Perfect parts, lack of proper instructions.
Part works great, once you figure out the proper orientation of the spring, plastic cup, cartridge and handle. When I pulled off the handle and cartridge, the spring and cup came out of place, so I had no idea regarding the proper placement and orientation of these. Trial and error, and 1/2 hour later, I figured out that the spring goes in the hole first, then the cup goes over the spring, cup side down. Then the cartridge needs to go with the tab oriented to that the handle will fit over it. Also, as you're tightening the big nut, the cartridge can shift upward and out of the slots, which allows it to turn. So you may need to take a small tool to push down on the cartridge (not the stem) while you're tightening down the nut. A simple picture of this would have made the job simple.

Just What I Needed
I had a faucet that would not shut water off to the spout. I went to Home Depot to get a replacement part and installed it and the faucet still ran. I sent away for the"official" part from Delta and the problem was fixed. I can't tell any difference between the HD part and the Delta part. The Delta part is more expensive but then it worked. I'll be more skeptical of repair parts HD. The Delta package contained two sets so that makes the individual unit price not so bad.

Hello, when I turn the handle on my faucet the handle goes beyond the stop point after it is shut off. What needs to be replaced the stem unit assembly or the handle assembly? I have the Valdosta 35757 LF-SP two handle widespread Bathroom Faucet.

Both handles are loose, how do I tighten them up??
Hello don108!
Thank you for your question and we are happy to help! We recommend removing the set screw from under the handle with a 1-8th allen wrench. You will then want to tighten up the bonnet nut below the handle. If this does not solve the issue, we recommend replacing the bonnet nut and set screws that are specific to your handles.
With any further questions or concerns, please do not hesitate to reach out to us directly.
Best Regards,
Carrie

Location of the white ring please
Hi dave,
Thank you for your question about the Delta Faucet RP74418. The orientation of the stem may depend on the faucet and the handle type. I recommend noting the stem position before replacing it. The stops should likely point toward the spout.
This is a manual for one faucet that uses this stem.
