Pond Filtration, Pump Chamber & Reservoir, All-In-One

The Filtered Pump Vault houses the system filtration, pump, pumping components and reservoir in one compact unit.


Did You Know?

The Patented Filtrific® Filtered Pump Vault features large capacity filter baskets which are specifically designed to capture both small and large particulate debris which continually drop into fountains. The downward motion of the water flow into the baskets act as a "debris compactor" forcing the debris into the bottom of the basket. This compacting action helps to extend the system's maintenance window.

"The Best Designed and Most Dependable System on yhe Market"

"From the perspective of a company that has projects in several continents I cannot afford a call-back. Over the years and true effort with many other styles and brands of in-ground filters I am convinced the "Filtrific" filtering systems in the best design and most dependable system on the market for water features large and small. The filters provide for numerous installation configurations and are built to such high standards that I have no second thoughts of using them on my projects in any climate where dependable filtration is required.

  • External Pond Pumps

    The Filtrific Filtered Pump Vault can also be utilized with an external pond pump. Multiple ports of varying sizes can be used for a suction line to pull from the bottom of the chamber.

  • Housing for Auto-Fill, Pump Shut-Offand Overflow Devices

    Designed to simplify a pond installation while providing full functionality, the Filtered Pump Vault can house a wide variety of system accessories. Electric and mechanical auto-fill devices, pump shut-off devices and a built-in overflow are just a few of the system accessories which are easily housed inside the vault. For a full list of the available in-vault accessories please see


Included in both Oasis 1 and Oasis 2 Pond Kits is a Filtrific Bio-Curtain Bio Filter. Placed on either side of the filter carriage, the BioCurtain™ provides a large surface area for colonizing beneficial bacteria to reduce ammonia toxins from fish waste and fish food. The stainless steel hanger positions on the Filter Tank rim providing easy removal and cleaning of the poly-flow filter media.

UV Filtration

An optional UV Clarifier Vault can be attached to the discharge line on the Filtered Pump Vault. The UV Clarifier can effectively eliminate single-celled algae (pea-green water) in the pond.


Hybri-Pond Reservoir 

Ponds which incorporate a waterfall and stream with on / off functionality (Hybri-Pond) require an underground reservoir to house the waterfall & stream water when the system is turned off.

The Filtrific Filtered Pump Vault includes a built-in reservoir specifically designed to capture the water in transit when the system is turned off. If additional reservoir capacity is required, an unlimited number of reservoir expansion units can be attached to the Filtered Pump Vault.

Did You Know?

Berkey Supply offers systems which are designed for all of the visible water to disappear when turned off. Expansion reservoirs can also be added so that all surface water can disappear underground when the system is turned off. Learn More about Berkey Vanishing Waterfall & Stream Kits

Expansion Reservoir Units

As pictured below, expansion reservoir units can be attached to the Filtrific Filtered Pump Vault to provide additional water storage capacity.


Compact Reservoir

The 40 Gallon Expansion Reservoir units nest with the Filtered Pump Vault to create a compact “string” of water storage.

The expansion reservoir units can be placed under walkways, lawns, between rock outcropping or established plantings.

A 140 gallon expansion reservoir unit is also available for use with the T390F Filtered Pump Vault. See for additional information →


Tough Vaults

The Filtered Pump Vaults and Expansion Reservoirs are constructed of heavy-duty, thick polyethylene which is very resistant to roots, rocks and sharp objects. The reinforced design provides strength under the most demanding construction sites and installation conditions.

Amazing Strength

Filtrific® Expansion Tanks are manufactured to meet the demands of both residential and commercial installations. The reinforced top allows the tanks to accommodate placement under ground cover, lawn, walkways or beside driveways where occasional vehicular traffic might be encountered.
