Water Filters for Condos: Installation Questions

Why condos are different

In a single-family home, a whole-house system goes on the main line where water enters. In a condo building, that main line serves everyone and is usually a common element. Your unit may have its own shutoff and branch lines, but changes to anything shared typically need the association's permission. The CDC notes that people in condos and apartments may not receive the utility's water quality report directly; you can look it up online or ask your building manager.

Options that usually fit a condo

• Under-sink reverse osmosis with a dedicated faucet. It treats drinking and cooking water and stays inside your cabinet. See Living Water's alkaline RO system.
• Under-sink carbon filters for taste and odor.
• Shower filters for comfort, where allowed.
• Unit-level point-of-entry filters are sometimes possible if your unit has an accessible supply line, space and a drain. This always needs approval.

Questions to ask your association

1. Does installing an under-sink filter or RO system need approval?
2. Are there approved contractors or insurance requirements for anyone working in the unit?
3. Are there rules about drilling the countertop for a new faucet?
4. Is the drain line I would connect to unit-owned or shared?
5. Are there scheduled water shutoffs I should plan around?
6. Who supplies the building's water, and where is the latest water quality report?

Questions to ask the installer

• Will the system fit my cabinet with the garbage disposal and other items?
• Where will the drain saddle connect?
• Do you carry the insurance my building requires?
• How do you protect against leaks, and what happens if one occurs?
• Is the system certified for the claims I care about? See reading a certification listing.

Leaks matter more upstairs

A slow drip in a condo can reach the unit below. Ask about leak-detection options, check under the sink after installation and after every filter change, and keep the manufacturer's maintenance schedule. Good installation and regular checks protect you and your neighbors.

Renting the condo out?

If you rent your unit to tenants or guests, the equipment becomes part of what you maintain. Leave the manual and filter schedule in the unit, label the bypass valve, and decide who changes cartridges and when. Florida's Division of Hotels and Restaurants licenses vacation rental condos as public lodging, so short-term rental owners have extra rules to follow beyond the association's. See water treatment for short-term rentals for a maintenance plan that works between guests.

Start with the water you have

Building water can taste different from the street supply because of the building's own pipes and storage. A test at your tap shows what you are actually drinking. Jorge does free in-home tests in condos and apartments and recommends only what fits your unit and your building's rules.
