About Water Coolers

Bottleless Water Coolers for Phoenix & Tucson Offices

Replacing your office's 5-gallon jug delivery service with a bottleless water cooler from Steadfast Plumbing & Water Treatment eliminates the weekly truck visits, the empty-jug storage problem, and the running cost of bottled water that scales with every employee. Our bottleless coolers connect directly to your building's water line, run the supply through multi-stage filtration (sediment, carbon, and reverse osmosis), and dispense cold, hot, or ambient water on demand — limitless capacity for the same flat monthly rate regardless of how much your team drinks.

Steadfast Plumbing & Water Treatment has been installing and servicing bottleless coolers across Phoenix and Tucson commercial buildings since the 1990s. We service everything from small professional offices and dental practices up to multi-floor corporate buildings and warehouses with multiple coolers on a single feed line. Our service plan includes regular filter changes, sanitization, and on-site repair — so when something does go wrong, your team isn't standing in line at a vending machine while you wait for a delivery truck. Most customers report payback in 6–12 months versus their previous jug service, with no further per-bottle cost increases as they grow.
