INSTALLATION TYPES

If you have the ability to plumb a complete second discharge piping network for your new backup, this is the best possible installa-
tion, as it offers you an added backup solution in the event the primary pump discharge ever becomes blocked. To accomplish this,
install a 90° street elbow (included) into the 442 (tightening to 15 in-lb) and plumb a second line. Two alternate methods of installing
a 442 into existing primary pump piping are shown below.
Method A: Vertical installation is recommended for compact sump pits and sump pits where the buildup of sediment (rocks, sand,
mud, etc.) is an issue. The 442 comes with all fittings for this installation (included 90° street elbow is not used in this installation).
Method B: Side-by-side Installation, a popular option in larger sump pits when it is desirable to have the backup pump and primary
pump on the same level. This installation will require a tee, a 90° elbow, and two sections of piping. A 90° street elbow is supplied.
