Garbage disposal drains slow, why?


Hi All,

I installed a new garbage disposal then after using find it drains very slow some times then not others. I had the basic 3/4 GD installed and recently swapped it out for this unit:

http://www.sears.com/kenmore-3-4-hor...1&blockType=G1

install was basically a direct swap, no modification of piping needed and when apart I ran a snake down the pipe making sure clear.

Original GD drained just fine but now with the new one installed sometimes it drains fine then others (most of the time) it drains very slow causing a small back up in sink then its like an air bubble gives way and empties sink and drains as it did.

What could be causing this and more importantly how do I correct? I pulled it off yesterday and made sure line is cleared, I ran some drain cleaner down it after I ran the snake and when I first installed disposal I did not tighten the GD drain line into house drain line and it seemed to drain really well. After I tighten that it eventually went back to the problem with slow drain.

I'm stumped so any help is greatly appreciated!

rare, but I have seen it---the rubber cover does not let in enough air---force it open and see if the problem goes away.

Next--check and see of the drain pipe is low enough----post a picture of the piping and machine--

As oh'mike mentioned. Those sink drain baffles these days don't have a ton of room and with a little bit of food they can get sealed up. Happens to both of mine all the time. Generally you just need to give it a little nudge to break the seal and you are good to go.

Thank you I (or should I say you) found the problem and a solution, it was the rubber baffle. I held open two flaps then ran the water several times every time it drained just like before! I love this site!

Bad venting and all of the crud in the drain line are the two culprits that usually cause these. Was there a lot of built up gunk in the piping when you pulled out the old unit? You could try using Baking Soda and White Vinegar to see how that works in loosing up everything.

While you are waiting for the Vinegar and Baking Soda to do its thing. Heat up as much water as you can on the stove to boiling. After you get the water boiling, take it off of the stove and pour it down the drain to get any crud that was loosened up, to flush out.
