Facility Water Maintenance
Practical maintenance guidance for bottle fillers, drinking fountains, and seasonal building reopening in offices, gyms, medical offices, senior facilities, and other Delaware facilities.
Short answer: Identify your building's water source, build a fixture inventory, keep a filter replacement log, and flush the building after any seasonal closure or extended vacancy before resuming normal use.
Who this is for: office managers, facility managers, gym operators, medical-office administrators, and manufactured-home or apartment-community managers in Delaware.

When to contact the utility, a plumber, or a qualified professional
Contact your water supplier for questions about the water arriving at your building. Contact a certified lab for water testing, a plumber for fixture or piping work, and a qualified building-water-management professional for Legionella or other health-risk concerns — this site is not a substitute for that expertise.
