Installing a granite double sink with garbage disposal

I just got a granite double sink off craigslist. Haven't got the faucet or disposal yet. Having a hell of a time trying to find a video or even some instruction on how to install top mount granite sink.

My other question is about garbage disposal removal. So far everything I read something about removing wire attachments but mine is a plugIn.

1. What material is your counter top?

2. Most new garbage disposals come with an electrical cord. If the GD you buy doesn't have one, remove the old cord from the old disposal and connect it to the new disposal.

The disposal I'm thinking of buying, comes with a power cord. The countertop is plain laminate.

A new sink usually comes with a template, to use in cutting the rough opening in the countertop. Since you don't have a template, you'll need to make sure the sink fits in the opening. Opening too small? the sink won't fit and the opening has to be enlarged. Opening too large? the sink won't securely rest on the countertop. In this case this sink won't work.

There are demos on youtube you can watch. If you find this job a bit too hard for you, hire a plumber.

The granite sink is the same measurements as my current sink only difference is the bowls are deeper. So I'm not worried about the opening being too big.

A granite sink should be heavy enough that you won't need any fasteners to hold it in place. Just put a bead of caulk around the edge of the countertop (I seem to recall that you shouldn't use silicone; I could be wrong) and set the sink in place. Let the caulk set up.

It may be easier to attach the hardware (faucet, drain basket, garbage disposer ring) before setting the sink in place.

There is a ring attached to the sink that the garbage disposer attaches to. The garbage disposer is usually attached and removed with a twist.

If the new sink is deeper than the old sink , then you have a tighter space for your drains and your garbage disposal. Select a disposal the will fit in this tighter space under the new sink.

If you run into problems, such as adjusting your drain line, it will better to hire a plumber.

Oh thought I read to use silicone sealant but I check again. Will do on the hardware, got the faucet today, now just need to get the disposal.

Adjusting the tubing/PVC pipe for the drain line shouldn't be too hard since I had to do that when installed a sink in my bathroom.

It looks like you have every detail figured out, and you are good to go.

Let us know how it went.

You will want to verify that, many do not and it may not be clearly marked on the box. I just bought a new Badger and it comes without. Regardless, if you need a cord, you can salvage the one off the existing disposal.

With the granite sink, makes sure that it is a top mount first, if not you could be in for a rude awakening when it comes time to fit it. The next thing is that you want a minimum 1/4" support around the perimeter rim of the sink. That is to say that the counter should extend under the sink rim by at least 1/4" on all sides, more if you can get it.

Do verify the proper caulk for installation, I recall that silicone can stain stone. If this is a cultured sink, then it may not matter.
