  • Page 8: Sizing Requirements

    Sizing Requirements Water Pressure The water system must have a pump big enough to deliver the recommended backwash rate with a minimum pressure at the inlet of the filter of 30 psi. If the existing system can- not do this, it must be upgraded to do so. Whenever possible, the water system should be adjusted to deliver at least 30 psi for even more satisfactory results.

    Installation Instructions 1. Locate the Air and Media Tank close to a drain where the system will be installed. The surface should be clean and level. 2. Shut off all water at main supply. On a private well system, turn off power to pump and drain pressure tank.
