Hi everyone,

I'm embarking on a little project - replacing my kitchen sink. I'm going to post a couple questions to get started, and I plan to come back and post a photo of the completed results.

My sink is currently 6" deep. I want an 8" deep sink. Judging from the picture, do you think this is okay? My main concern is the right basin - I'm worried that if the sink is 2" lower, it may not have enough vertical pipe to travel through before hitting the P trap.

Oh, and that random white tube is the outlet from the dishwasher, but it came off disposal one day and I don't ever use the DW anyway. I left it alone.

Let me know your thoughts about a deeper sink. Thanks!

it can be nut to nut so it looks like you have enough but if not just use left drain for both and cap right

So nut-to-nut is okay? The tailpiece measures 2.5" (sans nut) so I think I'll be reeeeeally close. I'm trying to avoid reconfiguring the set-up to drain all to the left. But you know a lot more about what you're talking about than I do. I'll see what it's like after dry fitting with the new sink in a few days.

I agree. Run both bowls to the drain the disposal goes to now and cap the other off.

Are there any benefits to doing that, other than keeping things clean and simple underneath the cabinet? The only thing I've ever done as far as plumbing goes, was replacing 3 toilets in my house, but that was fairly simple. I'm pretty nervous about messing things up while trying to run both bowls to the same drain.

My wife is extremely iffy about me attempting to try it on my own - she would rather us pay the plumber. Plumber's asking for $510 total, which seemed ridiculous to me.

$240 (labor)
$60 (replace hot/cold shut off valves)
$60 ('extra' work resulting from changing the sink depth to 8")
$65 (install the disposal)
$45 (hauling the old stuff away)
$40 (required fee to drive out to my home)

Dont know about where you live, but around here that is a great price. I wont say how much I charged, but I just did a new kitchen sink install with garbage disposal and new undersink piping. My charge was quite a bit more than the $510 you were quoted.

The benefit is going to be not having to cut into the wall to lower the right hand side drain. In addition, it will clean things up and make life simple. Well beer helps too.

I live in Minneapolis. And thanks for chiming in; I thought I was being taken for a ride!

Is the new sink a double or single bowl?

 

[oh'mike]

If you do your own work --let us know---codes vary---JDCs set up would not be allowed here--

Dish washer drain not allowed to go to the garbage disposer---
P-trap for each sink----

A local plumber should know local code----but if you do this yourself----do your homework before starting===

Double - both bowls will be the same size, just deeper.

Could you clarify what JDCs means? Googled JDC, JDCs, and a number of combinations but it's bringing up nothing. Thanks.

Mike is referring to post #4 where both bowls are tied into one drain.

Sorry--this member is JDC---

What oh'mike said is very true. Codes vary and you really need to know what is and isnt allowed according to your code.

Why do codes vary? DO feces act differently in different locales? Or are PI's just full of feces in varying amounts?

Yes feces in the northern states are dangerous in the winter they become frozen projectiles in a sewer line an over pitched pipe can send a feces down the the line at an over accelerated speed damaging maybe a tee or a bend. or worse shooting up a manhole cover in the street :huh:

Of course feces acts differently.:wink:
Really, it's like anything else- money, politics, special interests groups, etc.

Finished. Replaced the sink, faucet, disposal, both shut-off valves, and all the PVC pipes underneath. Way too tired to snap a photo right now...and I'm really nervous about 1 PVC connection near the P-trap that's dripping about 1 drop every 30 minutes. Just tightened it really good, I hope that takes care of it.

The pros will have a laugh at this- it took me 8 hours, no breaks. I think I could've finished in 3-4 hours, but the old disposal was really stubborn, took about an hour. Also I got a new stainless steel Kohler sink, but the clips underneath were the most difficult thing - that part took 3 or 4 hours.

To other DIYers who happen to come across this thread in the future, I would suggest taking a good hard look at the mounting hardware that came with your sink, and consider buying something else if it looks impossible. Just that part alone made me think "wow, now I understand the installation estimate I received".

Would I do it again? Well, I saved about $500 but if this was to be repeated with this same sink I purchased, I would say no - I would hire someone and pay the $500.

Time for a shower. yuck.

If that compression fitting continues to drip--disassemble that section and feel the mating surfaces---some times a tiny bur or ridge of casing flash will cause a drip--if it's got a burr--remove it with a scrape from a knife blade----

 

[jagans]

Yeah, its those nylon trap washers and that little ridge at the form for injection molding the P trap. Nylon does not form like rubber. You would think they would have figured that out by now wouldn't you? Emory off that ridge, and try again. Fill the sink and pull the plug for a real test.
