Where the water comes from changes the diagnosis. A mix. Some of the Harper and Southworth area falls within Manchester Water District's boundary, while many homes along Sedgwick Road, Banner Road and the back roads are on private wells or small shared systems. 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 water treatment & filtration systems is a little different in Southworth
Older Southworth homes on city water often have their own galvanized service line shedding rust into otherwise clean water. A sediment filter helps, but the real fix is replacing the line, and we tell you that rather than selling a filter to treat a problem the pipe is causing.
Sewer versus septic is the next question. No public sewer serves Southworth or Harper. Everything from the ferry landing to the bluff homes on Point Southworth is on septic, with pumped systems common on the small waterfront lots.
Local conditions that affect water treatment & filtration systems in Southworth
In Southworth specifically, one issue comes up more than most: Water lines crossing unstable bluff slopes that shift and leak
Many Southworth homes rely on private wells drilled into glacial sand and gravel, and that groundwater carries iron, manganese and often hydrogen sulfide. A backwashing iron filter sized to the well's flow ends the orange stains and the smell, and a sediment filter ahead of it keeps grit from a shallow well out of the house.
Ask a Southworth homeowner what goes wrong with plumbing here and you will usually hear a version of this: Crawlspace groundwater and sump pump failures in the low ground at Harper
Pump houses and well sheds around Southworth get cold enough in a hard freeze to split a filter housing, and we replaced several after the December 2022 and January 2024 cold snaps. When we install in an unheated space we insulate every line and talk about a heat source for the building.

Water Treatment & Filtration Systems questions from Southworth
Do you service filtration systems you did not install in Southworth?
Yes. We change cartridges, replace media, repair control heads and, when a system was oversized or wrongly chosen, resize or replace it. We will tell you plainly if what you have is the wrong tool for your water.
Is a whole-house filter enough for drinking water in Southworth?
For taste, smell and clarity, yes. For dissolved contaminants flagged by a lab report, an under-sink reverse osmosis system at the kitchen is the right addition, and we install both together in Southworth homes.
Do you test the water before recommending a filter in Southworth?
Always. We test iron, manganese, hardness, pH and sulfur on site from the raw water and send lab samples for bacteria, nitrates or arsenic when a Kitsap County well calls for it. The system we quote comes from those numbers.
Can you install a filter in my Southworth pump house?
Yes, and we do it often. The system goes after the pressure tank with a bypass and isolation valves, a drain for any backwashing tank, and insulated lines so it survives a freeze.
Will a whole-house filter lower my water pressure?
A properly sized one should not noticeably. The pressure complaints we see come from undersized cartridge housings and clogged cartridges that were never changed. We size to the home's peak flow, use large-port housings, and install a bypass so a clogged filter never leaves you without water.
Greg started this company to do plumbing the way he would want it done at his own house: show up when promised, explain the options, and leave the place clean. That is what Southworth homeowners can expect from us.
