My sink started leaking – it looks like I need to replace all of the seal/gasket type things between the basin and the garbage disposal.
Top side:
Bottom side:
I am guessing that the steel part on the top side can be disconnected from the black plastic part, but I don't know that for sure, so I'm not going to go ripping at it until someone on the internet tells me to.
How do I seal each side of this back up?
The model is Pulverator P10. I couldn't find a manual online.
I'd like to thank everyone participating and up-voting. I went to home depot today and bought a new air gap. Upon a further inspection I found out that my air gap is missing a cover: a piece of plastic that routes the water coming from the DW into the drain.
Long story short, it somehow got popped out and my wife "saved" it by sticking into the kitchen drawer.
For inexperienced DIYers; or any body not really comfortable with plumbing in general, the easiest option is to replace the whole faucet. While the faucet may be serviceable, stuck screws/bolts, proprietary disassembly steps, and difficulty finding replacement parts, make this a frustrating job for beginners.
The new faucet should come with instructions on how to install it, but here are the basic generic steps to remove the old faucet and install the new one.
Look under the sink, and you'll (hopefully) see something like this.
Actually, you'll see two. One for the cold water, and one for the hot. Turn the knob until the valve is shut. Then turn the faucet on all the way, just to make sure the valves are fully closed.
If you do not have valves under the sink; or the valves do not stop the flow of water, you'll have to shut the water off using another valve down the line or the main shutoff valve.
Attached to each of the shut off valves, there should be a hose like this.
In some cases a rigid or flexible copper pipe will be used as a supply line, instead of a flexible braided supply line.
Using a pipe wrench or tongue and groove pliers, disconnect these pipes from the valves.
Make sure you have a small bucket under the connection, to catch the water that comes out of the pipe. A small amount of water is normal, it's just the water that was left in the pipe between the shutoff and the faucet. If the water continues to flow or comes out under pressure, tighten the connection back up. This means the valve is not working or has not been fully shut off.
If you follow the supply lines (the pipes you just disconnected) up, you'll find the tailpiece (a long threaded pipe) with the mounting nuts at the top against the underside of the sink. There may be two (one where each supply line connects), or just one in the middle depending on the faucet make and model.
A basin wrench makes removing these nuts much easier.
On some faucets, the supply lines are part of the faucet and cannot be disconnected. In this case the mounting nut may or may not be right at the end of the supply lines.
Once the nuts are removed and the supply lines are disconnected from the faucet (if applicable), the faucet should just lift away from the sink.
Once the faucet is removed, scrape any old plumbers putty from the top of the sink using a 1" putty knife
Now that you have the old faucet removed, it's time to install the new one. Follow the instructions included with the new faucet, or these generic steps.
Grab some plumbers putty, and roll it into a "rope" (about 1/2" or so around) in your hands. place the putty rope either on the sink where the faucet will sit, or around the bottom of the faucet itself. The plumbers putty prevents any water that may be near the base of the faucet, from leaking down into the cabinet below the sink.
Do not use plumbers putty on natural stone (granite, marble, etc.) counter tops, use a bead of 100% silicone caulk instead.
Carefully put the faucet in place, and press it straight down (don't worry if some of the putty squeezes out, that's normal). If the faucet does not stand on it's own, get a helper to hold it for you. Go back under the sink, and install and tighten the mounting nut(s) on to the tailpiece(s) using the basin wrench again.
Remove any excess putty that squeezes out from around the faucet base.
If the old supply lines are still in good condition, you can reuse them. Otherwise, head to the hardware store and pick up new ones (if not included with the new faucet). Make sure to take the old supply lines with you, so you get the right ones.
Using the basin wrench again, connect the supply lines to the threaded tailpiece(s) on the faucet.
Connect the other end of the supply lines to the shutoff valves, making sure to connect the proper line to each shutoff (you don't want hot water coming out when you turn the faucet to cold).
Slowly turn the shutoff valves back on, and watch carefully for any leakage. If you see a leak, turn the valve off and tighten the connection where the leak is.
Turn the faucet on (testing both hot and cold), and look for any leaks.
Use PTFE thread seal tape on all threaded pipe connections, to reduce the chance of leaks.
If any of the threaded connections are difficult to remove (when removing the old sink), soak the connection in penetrating oil.

Plumbers putty , in a 3/8 in thick rope circle, goes under the top part.
It helps to have a helper push it straight down and keep it from turning while the jamb nut and rubber washer and (sometimes paper) thrust washer. The rubber washer goes against the sink. The thrust washer goes between the rubber washer and the jamb nut.
If someone used some thread dope previously, get the mating surface of the sink cleaned off.
If the rubber washer or the thrust washer is deformed, replace them.
