Start with the homes. A commuter community built around the ferry. Waterfront along Colvos Passage and Yukon Harbor has 1930s to 1960s cottages, many rebuilt or heavily added onto, plus newer view homes. Inland along Sedgwick and Banner the homes are 1970s to 2000s on acreage. Plumbing ranges from galvanized and cast iron in the cottages to copper and PEX in the newer construction. We reach Southworth in about 15 to 20 minutes east of Port Orchard on Sedgwick Road, State Route 160, and the trucks go out stocked for the jobs this community generates most.
Why main water shutoff valve replacement is a little different in Southworth
The freezes that hit Kitsap County in December 2022 and January 2024 taught a lot of Southworth homeowners where their shutoff was, or was not. Some found gate valves that would not close while water sprayed in the crawlspace. If that was you, or you are not sure it would not be, a valve test and replacement is a short visit.
The ground is the other half of the story. Point Southworth is a high glacial plateau ending in clay cliffs above the water, which is why the elevation listed for the CDP is several hundred feet even though the ferry landing is at sea level. Bluff lots are unstable in wet winters. Harper sits low around a tidal estuary with a high water table. Inland, the ground is rolling till with hardpan a few feet down.

In some parts of Southworth the only shutoff is the curb stop in the meter box, and the utility would rather homeowners not operate it routinely. Installing a proper valve at the house entry gives you a shutoff that is yours to use, and we add a drain on the house side while we are there.

Older Southworth homes often have galvanized steel pipe right up to the main valve, and the valve itself is frequently seized into the steel. We transition from the old pipe to copper or PEX with a dielectric fitting, install the new ball valve on clean material, and leave the entry in better shape than it has been in decades.

Main Water Shutoff Valve Replacement questions from Southworth
Is a permit needed to replace a main valve in Southworth?
Replacing a valve in place is generally treated as a repair. Relocating the entry or changing the service line may require a permit in some Kitsap County jurisdictions, and we handle that when it applies.
How do I know if my Southworth main shutoff still works?
Close it, then open a faucet. If water keeps flowing, or the handle spins freely, or the stem weeps, it has failed. If it is a gate valve more than twenty-five years old, assume it is on borrowed time. We test valves on any visit if you ask.
Can you relocate the shutoff in my Southworth house out of the crawlspace?
Yes. We extend the line and bring the new ball valve up into a closet, laundry area or garage wall where it can be reached quickly. It is a common request in Kitsap County crawlspace homes.
How long will my Southworth home be without water?
Usually an hour or two. We shut the water at the meter or the well, drain the house, swap the valve, and refill in a single visit.
Can I shut off water at the meter myself?
In most of Kitsap and Pierce County, yes, with a meter key or a long screwdriver on the curb stop, and we will walk you through it on the phone in an emergency. Some utilities ask that you not operate it routinely. A working valve at the house is a better answer for everyday use.
