PLUMBING NOTES
Fresh Water Connections
• 1/2" (12.7 mm) NPT – used on syphon breaker, solenoid and
flow control valve.
• 1/2" (12.7 mm) NOM compression – used on sink bowl nozzles.
• 1/2" (12.7 mm) Ridged Copper (compression) – used on hot
water connection to pulper.
• If fresh water supply is greater than 50 psi (144.7 kPa), a
pressure regulating valve must be installed in both.
• It is recommend that ball type shutoff valves be installed
in the cold and hot water lines.
• It is recommended that the hot water connected between
solenoid valve and pulper be terminated with a union for
ease of serviceability.
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
Magnet
• Can be mounted to trough either by tack welding to using weld
studs (see instruction sheet for weld stud pattern).
• Trough magnets should be placed within 12" (304.8 mm) of
end of trough or trough intersection with sink bowl (see Figure 4).
• Additional magnets can be used as necessary.
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.
