1,500+ Reviews 1,500+ Reviews Experience unrivaled water quality with the Sentry G140 Open-Air System, a synergy of aeration and chlorination for superior results. It effectively treats iron (and iron bacteria), manganese, hydrogen sulfide (rotten-egg odor), arsenic, and even methane gas. Pre-wired with a chlorinator, by-pass, bladder tank, and pump for effortless installation.
Two large Open-Air tanks provide ample contact time for oxidation and disinfection, plus bonus storage capacity for low-yield wells.
Three floats, mechanical safety overflow, low-level shutdown, and a water-level-maintaining float, engineered for reliability you can trust.
Complete system with chlorinator, by-pass, bladder tank, and pump, all pre-wired for effortless installation. No scavenging for parts.
As water enters the first 140-gallon chamber, an adjustable venturi adds crucial air, initiating oxidation and diluting gases like methane.
While the tank fills, a chlorinator dispenses precise amounts of chlorine, sanitizing the water and completing the oxidation of odors and bacteria.
A submersible pump in the second 140-gallon chamber repressurizes the treated water, maintaining household pressure in the 40/60 PSI range.
Clean, fresh-tasting, pressurized water is delivered throughout your home, capable of high-flow delivery up to 25 GPM.
For those let down by their original iron filter. The G140 is purpose-built for the challenging Northern Nevada wells that defeat conventional systems.
Users frequently cite "peace of mind" as the biggest benefit, no more orange stains in sinks and laundry, no more rotten-egg showers.
Up to 25 GPM of treated water, plus 280 gallons of buffer storage that doubles as a cushion for low-yield wells.
Requires only regular chlorine pellet top-ups, far easier than manual chemical feeders with tanks, pumps, and metering valves.
Pre-wired and turnkey, our licensed, insured technicians handle the complete installation, typically in a single visit.
Customers report clear, fresh-tasting water that's safe for drinking and extends the life of appliances by removing the minerals that destroy them.
