Seasonal plumbing maintenance for Bellevue homes

Pacific Northwest plumbing operates on a four-season cycle that's different from California (no real freeze) and different from the Midwest (no atmospheric rivers). The Bellevue homeowner who wins the seasonal game does October winterizing in late September, runs the cold-snap playbook in November and February freezes, walks the 12-item spring inspection in March, and addresses summer high-pressure issues before the AC season peaks. This section is the seasonal calendar — what to do, when to do it, and what fails when you don't.
