Review on 🚰 Delta RP47422 Two Handle Ceramic Stem Cartridge Pair for Faucet by Keith Gonzales

It's not ideal as many older models don't have accompanying pictures (come on Delta!). But in the end I found our 10 year old Victorian kitchen model with two handles and a sprayer. Once you find the model, it's easy to get a parts list that includes the part number for the valve. This is a set of two valves and they are identical so any defective side can be replaced with any new part. If you watch YouTube to find out how to replace the valve, just one note: it's an odd valve because it doesn't use the seat disc/spring mechanism that many other models use - and many videos describe it. The good news is that I think it's even easier to replace: quarter turn valves under the sink.) 2) Open both handles fully and drain the remaining water. The handle needs to be completely removed from the nut and I promise, if you do this and you're lucky it will go down the drain or be out of sight on the kitchen floor somewhere). 4) Using medium sized pliers, loosen and remove the large nut at the base of the open wing. These nuts should only be "slightly hand tight" so they turn and loosen easily - and remember this when tightening. 5) Note the position of the valve (including the gray part) - and make a quick sketch if necessary. In order for the handle to line up in the same spot, place the new valve in the same position - don't worry, we're not talking exceptional accuracy, just good precise placement. 6) If you can't raise the entire value with your fingers (you probably can't), take your pliers, grab the metal bar and pull up. Or grab your pages if that gives you the best leverage. There may be some water left when it pops out, but nothing you can't throw your finger at. 7) Take the new valve, align it and slide it SIDE into the hole. Do not push the stem too hard as you may cause the lower disc and valve to "float" or become misaligned. You know the valve is tight enough when the large nut slips open and grips enough threads to hand tighten. 8) Finger tighten the large nut, take your pliers, just make another 1/4 turn and leave. If you turn on the water and there is a leak at the base of the handle, remove the handle and tighten the nut a little, but not too much. 9) Move both handles to the closed position, turn on the water in the house. , and try a new valve to make sure the leak is fixed. I did the same and it took about 10 minutes.
