Common Water Heater Issues in Mountlake Terrace
Original 1950s–1960s Homes
Most MLT homes were built as post-war housing. Water heater installations in these homes may need code updates: proper venting, seismic strapping, expansion tanks. When upgrading to tankless, gas line sizing often needs attention. We handle all of it.
Water Heater Age
If your MLT home’s water heater dates to the 1990s or 2000s (common after a previous replacement), it’s now 20–30 years old. That’s 10–20 years past typical lifespan. Replace proactively before it floods your garage.
