This was bought to replace an older Insinkerator Badger 0.5HP. The previous model was atleast 7 years old and perhaps even older depending if the prior owner of the house replaced it. We used ours very seldom, opting to use a sink strainer most of the time. Our older model started leaking through the motor housing, which indicated that something rusted thru on the top, not good!
We wanted something a bit more powerful and something that can easily be installed in the existing fixtures. I reused the sink mount and the drain hoses as they were already precut and fit my existing piping.
Install Tips: - Have a small bucket to catch any water or backwash. - Have a rag handy to sop up any splashes. - Remember to punch out the dishwasher plug if you plan to use that feature. - Plan for about an hour for the whole install from start to finish. - Use some pipe joining compound to make things a bit more resilient (I used Oatey)....this is especially useful if you plan to reuse the pipe fittings like I did. - Remember to purchase the wiring if you don’t already have it (reuse).
Install: Instructions were easy to follow. Read them twice and make sure you visualize how you plan to do it in your particular install. I reused the wiring from the older model. Took 5 minutes to swap. Make sure the ground wire is making a good contact!
Installation was moderately difficult. Just the sheer small space under the counter and the weird angles. Using the pipe joining compound was a bit messy but cleaned up easy.
With patience and doing things correctly, the Insinkerator 5XP worked like a champ the first time around.
Final Notes: - The sound is only very slightly more than the 0.5HP model, I would say mostly the same. - The motor is powerful and I definitely noticed the difference in chewing up food waste. - The interior parts are galvanized, so I expect to replace again in about 7 years or more with moderate use.
