Question for single sink with garbage disposal owners . . .

Posted by gardenburgher (My Page) on

I use to have a double sink with a garbage disposal on one side. Never had a problem. It was a 10+ year old GS that practically shook the house down every time I used it, but otherwise no problems.

Our new single, Silgranit sink and Insinkerator GS were installed last week. Im annoyed because water doesnt easily flow down the drain. The GS flange backs everything up. I either have to run the GS and run water down at full force, or manually hold the flange open (GS turned off, of course). This happens when its just water . . . no waste in the GS.

Is this normal? Something Ill just have to get used to?

Another question: When I reached in to open the flange, the whole thing came right out in my fingers. The ring easily pops in and out. That kind of surprised me. Isnt it supposed to be attached?

Thanks!

BY "GS", I meant "GD" (garbage disposal). I have no idea what I was thinking!

Is your new sink considerably deeper than the old sink? If so and if the waste drain wasn't lowered to accommodate the new deeper sink that may be your drainage problem. The plumber should have discovered that when he installed the GD.

I don't know about the flange, but I've read somewhere that with new garbage disposals the rubber part can come out for cleaning. Just a guess.

Call your plumber back up and describe your drainage problem and see if he agrees that the waste drain should be lowered. I think that is an expensive fix because the back of the sink cabinet has to be cut out, the dry wall opened up, the waste drain cut and lowered and re-assembled and the dry wall replaced. I've read on the plumbing forum that the cost for a plumber to do this is anywhere from several hundred dollars to the highest I've read of $1800. It may be a harder job with the sink already installed.

Also, are your shut off valves now behind the deeper sink? I'm worried that we may have to lower those also to be able to quickly shut off the water to the sink in an emergency without having to try and reach behind the sink.

Let us know what you find out. I have the same concerns about our kitchen sink waste drain height but we haven't started renovation yet.

Good luck.

What GD do you have?

Here's a silly question as well...could you have the flange in upside down? My dh installed our GD and when I came home something didn't seem right. Water was backing up so I stuck my hand in and tried to shove and fiddle with the rubber. The flange came out like yours and I noticed dh had it in upside down.

Once I righted the flange the water flowed freely. It's stiff still though, so waste doesn't just fall down the drain yet.

yeah, the flanges are pretty stiff and rigid initially. they loosen up over time. our new one does the same thing sometimes.

try taking it out and flexing the rubber a bit, opening and closing it a few times, to kind of stretch it out.

and, yes, they're easily removed now, for cleaning. the fact that they used to be attached was a negative, since they'd get all gooky and start to smell after a while, so most manufacturers are making them like yours is now.

We have a large deep single bowl sink and an Insinkerator GD and we're having no problems with drainage. We did have some concerns about the issue jb1176 mentions: Our new sink is many inches deeper than the old and changes had to be made to the height of the drain line. Apparently that did the trick and now it's draining perfectly.

Thank you all for your fast responses. I will try all of your suggestions:

1. Make sure the flange isnt in upside down!
2. Try to stretch out the rubber a bit.
3. See if the waste drain needs to be lowered.

Im really hoping it isnt the waste drain. I went from a 6" to a 10" deep sink, so Im afraid that might be it.

Thankfully, the shut off valves are still easily accessible.

Chrissiemw, I have an Insinkerator Evolution Compact.

Thanks again!

Gardenburgher...

I have the same GD. Hopefully the fix for you is as easy as it was for me!

I almost threw a fit when the water wasn't going down. Then I started fiddling with the flange and noticed it was in upside down. I was so mad, thinking that dh installed it wrong and it was permanent but then it came out with a small tug...we didn't realize they make them removable these days. Thank goodness for that though!

When did they start making the flange removeable? My SIL & I both bought Insinkerators 5-6 years ago & both of us have the same slow draining problem (not so much a problem as an irritation). Hers was an add-on to an existing sink & mine was installed by a plumber as part of a total renovation.
