My Insinkerator Badger Model 100-1 only lasted about 6 years before it started leaking from the bottom and I was disappointed that it didn't last longer. I live alone so it really isn't used that much. Top leaks, side leaks apparently are fixable. Bottom leaks not so much. And mine leaked from the bottom. Walking through the kitchen at night and stepping into a puddle of water is surprising. Looked around for a replacement that would be easily installed. Looked at some videos. Decided that my best bet would be to install what had been installed before. Ordered it from Amazon. Had it in less than a week. Watched the Insinkerator replacement installation video again. I was a bit concerned about the condition of the packaging when it arrived. The box was extremely dusty and looked like it had been rolled around in a cement mixer for a few hours. The foam packing was just about pulverized. Unpacked it and it looked fine. Plugged it in for a quick check and it worked. Checked the serial number which also gives the date of mfg. 2020 and in August. Fresh from the factory. Re,moved the old disposal. Very easy. First unplug it. The directions say to pull the circuit breaker but I just unplugged it. Disconnected the plastic pipes and then I used the original and replacement keys to unlock the retainer ring at the top. Very simple, but remember that the disposer weighs in at about 13 lbs. And when the ring is loose the disposer just drops free. Make certain that you have it supported. Old one came loose easily. Took it out. Lined up the new one for replacing the pipes and turned the lock ring to hold it all together and then plugged it in. i suggest that you go with the one with the power cord already installed as that makes the replacement that much easier. Made certain that all fittings were secure and the lock ring tight. Turned it on and ran water. No leaks and works fine. Has now for about a week Disappointed that the old one didn't last longer but happy with the new one and how easy it was to install.
