Building Code requires water heaters to be secured with seismic strapping to prevent tipping during an earthquake. We inspect the strapping for proper installation, tightness, and material condition. Loose or corroded strapping is replaced or tightened to meet current code requirements.
Carbon Monoxide and Safety Testing
We test for carbon monoxide in the flue gas and in the area surrounding the water heater using a calibrated combustion analyzer. CO detectors on each floor are strongly recommended. We also verify that the water heater is properly grounded for safety.
Drain Valve Service
The drain valve at the bottom of the tank is exercised to ensure it opens and closes fully. A stuck or corroded drain valve prevents proper flushing and can make emergency draining difficult. We lubricate or replace drain valves that are seized. A ball valve drain upgrade is available for heavily used drain valves.
Electrical Connection Check (Electric)
For electric water heaters, we check the electrical connections at the junction box for tightness, corrosion, and proper wire gauge. The thermostat and upper/lower heating elements are tested for continuity and resistance. A failed heating element is a common cause of no hot water in electric models.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
