Rated 4.0 out of 5 by 4 reviewers.
Rated 1.0 out of 5.0 by Seldom Shuts Off Completely Have bought two replacements for the original cartridge, and both of these started giving problems shortly after installation. The problem is: they become very difficult to completely shut off. Unless you slam the handle down hard, right in the center, the faucet will either drip or have a steady trickle. I have to constantly check that the thing is completely shut off, especially if somebody else in the family uses the kitchen faucet. Don't know whether this is a generic problem with the valves, or whether my replacements were from a bad batch. But, I'm ready to replace the whole faucet and nozzle. Lot of work and unnecessary expense. Big disappointment in this Delta product. October 1, 2014
Rated 5.0 out of 5.0 by Replacement was a cinch Had similar issues to another homeowner... valve wouldn't shut off completely without moving it around at the bottom of the "v". Tried graphite to no avail. Eventually called Delta and they sent me a replacement for free. Fixed in <10 minutes. February 14, 2015
Rated 5.0 out of 5.0 by Good quality and easy installation First time I changed the cartridge on this faucet. Decided to go with authentic Delta part, even though a couple dollars more than generic brands. Good quality part was a cinch to install; literally took just a few minutes. Very pleased with the transaction and would recommend. October 7, 2014
Rated 5.0 out of 5.0 by Decent quality The old one lasted about 6 years in a busy house . The replacement was simple to do and hopefully is around again in another 6 years. June 3, 2014
