7500 Rev 4 Air Upgrade kit

Description

Upgrade Kit – Convert Your 7500 Rev4 Valve Into an Air-Injection Sulfur Removal Valve

Easily convert your existing 7500 Rev4 control valve into a high-performance air injection system—for eliminating rotten-egg sulphur smell and restoring fresh, clear well water.

If your home is battling a persistent sulfur (rotten-egg) odor in the water, this conversion kit offers a smart, cost-effective solution. Designed specifically for the 7500 Rev4 valve, this upgrade transforms your existing control head into a full air-injection system—adding oxygen into the media bed to oxidize sulfur and deliver improved water quality.

What’s Included:

• Two precision injectors and internal valve parts calibrated for air-draw performance

• 3/8″ tubing connecting the air chamber to the valve, pre-cut for easy installation

• A dedicated air-check valve to maintain the pressurized air pocket above the media

• A heavy-duty 1″ steel check-valve for the main piping, preventing backflow and protecting your system

• All necessary O-rings and hardware to retrofit the valve internally

Why This Upgrade Matters:

When it comes to sulfur odor, the standard valve setup isn’t enough—what you need is a pressurized air pocket and proper injection cycle. This kit adapts your 7500 Rev4 to draw in an air slug during regeneration and keep an oxygen-rich layer in the top of the tank during service—essential for oxidizing hydrogen sulfide and delivering odor-free water.  

Key Advantages:

• Upgrade your system rather than replacing the entire valve assembly — significantly lower cost and less downtime

• Engineered specifically for the 7500 Rev4 platform, for fit and control compatibility

• Improves bathing, laundry, drinking and appliance longevity by eliminating sulfur odor at the source

• Heavy-duty 1″ steel check valve gives added plumbing protection and durability

• Easy retrofit installation means you can upgrade without ripping out your plumbing or starting over

Installation Notes:

• Recommended for homes already equipped with a 7500 Rev4 control valve and suitable tank/media setup

• Follow regeneration programming guidelines: the air-draw (typically 10 minutes) and backwash times should be adjusted based on your water quality.

• Ensure proper piping orientation and install check valves in flow direction; incorrect installation may reduce performance

• After installation, run at least 2-3 full regeneration cycles and monitor drain clarity for optimal media startup.

• Minimum operating pressure: 30 psi; maximum: 90 psi. Protect from freezing or direct sunlight if installed in outdoor setups.

Ideal For:

• Homes on well water experiencing sulfur/hydrogen sulfide odor

• Installers and system owners looking to extend the life of their existing 7500 Rev4 valve

• Anyone looking to upgrade to a professional-grade air-injection system without the full system replacement cost
