Plumbing in Mount Vernon
Skagit PUD's Judy Reservoir system supplies more than 116,000 people, most of them in Mount Vernon, Burlington and Sedro-Woolley. Four Cultus Mountain creeks (Gilligan, Mundt, Salmon and Turner) feed the reservoir, along with water pumped from the Skagit River. The PUD rates the water soft at 21 mg/L of hardness in its 2025 report, adds no fluoride, and raises the pH to a target of 8.8 to control corrosion because the water is naturally soft.
The city's parks plan maps sizable flood-prone areas across most of downtown and the west side, including the lowlands along Kulshan Creek, Carpenter Creek and Britt Slough. Downtown now sits behind a floodwall, completed in 2018, that took 223 buildings out of the floodplain, and it stayed dry in December 2025 when the Skagit crested at a record 37.73 feet. The rest of the valley floor depends on dikes, so flood planning still matters in the lowlands.

Local know-how
What's hard on plumbing in Mount Vernon.
Flood prep in the lowlands
The west side and the Kulshan Creek, Carpenter Creek and Britt Slough lowlands are mapped as flood-prone. Test your sump pump every fall, keep the water heater and furnace raised off the floor, and ask us about a backwater valve on the sewer line.
Outdoor faucets and backflow
Skagit PUD runs a cross-connection control program to keep backflow out of its mains. Don't leave a hose sitting in a bucket or trough, keep the vacuum breaker on each outdoor faucet, and let us replace hose bibbs that leak or lack one.
Water heaters in newer homes
About 32% of Mount Vernon homes were built in 2000 or later, and tank water heaters typically last 8 to 12 years. If yours is original to the house, replace it on your schedule instead of after a leak. We install tank and tankless models.

Good questions
Mount Vernon plumbing FAQ.
Don't see your question? Call or text (425) 845-3535. A real person answers, 24/7.
Is Mount Vernon's water hard?
No. Skagit PUD's 2025 water quality report lists Judy Reservoir water at 21 mg/L of hardness, which is soft on the USGS scale. Because the water is naturally soft, the PUD adds caustic soda to raise the pH to about 8.8, which helps control corrosion in pipes. With water this soft, a water heater's age usually matters more than mineral scale.
Do older Mount Vernon homes still have galvanized pipes?
Some do. Census estimates put about 18% of Mount Vernon homes before 1960, when galvanized steel supply pipe was common. It corrodes from the inside, so low pressure, rust-colored water and leaks at threaded joints are warning signs. We can inspect your lines and give a written, flat-rate price to repipe in PEX or copper.
