A newly installed microwave not only needs a water supply, however it needs somewhere to drain the water in the tub once it completes the wash cycle. In case you’ve got a garage door attached attached for your double sink, the maker automatically provides a link to your dishwasher drain line, but if you don’t have a garbage disposal, you have to connect the drain line into a double sink drain. Fortunately, you can put in a drain fitting intended for this dilemma as opposed to change your whole drain system under the sink.
Choose the sink drain closest for your dishwasher setup to connect your dishwasher. Turn off the faucet supply lines to avoid a water litter if someone inadvertently turn on the faucet while you’ve got the drain line disconnected, when desired.
Look under your sink to get the bottom of the strainer basket. Find the slip nut that connects the sink’s drain tailpiece into the drain basket. Loosen the slip nut using pump pliers. Allow the slip nut slide down the drain tailpiece.
Pull the tailpiece in the drain basket. It shouldn’t require much force to pull on the tailpiece in the basket.
Start looking for the second slip nut at the bottom of the tailpiece. Loosen this nut, using the pump pliers.
Lift the original tailpiece in the drain line connecting both sink drains. Discard the slip nut which connected the tailpiece into the drain basket. The slip nut which connected the bottom of the tailpiece will stay on the drain.
Measure the length of your original sink drain tailpiece. Move the dimension to your PVC dishwasher wye tailpiece.
Cut the end from the bottom of the new tailpiece, with a hacksaw, if necessary. Sand the edges of the cut, using 320-grit wet/dry sandpaper.
Eliminate the slip joint washer from the slip nut you left connected to the drain line. Insert a fresh, rubber slip joint washer into the slip nut.
Insert the cut end of the PVC dishwasher wye tailspiece into the drain line slip nut. Tighten the nut using the pump pliers.
Combine the top of the dishwasher wye to the bottom of the drain basket. The wye comes with a new slip nut and washer attached to the peak of the wye.
Slide the slip nut and washer up the wye and twist it clockwise to connect it into the drain basket. Tighten the nut, using the pump pliers.
Thread a drain hose clamp onto the dishwasher drain line. Slide the drain line over the little pipe that protrudes in the dishwasher wye tailpiece you installed in the double sink.
Tighten the screw on the hose clamp to secure the dishwasher drain line into the double sink drain. Turn the faucet supply lines if you turned them off as a precaution.
