Bainbridge Island: My Water Bill Doubled and Nothing Changed
A bill that jumps with no change in use almost always means water is leaving the system somewhere. Here's how to find out where.

"Why is my water bill suddenly so high" is a question we hear from Bainbridge Island every month, and the answer here usually involves HDPE under paved parking pads and bluff soils above Eagle Harbor. 360 Leak Finders is across the Agate Pass Bridge from the Kitsap side, and we diagnose high water bill before anything gets dug on shared easements through second growth.
Why this happens in Bainbridge Island
Start with a running toilet. A flapper or fill valve that doesn't seat lets water run silently from tank to bowl. Around Fort Ward and Eagle Harbor the housing dates from mid-century cabins, 1970s acreage and 1990s-to-2010s custom homes, which makes this the likeliest answer to high water bill.
Then irrigation. A cracked mainline, a valve stuck open, or a drip zone that never shuts off can run a meter all night. We've seen it near Eagle Harbor more than once, usually on copper shifted at every joint by clay.
Don't overlook a leak on the buried service line. Galvanized steel from the 1940s, copper from the 60s and 70s, polybutylene from the 80s, brittle early polyethylene: all of it fails eventually, and in Kitsap's till and outwash it can leak for months with no wet spot. On Bainbridge Island properties from mid-century cabins, 1970s acreage and 1990s-to-2010s custom homes it comes up more than you'd think.
