3-1 Installing the Sand and Gravel Backwash Filter

Selecting an Installation Site

Place the unit on a suitable and level foundation, preferably a concrete floor or pad and near the pump for best operation. The location you select must also have an open drain to a sewer for backwash, a hookup to city water, and a 110-volt electrical source.

Use a fork lift truck when moving the unit to avoid damage.

Installing the Unit

Be sure that piping to the unit has a bypass circuit. The bypass circuit allows for removal of the unit for servicing without interrupting water service. Always run piping full size at 1½” NPT (approx. 38 mm). Connect the entering water connection of the filter unit to the process supply and the leaving connection to the tank. Use 2” NPT (approx. 51 mm) to hook up city water or process water to the backwash connector piping, as well as to connect back-flush connections to the city waste or sewer.
