Hi guys,
I have recently replaced my sink but in doing so I think I have created a backflow problem. Currently, I have a 2 bowl design with a garburator on one side and the dishwasher discharge on the other. When I installed the new sink, I had to redo the drains as the new sink was and inch deeper than the old and the drains were set further back.

Here is my problem. When using the sink there is no leakage that I can see from anywhere, but when we use the dishwasher, the garburator on the other side starts to leak through its body (water coming out of the base of it). I do have a p trap on both sinks but had to do some finageling to get them to fit right. My stand pipe is a 3 way coming out of the wall but the bottom of it is lower than the bottom of the current sink.

First, what whould cause the disposal to leak with water coming back through the p trap. Shouldn't that water just collect in the disposal and drain normally when the dishwasher finished it's drain cycle?

Secondly, if I do have to replace the disposal (insinkerator badger 5 at 5 years old) any advice on a new one?

First, check the connection of the dishwasher drain hose (or air gap, if you have one) at the disposal to insure that it is not leaking there and running down the side of the disposal. If the leak is indeed from with in the disposal and coming out the bottom, you have a defective disposal. Replace with the same 1/2 hp Badger 5 model.

In addition to Harlold's advice: Check connection of garbage disposer's drain outlet. There is a flat washer between body and drain. Also, make sure all 3 pegs on GD collar are engaged to the drain inlet. Gently tap them with hammer until you feel they won't go any further. Since you replaced sink, you had to also replace GD strainer. Make sure it is installed properly with thick black washer on the bottom and plumber's putty on top with all 3 screws tightly screwed in.

Back to you. Milo

When I had replaced the sink I made sure I paid attention to how it all went back together. So I know that the keak is not between the sink and machine. There is no black washer between the gs and the drain. The gs has a 90 degree bend to its output side then directly to the inch and a half or quarter drain pipe. I looked into the gs and found that othera are having body cracks as early as a year of use. Im just foing to replace it anyway. Easiest thinf to do...

There is a large flat washer between that 90 degree bend and garbage disposer. If compromised than water leaks through the body of the unit.

Advice: Badger I and Badger 5 are not good garbage disposers. Get one with stainless steel interior parts. They start at about $135.00 and up in my area. Otherwise, you will be replacing it in year or two again.

Good luck ! Milo

No doubt on the quality of an 80.00 major appliance. Lol. Ended up finding evolution compact for a respectable price and decent reviews. Cost 2 times as much as badger but has stainless steel interior and quiet (ahem) technology. Once badger is off and tupperwear removed from leak catching I'm going to take it apart to see exactly where the leak was from. The more I think about it I am pretty sure it's a cracked body. Someone suggesyed impeller seal as well. The large flat washer by the way is diamon shaped and is still sealed. Leak is on the opposite side of the unit. Yes I know water can flow strange ways but it will always flow down before it flows across.

I love human curiosity ! LOL !

Yes, Evolution series disposers are very well made. You've made a good choice. Even the least expensive Evolution disposer is far (far) better than Badger 5.

Stop by if you need help with installation

Lol I appreciate the offer. I think its more along the lines if I can figure it out I might be able to figure out a solution to offer others with the same problem. If it is a crack possible to use jb weld to fill cracks. Not a long term solution but it might give someone who can't afford a new one right away a couple of months of leeway before it explodes.

Make sure all 3 pegs on GD collar are engaged

I find that rather frustrating at times. I can hold the disposal up with one hand but have difficulty at times engaging the locking ring with only one hand. I guess my hands are just not big enough.

Do you and others have this difficulty or is it just me. Thinking of making me some kind of lift.

Use some telephone books or 2 bys to get it into position. Then you only need to lift a bit. As for getting it to turn in. If the sink flange isn't tight enough it will rotate. Tighten it a bit more and once the gs is started on the threads use the breaker wrench in the holes as leverage to turn it as per the instruction manual.. :-)
