Where the drains end up matters just as much. Septic. There is no public sewer in Union or along the South Shore; the Alderbrook area has its own on-site treatment. Shoreline lots along Highway 106 typically pump effluent uphill across the road to a drainfield. Union is about 50 minutes from Port Orchard, west on Highway 3 to Belfair and then Highway 106 along the South Shore of Hood Canal, which puts it comfortably inside the territory we cover every week.
Why water treatment & filtration systems is a little different in Union
Pump houses and well sheds around Union 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.
Then there is the Puget Sound winter. Union faces north across the canal toward the Olympics and takes the wind that comes down from them. The December 2022 and January 2024 freezes split pipes in shoreline cabins and froze exposed lines on the hillside systems, and winter power outages stop every pump on the shore.
Local conditions that affect water treatment & filtration systems in Union
Ask a Union homeowner what goes wrong with plumbing here and you will usually hear a version of this: Septic effluent pumps and alarms on shoreline lots pumping across the highway
Families in Union with a tankless water heater see the benefit of filtration quickly: less scale on the heat exchanger, longer intervals between descalings, and a cleaner inlet screen. A scale inhibitor or softener ahead of the unit is often the single best thing you can do for its lifespan on moderately hard well water.
Here is a Union detail that changes how we approach the job: Weak pressure at the high end of community water systems
Many Union 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.

Signs Union homeowners call us for water treatment & filtration systems
Worth a call
- Water tastes or smells like chlorine, especially in summer
- White scale on fixtures, shower glass and the inside of the kettle
- A tankless water heater that needs descaling every year
- Blue-green stains on fixtures, a sign of low pH eating copper
- A lab report showing nitrates, arsenic or bacteria in a well

Water Treatment & Filtration Systems questions from Union
Do you service filtration systems you did not install in Union?
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 Union?
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 Union homes.
Do you test the water before recommending a filter in Union?
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 Mason County well calls for it. The system we quote comes from those numbers.
Can you install a filter in my Union 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.
Do I need a water softener or a filter?
It depends on what the test shows. Iron, manganese, sulfur and sediment need filters, not a softener. High hardness that scales a water heater and leaves spots on glass may justify a softener or a salt-free scale inhibitor. Many homes in this area are sold softeners for problems a softener does not solve, which is why we test first.
Honest pricing matters more when the nearest alternative is an hour away. Union customers get the same flat-rate quote, approved on the phone before work starts, that we give in Port Orchard.
