Some fountains are designed to run continuously, only to be shut down once or twice a year for system maintenance. Others call for the ability to be turned on and off frequently.
For those fountains where frequent on-off operation is to be performed an underground reservoir is required to contain the water in transit 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.
