Drainage systems

james.parera

Hi All
one of my cline has recently changed his double drain sink with a single drain sink.
I now need to redo all the plumbing to allow for single drain usage.
I am having a hard time trying to find what is the proper way to install the disposal and dishwasher to a single drain,
and at the same time what is the proper layout of the PVC piping.


we will highly appreciate your feed back.
Thanks in advance.

The disposal is obviously installed on the single drain sink. The disposal unit should have a short dishwasher "pipe" for the dw drain hose to slide onto for double-clamping with ring clamps from the air gap (if required by code in your jurisdiction).
Don't forget to knock out the plug with a screwdriver and hammer on the disposal before attaching the dw hose.
The disposal then drains through a trap.
Good luck!
Mike
