Moen 169031 Optional AC Adapter Service Kit for Moen Kitchen Faucets with MotionSense

Working very well and with accurate output.

Update: it has been five months since we purchased this. So far, so good. It works perfectly and the batteries are still in place and not changed. It is nice to have this ac adapter. Dec 2020) Now here is the original review: It works well; it was super easy to install. It is nicely labeled so anyone could make the connections/plug in the cords. Without it, our batteries lasted 5 weeks of frequent use by two adults and two teens. After changing the batteries twice, we got this setup. I am sure everyone thinks Moen should have included this setup into any of their wifi faucet boxes. Also, I am sure everyone says "ouch" at the price of this power supply and tiny control box so you can see the lights to determine if AC current is in use, or if batteries are, or if batteries need replacing. I read reviews that say yes, the faucet works in a power outage or if batteries are dead-just use the faucet-and that is just not so. No power, no water period. If the batteries go down to 20% and you do not have this power supply, your faucet temporarily disconnects from your wifi and no, you have no water. So you absolutely 100% want this power supply so you are not using batteries 24/7 and only just when the power is out (think windstorm has knocked out the power lines). With this power supply, your batteries are a backup; they should last a long time. So this is a great product, it works, and I can recommend it. You simply have to have it or you will be swapping out your D cell batteries every month. I think the faucet battery pack is supposed to use "regular batteries" and not lithium batteries. The point is if you bite the bullet and buy this, it is easy to install and it works; you are off battery-changing protocol.

Better than having to use batteries for the faucet.

I purchased this AC adapter for my Moen MotionSense kitchen faucet. Thankfully, I read a review here before I made my purchase. Yes, this AC power adapter works seamlessly with the provided 6 AAA battery power pack which comes with the faucet. However, when you plug it in, there MUST be constant power to the outlet you plug it into. I realize this seems like a given, but (as noted by a previous reviewer) if the outlet powers the garbage disposal which is controlled by a wall switch, you have to get a countertop mounted garbage disposal button installed as well. Easy! This button allows you to leave the switch on to power the under-sink outlet, then you plug both the faucet AC adapter and the garbage disposal. My InSinkErator garbage disposal countertop button even has an addition outlet on the under-sink control power box! I’m thankful to have I read about the power issue in a review here, so I hope this review helps you! Fabulous not having to change batteries, and this adapter can be used with/without the battery pack. However, plugging in the battery pack gives you backup power if there’s an outage.

This kit is perfect to convert the battery operated faucet into AC powered, yet keeping battery as the back up. Because if there is no AC power the faucet will not work and hence you also have NO WATER! Its expenseive but it does the job.
