Fort Lauderdale install conditions
- Beach and downtown towers: building work hours, elevator reservations and tight cabinets add time.
- Older homes: houses in established neighborhoods may have older shut-off valves or drain lines that need attention before an RO system goes in.
- Stone countertops: drilling a faucet hole takes the right tools.
- Offices and short-term rentals: heavier use can call for more production or storage.
How your water affects running costs
The city's 2025 Water Quality Report lists chloramines at an average of 2.3 parts per million. The carbon stages ahead of the membrane take care of that, and how fast they wear depends on your use. The city's water is also softened at the plant, which is easier on membranes than untreated well water. In September 2026 the city began bringing its new Prospect Lake Clean Water Center online, a nanofiltration and ion-exchange plant designed to improve clarity and taste. A test at your tap is the best basis for a filter schedule.
