My garbage disposal quit working a months ago, and along the way I also noticed that the disposal side of the sink(2 basin) seemed very slow to drain. This past week, my dishwasher also started overflowing(primarily out the overflow, but on one occasion out the front-that was accompanied by the disposal side of the sink filling up with water also).
I finally buckled down this evening and pulled the disposal off. AFAIK, it's original to when the townhome was built in 2006, and it's pretty nasty and crusty(and totally seized up). I capped off the drain on that side of the sink, and filling the disposal with water it's VERY slow to drain out-I'm guessing this is the source of both my dishwasher and slow basin drain(the dishwasher drain is connected to the disposal). Given that there's no wiring to speak of involved(it has a standard GFCI outlet under the sink that the disposal plugs into) I can't imagine that replacing it is beyond my capabilities. Aside from cleaning up the flange in the drain and putting some fresh plumber's putty around it, it looks like a bolt-on job.
What I just pulled out is a Badger 1 1/3 HP. It seems to be the same as this https://www.lowes.com/pd/InSinkErator-Badger-1-1-3-HP-Continuous-Feed-Garbage-Disposal/1267193
That seems the obvious replacement since-assuming it hasn't changed in ~13 years-it should bolt right on without any plumbing configuration. For obvious reasons, that gets a strong nod.
With that said, I'm wondering if it's worth an upgrade. I'm going to be moving/selling in the next year. I hate to kick the problem to the next owner, but at the same time longevity isn't a huge concern for me. My single biggest use for it is to dispose of the remains of the couple of apples a week I eat, and it rarely sees much beyond other fruit(oranges, peaches, and the like).
Is it worthwhile to step up to a 1/2 HP unit? What about a different brand? There again, I'm trying to avoid a plumber bill(I'm still hurting from a water heater two weeks ago, which was extra expensive since whatever moron designed the place thought a closet 8 ft in the air was a good location) and would prefer something ideally that's as close to plug and play as I can make it. FWIW, the current plumbing configuration has a rubber flex hose coming in for the dishwasher drain, and then a PVC attached out the side using what looks like a distributor clamp on an engine. It's about a foot of straight PVC pipe over to where it Ts with the drain from the right basin, and then the combined ones run down into the trap and from there out of the cabinet.
Any thoughts on this?
