A good, general rule for a vacation rental property is to remove unnecessary items that may fail and cause you a repair bill. I would include things like complicated small appliances, ice makers and trash compactors in this category. Because I market my property as a high-end home, I do offer a few items that some might include in this “unnecessary and likely to break” category: a dishwasher and a garbage disposal.
It is my opinion that both are actually necessary items. A beach house without a garbage disposal and dishwasher would be more akin to a camping trip. Are guests going to feel like they are staying in a high-end rental if they are cleaning a sink trap after every meal? Clogged drains are even more likely to occur than a jammed disposal. So I consider a garbage disposal a benefit to the vacation rental owner as it prevents plumbing backups…and those are actual emergencies! Disposals are a must too if you have a dishwasher. Therefore it is my recommendation you provide both.
While I have never personally had trouble with the Insinkerator Badger 1 
disposal at our unit, without question the number one reason I have been contacted is for trouble with it. Maybe some of these folks have never used one before or maybe they have more industrial versions at home. Either way, it has been a bit perplexing as to why all the trouble. It has been described as “jammed”, “stuck”, and just “not working.”
In most cases, any disposal that is jammed can be reset by inserting an Allen wrench underneath or pushing the reset button. I understand guests do not want to spend their precious vacation hours even doing that. One thing I do NOT understand is how people can lack common sense with the items they put in the disposal!
I debated installing a special strainer like this here. However, people would probably just pull it out.
Since I am tired of the calls, I decided to upgrade. My goals were to find a disposal that would grind virtually anything and one that had a decent warranty. I found and purchased a Waste King 9980 1 HP disposal. A triple grind, continuous feed system will grind almost anything and the warranty seems unbeatable…full lifetime warranty with free in-home repairs!
I believe Waste King can only be found online. I purchased it on Amazon…you can find it here. At that time, I purchased it for $168 and the good folks at Lenegan Plumbing performed the install for $110. So $278 all in. About the same amount I spent last year for two service calls. My thought is that if anything goes in the disposal, crazy or not, it will be obliterated.
I will update this post if I should encounter any issues but I expect to no longer hear about the disposal being jammed!
