I'm planning on installing a somewhat large single tub 33x22 kitchen sink and am concerned about it supporting a 20+lb insinkerator evolution disposal. I had my eyes on an Elkay sink so contacted their support and was informed the sink is not compatible with the disposer.
Curious on any experiences with this? I'm guessing a single tub 20 gauge 33x22 sink may be a lot weaker than say a 2 tub version but I can't see people buying special sinks for disposers like this? We want a single tub for washing large pans. I'm thinking the sink may work fine and Elkay just doesn't want to be responsible for it.
I was going to go for a Kohler cast iron sink but the wife hates how black shows all of the imperfections and she insists the sink be either stainless or black.
STEVEusaPA: I think I have that now.... I'll measure it when I get home, but I got the biggest, deepest single bowl undermount sink they had, and put a garbage disposer on it (don't know the weight) Never had a problem, even with big pots in the sink filled with water. Been about 6 years now.
ChrisJ: Weird I really think Elkay is full of it but I have no way to know for sure. Kohler said every kitchen sink they make will support it no problem at all. The sinks I'm looking at are top mount so Id think its even less of a concern than bottom mount. Elkay recommended two sinks in the $600-700 range. Don't get me wrong they are good looking sinks but a bit out of my price range.
icesailor: Single bowl sinks: I have lost count of the number of Elkay PSRS 3322 ("S" means single bowl) or LRS3322 sinks in my career. It is basically the only sink I recommend of you have a 36" sink base. Elkay isn't the only SS sink manufacturer. Kohler has a line. They will all support standard food waste grinders, especially the ISE Evolution series. IMO, avoid cast iron porcelain sinks like bad hangover. Over time, they will rust under the seal between the counter-top and the sink. The finish will dull, and it can wear off or chip. Depending on the cleaning impulsiveness of your wife. I have seen the finish worn off around the throat from scrubbing with abrasive cleaners. The cast iron sinks aren't very deep. If you are thinking about a double bowl CI, by a 25" single and you will get one bigger bowl than the two smaller double bowls. If you get a 33" sink with the smaller bowl on the left, the larger bowl is the same size as the single bowl sink. You can get the SS bowls in deeper models but I haven't seen them to be all that useful for the additional price. I have no idea why Elkay told you what they did. Perhaps there was a misunderstanding. And if you are worried, you can always slide a block of wood or a piece of 3" PVC pipe under the disposal. I've never needed to. If you are using a composite or stone top, I suggest NOT using under mount bowls. I have seen a large number of them pull away from the counter-top. What a mess. My opinion only.
Gordy: Top counter mounted 20# insinkerator Be aware the larger the disposal the higher the odds of plugging up the sewer line!!
ChrisJ: Sinks and fun We're highly considering this nice Kohler sink. Gordy, I thought these 2 and even 3 grind stage Insinkerators were pretty good as far as grinding stuff up enough? The one I bought is an Evolution Essential pro so it only has 2 stages but it seems pretty decent. I need to pick up a spool of 12-2 NM-B this weekend and run a nice new 20A dedicated circuit for it. Also I'm proud to say our house will have one less S-trap after this project. Thanks for all of the replies and help!
ChrisJ: So I'm trying to plan my drain piping and wanted the opinions of some pros. Obviously there are tons of ways to do this but I'm curious what is the smartest? What will allow for either my self or a plumber to clear a clog if ever necessary? My thoughts are the cleanout directly below the right drain will allow cleaning of the trap towards the back. This is what I came up with assuming I have the room. Sorry the drawing looks like a child did it and it is not to scale but I think it gives an idea. I'm not sure what effect the bottom horizontal tee will have on flow, for all I know it may cause a clog it self. All piping I picked is glued PVC except for the tailpieces. I also bought two traps, one has a cleanout, one doesn't. Not sure which is better as I'm not sure how useful that cleanout even is. As always look forward to ALL and any comments and opinions.
heatpro02920: I thought you were getting a single bowl sink wouldnt that only have one drain? I don't do plumbing professionally, but have done it in all of my home builds, my mothers, brothers, ect.... First I hate garbage disposals, I have already went down this road, they are just not for me and my family... But anyway, if you are worried about a leak, install a cleanout tee with a straight shot out... and get traps with drains, I use the sched 40 for everything, none of that flexy or thin wall stuff, a pvc desanco adapter and a fernco rite where the pvc drain comes under in under the sink, so worse case you can detach the fernco and the tail piece and remove the entire assembly as one piece, do your repair in the garage and replace it under the sink.... Also for the garbage disposal install, when I installed my disposal {which is no longer there} in my old home, I had an older large single tub stainless sink, that my licensed plumber employee said was too weak for a disposal, so I put a piece of unistrut under there to hold up the plumbing and take the weight off the sink, screwed it to the wall with rubber mounts and it actually quieted down the entire setup.... But I think the sink would have held it, where is it going, I stood in them things before... anyway good luck, hope this helps, In my experience kitchen sinks dont clog much {unless you have a disposal, lol}, I have a customer that has a saniflow macerator under his sink, on his small second bowl, that pumps separately, he said he can put chicken bones through that thing, lol... I did notice these things are getting huge titan makes a 1 1/4hp unit, thats a lot of power for a gd. GE has a 1hp model that suposingly works very well, just do your homework {which it sounds like you are} because they can be heart breakers... you start doing the math, this thing costs $200 last 6 months and they wont cover the warranty because it wasnt installed by a licenced certified tech or what ever they can say to get out of it and it costs you $35 a month for a garbage disposal...
ChrisJ: Dual or single Yep I wanted a single but the wife changed her mind and we went with a totally different shaped two bowl sink that should work for both of us. Btw, I put a turkey leg down a disposal in an apartment we had before we moved here. And yep.... it ate it. Now I probably won't be doing that to mine even though its twice as strong. But chicken bones, absolutely.
Paul48: single tub Two drains? The dishwasher drains into the disposal, by way of an air gap. You don't need the tail-piece adaptor for the dishwasher.
ChrisJ: OOps Obviously I should have made it clear we switched to a dual tub. I'm sorry, I feel like a dope now. If we put the disposal on the left side I'd kinda prefer a tailpiece for the drain as the hose comes from the right side and neatness counts. Is there any downside to doing it this way?
