Case Study: -24°F Frozen Well Switch & Navien E016 Overheat Repair in Wasilla (99623)
The Emergency Situation (Knik-Goose Bay (KGB) / Settlers Bay, Wasilla)
An unsealed foundation vent in the northwest crawlspace corner allowed -24°F wind to freeze both the private well pressure switch sensing tube and a hydronic return line feeding the garage unit heater.
✅ Result: Restored both domestic well water and whole-house hydronic heat in one visit without needing a separate well contractor and HVAC company.
How Our "One-Call" 3-Phase Recovery Executed the Fix
We isolated the 240V well breaker, thawed the crawlspace well manifold, replaced the corroded 1/4-inch steel sensing nipple with a brass tee and new Square D 40/60 pressure switch, and restored 55 PSI domestic water across the home.
We cleaned the Navien internal heating Y-strainer, thawed the restricted garage zone loop, purged trapped air, and verified smooth circulation across all three heating zones.
We installed commercial self-regulating heat trace cable on the well entry manifold and insulated the foundation rim joist with 2-inch rigid foam board.

Because Anchor Services Alaska cross-trains and licenses our emergency crews in both Alaska hydronic heating systems and domestic well/house plumbing—so Mat-Su homeowners don't have to pay two separate call-out fees.
