The Pump Vault Dry / Extension supports the successful realisation of projects with water elements in two ways and with minimal installation effort. It serves as a safe place to place pumps in a dry installation. Water runs directly into the pump via a hose connection instead of flushing around it. Or, if required and depending on the individual installation situation, the pump shaft of the Pump Vault 60000 can be raised by removing the base of the extension using a jigsaw, for example, and then placing the housing on top of the chamber. The pump shaft, which can be buried out of sight, provides optimum access to the pump for maintenance and winter storage.
