Sentry G140

The 4-Stage Treatment Process

1

Adjustable Venturi Aeration

As water enters the first 140-gallon chamber, an adjustable venturi adds crucial air, initiating oxidation and diluting gases like methane.

2

Precision Chlorination

While the tank fills, a chlorinator dispenses precise amounts of chlorine, sanitizing the water and completing the oxidation of odors and bacteria.

3

Submersible Repressurization

A submersible pump in the second 140-gallon chamber repressurizes the treated water, maintaining household pressure in the 40/60 PSI range.

4

Pressurized Delivery

Clean, fresh-tasting, pressurized water is delivered throughout your home, capable of high-flow delivery up to 25 GPM.

Why Pure Water Systems for the Sentry G140

πŸ†

Tailored for Tough Wells

For those let down by their original iron filter. The G140 is purpose-built for the challenging Northern Nevada wells that defeat conventional systems.

🏑

Peace of Mind, Guaranteed

Users frequently cite "peace of mind" as the biggest benefit: no more orange stains in sinks and laundry, no more rotten-egg showers.

πŸ’¦

High-Flow Capacity

Up to 25 GPM of treated water, plus 280 gallons of buffer storage that doubles as a cushion for low-yield wells.

βš™οΈ

Set It and Forget It

Requires only regular chlorine pellet top-ups, far easier than manual chemical feeders with tanks, pumps, and metering valves.

Professional Installation

Pre-wired and turnkey: our licensed, insured technicians handle the complete installation, typically in a single visit.
