Back story is I learned the hard way not to scrimp on a disposer - we had a rental house some yrs ago that had an old badger 1/3 hp that I never gave much thought - previous 20+ yrs was with disposers in rural Maine so just having one was a new experience. I don’t realize its limitations and got it jammed. After unjamming and spinning freely by hand, it still refused to run. So I replaced it with the next bigger 1/2hp. I was surprised at just how much better it worked. Then when we bought a house, it already had a 3/4 hp disposer of a different brand but still was a beast munching easily on chicken bones and all types of fruit and vegetable peels. Now convinced a good 3/4 hp is worth the extra expense.Fast forward a decade and we’re buying a new house. Asked builder to upgrade the disposer and I’d pay the difference. Unfortunately they buy in bulk so no choices on appliances. Ok, no biggie, I’ll upgrade myself - been there done that, can do it again!. Been here two weeks and definitely not thrilled worrying about every thing I drop into the disposer. The 1/3 hp moen is only fractionally better than the 1/3 hp badger since it runs at a higher rpm. Anyway, started my research and settled on a ISE 2 stage 3/4 hp as best bang for the buck - Costco had best price but it looks like a custom for Costco model, discharge is an inch or so lower and we got a straight shot so wanted a more compact model so discharge would line up better with existing. Best price was Amazon or Lowe’s for the 3/4 hp Advanced or Compact - both 2 stage. But figured to wait for the holiday sales. Sure enough Amazon posted the Evolution 3/4 hp for a good savings or actually about a break even when adding the stupid ez connect plug since it only comes with the hardwire connector. A shameful ploy by ISE marketing to squeeze out an extra bit of profit on these units.Anyway, 2 hrs or so to remove existing moen and install the new evolution, including the 5 mi trip to HD to get the cord. The marketing literature for the moen says it uses the same 3 bolt ez twist lock so I didn’t remove the sink collar. The only hassle was when trying to remove the lock ring, the whole collar assembly would turn, so I had to pry the lock ring against the bulge on the collar where the jack screws connect. Enough prying got the old moen to finally release. The plumbing is pretty new so I just removed the dishwasher hose, loosened up the discharge piping, removed the discharge nozzle flange bolts from the moen, and turned the other side sink trap a bit so the connecting tee would allow clearance for pulling off the discharge nozzle. The old unit simply slid off now. When I got the new unit locked into the collar, I just slid pipe nozzle back into the tee, turned the piping back to align, and bolted the flange onto the new disposer, then snugged up the drain pipe fitting at the tee. The disposer hose fitting was the same size so just removed the evolution’s sealing plug, pushed the rubber connector onto the fitting and tightened up the hose clamp.All seems fine. Filled sink with water and no apparent leaks. Initial runs have been smooth and exceptionally quiet. It feel robust, even with the outer plastic shell. It’s a bit lighter than I expected which made it that much easier to install. At 70, I’m not as strong or as flexible anymore so it was very pleasing to find it was easy to handle. So far I’m really happy with it. Obviously, time will tell how well it holds up. But I’m expecting it will outlive me!
