Many water heater issues develop quietly between service visits. Here are the problems our technicians find most often when homeowners haven't had a maintenance check in a while.

🔩

Water Heater Anode Rod Depleted

The anode rod is the component that prevents the steel tank from corroding internally by sacrificing itself over time. Once the rod is fully depleted, the tank lining becomes the next target for corrosion and the water supply often takes on a metallic or sulfur smell. We inspect and replace anode rods during every maintenance visit, catching this issue before it progresses to tank failure.

🔊

Water Heater Heavy Sediment Buildup

Calcium and mineral deposits from the water supply settle and harden on the tank floor over time, creating a layer that insulates the burner and forces longer heating cycles. The result is higher gas consumption, reduced hot water output, and the rumbling or popping sounds homeowners often describe. We flush the sediment out during maintenance before it reaches the point where it can no longer be fully removed.

🌡️

Water Heater Thermostat Running Too Hot or Too Cold

A thermostat that has drifted from its original setting causes the unit to either overheat the water, wasting energy, or under-heat it, leaving homeowners with water that never quite reaches a comfortable temperature. Both conditions increase operating costs and reduce comfort. We check and recalibrate the thermostat during maintenance to confirm the unit is operating within the correct and safe temperature range.

⚠️

Water Heater Pressure Relief Valve Not Seating

The pressure relief valve is a critical safety component that releases excess pressure before it can build to a dangerous level. A valve that does not seal properly after activation allows small amounts of water to drip continuously, while a stuck valve may not open when needed at all. We test every pressure relief valve during maintenance and replace valves that fail to perform correctly.

🔧

Water Heater Gas Connections Corroded or Loose

Gas supply connections at the water heater can develop minor corrosion, loose fittings, or wear at the flex connector over years of thermal cycling. These issues rarely cause an immediate failure but can reduce burner performance and, in more advanced cases, create a slow gas leak. We inspect all gas-side connections during maintenance and flag anything that needs tightening or replacement.

💨

Water Heater Vent Blocked or Separated

Flue pipes and venting connections can separate at joints, accumulate debris, or develop rust that partially restricts exhaust flow. A compromised venting path forces combustion gases to work harder to exit the system and, in serious cases, allows carbon monoxide to enter the living space. We inspect the venting path from the unit to the termination point and address any blockage or separation found.

⏱️

Water Heater Slow to Reheat

A unit that takes significantly longer to reheat than it used to is almost always dealing with sediment insulation on the burner surface, a thermostat running below its original setting, or a gas supply not delivering the rated pressure. Recovery speed is one of the most practical indicators of a water heater's current health. Our maintenance process addresses each of the common causes so the unit can return to its original recovery rate.

📅

Water Heater Not Serviced in Over a Year

A water heater that has gone more than a year without professional service may have anode rod depletion, sediment accumulation, and gas connection wear that compound quietly. The risk of a mid-season breakdown or premature tank failure increases with each season skipped. We assess the full unit condition during a catch-up maintenance visit and address what needs correction.

🔴

Hot Water Smelling or Discolored

A sulfur or metallic smell from hot water taps is usually a sign that the anode rod has depleted and can no longer protect the tank lining. Rust-colored water on the hot side points to a corroding tank interior, which is a more serious condition. We assess both situations and explain clearly whether the unit can be serviced or whether replacement is the more practical path.

Reviews

What Our Customers Say

★★★★★

Fixed the rotten egg smell for good

Our hot water had a sulfur smell for weeks and we had no idea why. The technician from Gas Services Edmonton found our anode rod was completely depleted and replaced it. Smell is completely gone now.

★★★★★

Explained why our hot water was running out faster

We assumed our tank was just getting old but the technician showed us the sediment buildup during the flush. Noticeably more hot water available since the service. Wish we had booked this years ago.

★★★★☆

Thorough visit, drain valve needed replacing

Our old drain valve was corroded and needed replacement during the flush, which added a bit to the cost. The Gas Services Edmonton technician explained everything clearly and the tank runs quietly now.

★★★★★

Honest about our tank being near the end

We called for routine maintenance but the technician found early signs of tank corrosion and was upfront that a repair wouldn't extend its life much. Appreciated the honesty instead of an unnecessary flush.

★★★★★

Quick and professional annual service

This was our second year booking with Gas Services Edmonton and the visit was fast since they already knew our tank's history. Great to have the same technician who remembers our specific unit.

★★★★★

Caught a stuck pressure relief valve

During our routine flush the technician found our pressure relief valve wasn't releasing properly. Glad it was caught during a scheduled visit rather than becoming a bigger safety issue later.
