Steps to Install single bowl sink with garbage disposal

Shut down power supplies:

First, shut off all power and water sources.

Take Out Your Old Sink:

You may now start taking out your old sink. Make use of one hammer and one screwdriver to remove the wash bowl. Before you remove your sink, you must take out the screws.

We can use a drill and a single plumber’s snake to remove all the pipes once you’ve taken out the wash basin. We’ll need a tool to pry them apart.

Add a new garbage disposer:

The bottom of the wash basin should now include the garbage disposal flange. To attach, the mount needs a 1/4″ and 3/8″ borehole. Check the manufacturer’s instructions to determine whether your model must be re-calibrated.

Power The Disposing Gadget With Electricity:

An electrical supply may now be provided to a sewage disposal system. Use your wrench to tighten the nut on it to do this. Connecting your power supply is next. Verify that the plug is inserted firmly. The final step is to turn on your power supply and watch for the garbage disposal to start working.

Check for leakage:

Leaks might be found using the pressure test. Utilize a pressure gauge to look for any leaks. A sink is comparable to a reservoir. You may start the sewage disposal system after filling it completely with water. Water may spill from the wash basin if there is any leak.

Replace Your Drain Component:

The drain component installation comes next. This may be done by using a wrench to tighten your drain pipe.

Fix your faucet:

Lastly, attach your faucet to a sink for washing. Both must be tightened with a wrench. Once you’ve connected it, you may test the faucet. It would be beneficial if you first switched on your water supply.
