Key Features of Flexcon Well-Rite WR-140R Pressure Tank
Constructed as a 16-gauge steel pressure tank with a urethane finish to withstand damp environments.
Features CAD-2 diaphragm technology with a 100% butyl rubber diaphragm (bladder) tank upper chamber.
Includes a copolymer polypropylene lower water chamber that is anti-microbial for cleaner water storage.
The patented welded stainless steel water connection includes separate air and water seals to prevent leaks.
Comes as a pre-charged residential pressure tank, ready for quick installation.
The water chamber is independent of the tank walls to prevent diaphragm abrasion.
The copolymer polypropylene lower water chamber helps reduce condensation and protects the diaphragm from abrasion.
Optional Tank Installation Kit (Recommended)
The Flexcon WR-140R pressure tank is available in the following options:

Tank with Stainless Steel Install Kit
Includes the WR-140R tank paired with a 304 stainless steel tank tee assembly for complete well system installation.
This installation kit includes the essential components needed for pressure tank setup and system monitoring.
Each tank install kit includes:
Adjustable pressure switch
75 PSI pressure relief valve
Pressure gauge
Union connection for easier maintenance
Hose bib for draining or system testing
Lead-free stainless steel fittings
Important Compatibility Note
The pressure switch included with the installation kit ships factory pre-set to 30/50 PSI and is fully adjustable.
It can be configured to match other common residential well system pressure settings, such as:

Frequently Asked Questions
Is the pressure switch adjustable, or is it locked at 30/50 PSI?
The pressure switch included with the Tank with Stainless Steel Install Kit option is fully field-adjustable.
It ships with a factory default setting of 30/50 PSI, but it can be adjusted to other common residential pressure ranges to match your well system requirements.
Supported pressure switch settings include:
20/40 PSI
30/50 PSI
40/60 PSI
This flexibility allows the tank installation kit to work with most residential well pump systems without needing to purchase a different pressure switch.
How should I set the tank pre-charge?
The Flexcon Well-Rite WR-140R ships pre-charged to 38 PSI, but the air charge can be adjusted to match your pressure switch settings.
For proper operation, the tank pre-charge should be set to 2 PSI below your pressure switch cut-in pressure.
Examples:
20/40 system → set tank to 18 PSI
30/50 system → set tank to 28 PSI
40/60 system → set tank to 38 PSI
Always check and adjust the air pressure with the system powered off and the tank fully drained before making changes.
How is the pressure switch adjusted?
The pressure switch included with the Tank with Stainless Steel Install Kit can be adjusted directly using the internal adjustment nut inside the switch housing.
Turning the nut clockwise increases both the cut-in and cut-out pressure.
Turning the nut counterclockwise decreases the pressure settings.
Always turn off the power to the pump system before making adjustments and verify the final pressure settings using a pressure gauge.
What is the drawdown of the Well-Rite WR-140R?
The drawdown is 15.0 gallons when operating on a 30/50 PSI switch setting, and 13.0 gallons on a 40/60 PSI setting.
Is this an NSF 61 certified 44-gallon potable water tank?
Yes, the Well-Rite WR-140R is NSF 61 certified, making it safe for use in drinking water systems.
Does this tank come pre-charged?
