I was able to stop a leak that had been increasing in volume for months, and it took me less than an hour from start to finish. Now I have no leak at all, as you can see from the photo, it`s bone dry as soon as the water is shut off.
If you're DIY plumber--like me--it really helps watching the Youtube video on this installation before diving into the repair. Otherwise, everything fit together just fine. Definitely have some silicon grease on hand. If you don't have one of those slick flat-jawed channel-lock pliers, a big adjustable Crescent wrench works well. And, if not rushed, take your time.
As for this repair kit, same part number, it was the only one on the shelf, and included all the pieces shown in the picture, PLUS the ball. That was nice. The shock was the price, as apparently it included the ball. Oh well, the faucet is fixed and the Mrs. is happy, which is well worth $10 more.
Only the washers fit my delta bathroom faucet . The other parts were for a different faucet. I thought these were universal and they cost my 2x the price of just the washers. Didn't realize this until I had everything apart. Now need to get other parts to complete the fix.
