Municipality of Anchorage (MOA) Boiler, Furnace & Water Heater Permit & Code Guide
Every week in Anchorage and Eagle River, residential real estate closings are delayed because a home inspector flags an unpermitted water heater or boiler missing seismic straps, a thermal expansion tank, a backflow preventer, or proper flue clearances. Anchor Services Alaska resolves home-inspection mechanical and plumbing punch lists in 24–48 hours and performs 100% code-compliant installations.
How Anchor Services Alaska Helps You
MOA Seismic Strapping Code (Post-2018 Earthquake)
Water heaters in Anchorage and Eagle River must be secured in the upper one-third and lower one-third with approved seismic strapping lagged into structural framing.
Thermal Expansion Tanks & T&P Discharge Piping
Closed domestic systems require a supported, pre-charged thermal expansion tank and a full-size 3/4-inch metal/approved T&P discharge tube terminating 6 inches above the floor or drain pan.
Hydronic Boiler Backflow & Low-Water Cutoffs (LWCO)
Boilers require a dual-check atmospheric backflow preventer (Watts 9D) on the domestic makeup water feed to protect drinking water from boiler water/glycol, plus an electronic LWCO.
