Common Water Heater Issues in South Lakes
Seismic Damage
Alaska's high seismic activity can knock unstrapped water heaters off their bases, causing gas leaks or flooding. Proper seismic strapping is required by code.
Corrosion from Cold Water
Very cold inlet water increases condensation inside the tank, leading to faster corrosion and sediment buildup, especially in older tanks.
Frozen Pipes
In subarctic winters, uninsulated pipes near the water heater can freeze, causing blockages or bursts. Insulation and proper installation are critical.
