Washington west of the Cascades gets long stretches of sustained rain from Pacific atmospheric rivers, and that steady saturation is behind most of the drain and sewer emergencies in Seattle, Tacoma, and the rest of the Puget Sound region. Older neighborhoods still run clay or cast iron sewer laterals, and the region's big, established trees send roots straight toward those pipe joints looking for moisture, which is one of the most common reasons a sewer camera inspection turns up root intrusion here. East of the mountains around Spokane, the climate runs drier and colder, and winter cold snaps there are sharp enough to ice up exposed pipe that wasn't built with that kind of cold in mind.
Crawl spaces, not basements, are standard under most homes on the west side, and a slow leak down there can go unnoticed for a long stretch since it's not space anyone walks through regularly. It usually turns up as a spike in the water bill or a musty smell before anyone sees actual water. Hard water varies a lot by region here, generally soft around Seattle and harder east of the mountains, which changes how fast scale builds up inside water heaters depending on where in the state a home sits.
- Sewer line root intrusion in older Seattle and Tacoma neighborhoods
- Undetected crawl space leaks in wetter western Washington
- Occasional hard cold snap pipe bursts, especially east of the Cascades
- Storm-driven drain and sump pump backups during heavy rain
