Reliable Water Storage. Simplified.

The Well Reserve is designed as a simpler, lower-cost option for properties with a measured, reasonably stable low-yield well— typically producing around 2 gallons per minute or more—but unable to provide enough instantaneous flow for normal household demand.

It is best suited for situations where the well’s sustainable production is well understood and the owner is comfortable having the collection rate set and reviewed as well conditions change.

For very low, variable, seasonal, or uncertain well production—or for homeowners who want the system to automatically monitor and manage changing well conditions—we generally recommend the Well Harvester.

The biggest difference is how the two systems manage the well. The Well Reserve uses an owner-set collection rate selected from measured well production. If sustainable production changes, that setting may need to be reviewed and adjusted.

The Well Harvester is our more advanced automatic solution. It monitors well operation, manages production-based operation, provides automatic over-pump protection, and adapts its operation as well conditions change.

Both systems can provide stored water and dependable household pressure. For a stable, accurately measured well where simplicity and lower upfront cost are priorities, the Well Reserve can be a good fit. For customers who want greater automation, protection, and less hands-on well management, we recommend the Well Harvester.

The systems also connect to the well differently. The Well Reserve keeps the existing well pressure tank in place, while the Well Harvester replaces the existing pressure tank as part of its automated well-control system.

The well’s sustainable production should first be measured. The incoming collection rate is then set below that measured production so the Well Reserve collects water gradually without intentionally demanding more than the selected sustainable rate.

A well test represents the well’s production at that point in time. Because groundwater levels and sustainable production can change seasonally or over longer periods, the collection setting should be reviewed if the well begins producing less water or operating differently.

If you would rather have the system actively monitor changing well conditions instead of relying on a manually selected collection rate, the Well Harvester is the better fit.

The standard Well Reserve does not automatically measure well production or adjust its collection rate as well conditions change. Proper operation starts with accurately measuring the well and setting collection below its sustainable production.

Optional dry-run protection can be added to help shut down the existing well pump if dry-running conditions are detected. This provides an additional layer of pump protection, but it does not automatically change the owner-set collection rate.

If automatic well monitoring, production-based operation, and automatic protection are priorities, we recommend the Well Harvester.

No. Your existing well pump continues moving water from the well into the Well Reserve at the selected collection rate.

The Well Reserve’s integrated booster pump then draws water from storage and supplies the house with dependable pressure and flow.

Yes. The existing pressure tank that serves your well pump should remain installed with the Well Reserve. It continues to support the normal operation and cycling of the existing well pump as water is supplied to the system.

This is an important installation difference from the Well Harvester. The Well Harvester replaces the existing well pressure tank as part of its automated well-control configuration, while the Well Reserve does not.

The integrated booster pump is designed to provide approximately 60 PSI and up to 20 gallons per minute from the stored water.

Actual performance can vary with plumbing size, elevation, filtration, fittings, pressure settings, household demand, and other installation conditions.

Yes. The standard Well Reserve includes 215 gallons of storage. Each Additional Tank Kit increases the total storage capacity by another 215 gallons.

Additional storage may be useful for larger households, irrigation, higher peak demand, or wells that need more time to rebuild stored water.

Yes. Many Well Reserve installations can be completed by homeowners who are comfortable with plumbing, basic system setup, accurately setting the collection rate, and following the installation instructions.

Professional help may still be appropriate when electrical work, well-pump wiring, code compliance, difficult plumbing, or optional pump-protection equipment is involved.

Filtration should be installed before the Well Reserve so the water entering the storage tank and system components has already passed through the filtration equipment.

This helps prevent sediment and other material from collecting inside the tank or interfering with the inlet controls, plumbing, or booster-pump system.

The specific filtration equipment and installation order should be selected according to the water-quality issue being treated, the required flow rate, and the pressure available from the existing well system.

Yes. The Well Reserve can be connected to a properly sized 120-volt generator to operate the booster pump and pressurize the home using water already stored in the tank.

The generator should provide at least the required operating wattage and enough surge capacity for booster-pump startup. The system uses approximately 1,200 watts while operating and approximately 2,250 watts during startup.

Generator size should also account for any other appliances or equipment connected at the same time.

The home can continue using the water already stored in the tank. Once that reserve is depleted, the well must resume supplying water before the tank can refill.

The Well Reserve stores and pressurizes available water, but it cannot create water or guarantee future well production.

If your well is known to vary significantly, periodically stop producing, or has uncertain sustainable production, the Well Harvester is generally the better choice because it is designed to actively manage changing well conditions.

The system should be installed upright on a stable, level surface in a location protected from freezing and weather.

The standard system is approximately 73 inches high, 26 inches wide, and 36 inches deep. Additional space should be provided for plumbing, electrical access, inspection, and service.

The installation area must also have room for the existing well pressure tank, filtration equipment, and the plumbing connections required between those components and the Well Reserve.

Yes. The Well Reserve includes a three-year limited warranty. Coverage applies to system components according to the warranty terms provided with the purchase.

Epp Well Solutions also provides direct product support for questions about operation, troubleshooting, installation, and replacement components.

We ship Well Reserve systems throughout all 50 United States. Shipping costs depend on the destination and are included in your personalized quote.

In-stock orders generally process within two to three business days. Freight transit commonly takes another four to seven business days, although timing can vary by destination, carrier scheduling, weather, and other unexpected delays.
