We had a swanstone sink for almost 20 years…a white one. Swanstone is simply another brand name for Corian. We poured plenty of hot water into,that sink, draining pasta or whatever.
The sink looked brand new when we replaced it. As I noted upstream…if it could,have been undercounted, I would have kept it.
We never pour oil down the drain…we put it in a jar…and take it to the local landfill. Tiny amounts of oil from pans get washed down the drain, but not very often.
Cracks around the drain sound more like shoddy installation work than material defect.
As far as pouring hot water down the sink… Common sense, again, Corian or not. Don’t you all open the tap and get lukewarm warm water going while pouring pouring water off your noodles? Or do you prefer to be hit in the face with a hot steam cloud?
Bb, I don’t have that common sense. I pour hot water on the sink hole, draining.
BB, count me as another one without common sense. I don’t start the water running. It never occurred to me to do that. But I am able to maneuver the the pot so I’m not hit with in the face with steam. I’m not sure how I do it. I just know that has never been an issue for me. Next time I’m in that situation I’ll have to be more aware of my strategy.
…And that way, you already have the water going, so you can give the noodles (potatoes, root veggies, etc.) a quick rinse without having to juggle the pot and the faucet handle at the same time. 
I don’t baby my sink, and it is still fine after many years of daily cooking!
A sink needs to be a work horse!
Mine is!
What do you have?
Corian. 
I cook daily, dinners and breakfasts. I’ve dented enough ss sinks and scratched enough porcelain in the past, so I was open to a different option when we built the house 16 years ago. It turned out to be a good choice for us.
Why would you want to rinse your pasta or root veggies unless you are making a cold salad??
So it doesn’t stick before I drizzle EVO on it! A quick rinse also removes excess salt that did not get absorbed during cooking, but it does not make the pasta cold.
@BunsenBurner - I consider that burst of steam in my face to be a cheap facial sauna, al dente!
@wis75 - oil does solidify. Have you ever marinated something in olive oil and put it in the fridge? If it doesn’t solidify, it’s not olive oil. If you have winter, you have cold enough pipes in your sewer system for that to happen. Plus, it will just coagulate around other stuff. Other stuff ideally shouldn’t be there, but it is, especially hair.
You shouldn’t flush feminine products, “flushable” wipes, or “flushable” kitty litter. Even lots of food scraps down the sink are bad because the nitrogen from them can cause algae blooms in bodies of water that receive the treated waste water.
@BunsenBurner - I guess we have different pasta cooking techniques. I would never rinse my pasta as the starch on the pasta helps the sauce adhere. Try reserving some hot pasta water to add to the pasta and sauce if you have problems with sticky pasta.
I know why my pasta water is not hot. I boil it and turn it off the minute it boils so it can be el sentence. So by the time I drain them it’s no longer hot. Same with vegetables. It save gas and less cooking. I have porcelain.
Ok, here is what also can happen. Olive oil etc. can hydrolyze and produce fatty acids. These acids can form insoluble salts with certain metal ions that are floating around and the precipitates of these salts can clog the drains.

Take a look at the video in the link! Fascinating and scary. 
I need a sink/counters that are indestructible. S2 and DH will dump anything and everything – we have water all over the place, oil, BBQ grill racks, hot pans, etc. Asking them to take care of the counter/sink would not go over well. I’ve tried.>>>>>>>>>>>>
Concrete then.
Post #114, el dente not *el sentence.
Not concrete. Buy some of that black epoxy resin material used for bench tops in industrial chemistry labs. And a laboratory-grade Elkay sink. 
Have to put my 2 cents in. Agree about no oil down sink, nor meat byproducts - septic system or not. I have a 3 bowl porcelein Kohler sink (two large deep bowls, small middle bowl) - have loved it for 22 years. Use Bon Ami or Bar Keeper’s Friend to keep clean and looking great. MIL who had stainless steel was here and wanted to clang the pan in the sink out of habit!! - I had to tell her stop! This sink is not stainless steel! I want my sink staying nice looking! Here response was “I didn’t know”. Duh. There are a few very small scratches that are barely noticeable near the drain in the right sink after all these years (sink color is ecru). I have a plastic dish drain in the left sink, and now have a plastic base on the large right sink (OXO - is heavy plastic with ridges; put it in dishwasher when needed) - so I set hot pans/ceramic dishes right on that - more of a level surface too. Really nice to have that middle sink to always have available. Sometimes I set things in there to drain or thaw. Just handy. Also love my double bowl stainless steel sink in my laundry room. Those two sinks make my life easier! Also having a great layout of our home - kitchen not far from laundry, family room, bathroom. When we go to sell this house, will either have to upgrade our Formica counters or give an allowance for new owner to pick out what they want - unless it is really clear in the market place what almost all owners want. Have to weigh out having it done already, and the prospective owner saying “I want XXXX for kitchen counter-tops”.
