Installed with the moen sarai facuet to divert to a side sprayer. Works great.

If you have a kitchen sprayer that is weak (and calcium clean), suspect this valve as the culprit. The new valve resulted in a consistent strong sprayer flow.

The new 144578 is longer and wouldn't fit my 2012 faucet . I cut about 3/16" (most) of the collar off of the top / spout side and it is working fine. It would be nice is Moen would mention that.

Made our kitchen faucet work like new

My moen kitchen faucet and sprayer simply quit working. No water! Analyzing the entire system it seemed the only thing that could be failing was the diverter. It took about 5 minutes to install a new sprayer/hose and this diverter and everything is working like new. I'd buy it again!
