PLUMBING NOTES
Waste Connection
• 2" (50.8 mm) NPT – used between disposer, Waste Xpress
and drain
• When connecting the drain line from the disposer to the
Waste Xpress use a maximum of (4) 90° bends (45° bends
are recommended) with a 1/4" (6.4 mm) drop per foot of run
or as local codes apply.
• Floor sink or drains should be installed per local codes but
kept clear of yet accessible to pulper.
• Trough applications in excess of 10' (3.1 m) and/or systems
plumbed with a cold water supply greater than 7 GPM
(26.5 LPM) must incorporate the second drain outlet from the
pulper and be drained independently to floor sink or drain.
TROUGH APPLICATION NOTES
Construction
• The recommended maximum trough length is 10' (3.1 m).
• A silver saver should be fabricated prior to end of trough to
catch utensils and dishes.
Water Supply
• For trough lengths of 10' (3.1 m) or less place water nozzle at
end of trough.
• For trough lengths greater than 10' (3.1 m) place one
water nozzle at end of trough and one mid stream.
• Do not plumb water to disposer grind chamber.
