Plumbing in Maltby
Maltby is a census-designated place, not a city: 11,277 people at the 2020 census across about 16.8 square miles of south Snohomish County. It grew up around the Seattle, Lake Shore and Eastern Railway in 1887, and developer Robert Maltby subdivided land here in 1890. Today, water and sewer service depends on the address.
Cross Valley Water District, whose service area includes the Maltby Urban Growth Area, serves about 20,000 people from its own wells plus Everett water; its wells average about 94 mg/L of hardness, moderately hard. District sewer in the Maltby UGA is served through King County, while Snohomish County requires an approved well and septic system to build on rural lots.

Local know-how
What's hard on plumbing in Maltby.
Harder district well water
Cross Valley's own wells average about 94 mg/L of hardness, moderately hard and far harder than Everett water. Over years that can leave scale in tank water heaters and on faucet aerators; flushing the tank helps, and we service or replace heaters that rumble.
Septic beyond the sewer area
Cross Valley's sewer service in Maltby covers only part of the Urban Growth Area, and rural lots need a county-approved septic system. Keep grease and wipes out of the drains; if drains slow down, we clear the line and camera-inspect it.
Polybutylene-era homes
Nearly half of Maltby's homes (45%) were built from 1980 to 1999, when polybutylene supply pipe was often installed (roughly 1978 to 1995). Gray plastic lines at the water heater or under sinks deserve a look; we repipe in PEX or copper.

Who provides water and sewer in Maltby?
It depends on the address. Cross Valley Water District serves the Maltby Urban Growth Area with water from its own wells blended with Everett water, and its sewer there is handled through King County. Rural lots outside district service need a county-approved well and septic system. Your utility bill, or the lack of one, tells you which you have.
Is Maltby's water hard?
Moderately, if you're on Cross Valley Water District. The district's production wells average about 94 mg/L of hardness, which the USGS scale rates moderately hard, and wells supply roughly 61% of its water; the other 39% is soft Everett water. Scale shows up first in water heaters and faucet aerators. Private wells vary, so test yours.
