How to Hook Up a Dual-Compartment Sink With Disposal

A double kitchen sink facilitates cleanups in a crowded kitchen, and installing a garbage disposal on one of the sinks adds operation and improves kitchen hygiene. You do not require a separate P-trap for every single sink — the two drains cause a common trap, most conveniently located beneath the sink with no disposal. Most disposals have a drain outlet on the side and are simple to adapt to a double-sink waste system. You just screw the drain extension to the side of the appliance using the screws and flange which come with this.

Put the drain assembly in the hole in the base of one of the sinks and the garbage disposal holder in the hole in the base of the other sink until you set the sink in the cupboard. Spread plumber’s putty generously across each hole until you screw to the fittings and tighten them using adjustable pliers.

Place the sink set up and attach it to the cupboard using the clips that come with this. Tighten the clips using a screwdriver.

Install the garbage disposal by mounting it in the holder, after the directions of the manufacturer. Generally, you install the disposal by participating it with the holder and rotating it counterclockwise though a quarter turn to lock it in place.

Connect a tailpiece to the outlet of the drain to the sink with no disposal. The tailpiece is a part of pipe which you tighten onto the threaded drain socket with a compression nut. The nut comes with the drain assembly, but you might have to purchase the tailpiece.

Slide a plastic compression nut on the tailpiece, followed by a compression washer, and connect a tee with its vertical outlet facing the garbage disposal. Tighten the compression nut to hold the elbow to the tailpiece.

Assess the distance between the tee outlet and rubbish disposal sockets and cut a piece of flanged PVC extension pipe to this length with a hacksaw. Slide the rubber disposal washer on the flanged end of this pipe, then slide the mounting bracket to your disposal on the pipe. Follow this with a compression nut and washer for link to the tee.

Feed the pipe into the tee outlet and tighten the compression nut to hold it, then push the flanged end of this pipe into the disposal outlet and secure the mounting bracket using the screws that came with it.

Mount a P-trap meeting to the bottom end of this elbow and tighten the compression nut by hand. Rotate the trap to meet the drain inlet in the wall, which should already be equipped with a P-trap adapter. Secure the trap to the adapter using a compression nut and tighten the nut by hand.
