Cottage water realities
Intermittent use, storage tanks, surface influence and guests raise bacteria and sediment risk. Systems should be serviceable by a local tech who understands seasonal properties.
Common cottage stack
- Sediment filtration
- Carbon if taste/odour or some organics
- UV disinfection (with clear water)
- Optional under-sink RO for drinking
- Softener only if hardness and year-round use justify it
Winter tips
Drain lines and filters as needed, follow UV bypass guidance, and re-test after spring opening.
