John Well, I finally got it apart. Drilling out that nut seems like a very long and difficult process. I then took my largest vise grips, got a hold and turned. Turn the water back on by opening the shutoff valves all the way turning counterclockwise. I then went to all of the other faucets home builder put the same in every lav.
Tools needed: Safety goggles, adjustable wrench, pliers, 8 in 1 screwdriver, bowl, towels, flashlight. The sprayer is held by another plastic nut. However, if you don't understand or get confused by instructions on paper, the video and color photos in this Instructable may help you figure things out better. Usually a basin wrench, or the proper sized open end wrench, will disconnect the spray hose. Use the installation tool provided with the faucet to tighten the mounting nut most of the way.
It has been leaking forever, and I can't remove the nut that connects the sprayer to even get at the mounting nut, because it is corroded so badly. Using a flashlight, check under the sink for leaks. Warning: After shutting off the water, turn the faucet on and verify that there is no water coming out of the faucet. Now I am having a leaking issue from my kitchen faucet but am not sure if is caused by leaky cartridge. She also stated the handle assembly was getting very difficult to turn over time. It often takes only a small movement to break the seal so you can remove the cartridge by pulling on the handle.
Tip: In step two you figured out the number of holes available in the sink for the new faucet. A special tool called a can make removing the mounting nuts easier. You can use a flat screwdriver to loosen and remove the clip. It will reveal a black plastic sleeve which you will need to twist counter-clockwise to unscrew and remove. Then you can take out the side of the house while you are at it and add a breakfast nook.
The brand of the faucet being replaced is PriceFister. Push the hose into the quick connector until the black bar on the connector makes a clicking sound Figure 21b. The sleeve is made of brass, which is easy to thread. It seems to average about 4 years before I have to replace the parts. Do not turn on the water valves yet! It doesn't really matter which way it goes on, but you should make sure the plastic is completely down and snug over the copper stem. This mounting nut would be difficult to get to with a wrench, let alone a grinder or a dremel.
In less than ideal circumstances, however, the cartridge won't budge, no matter how hard you pull -- and you begin looking for ways to gain more leverage. The purpose of this sleeve is to hold down your spout it sits on top of it. Make sure that, if not doing the job yourself, that installers are instructed to leave that stuff with you, rather than trashing it. If at any time you feel uncomfortable performing any of the steps, seek help from a friend or a professional. Note: if the supply tubes look old or you have trouble removing them, it's a good idea to replace them when you are installing the new faucet.
Once the clip is off, in the next step I will show you how to use the Moen-supplied cartridge removal tool. Yes, I thought that was so obvious I didn't even mention it, but since the faucet is being trashed, get rid of anything you need to to get at the nut. I almost threw out the box with the O-Rings inside because I didn't see them after I removed the spout! Go under the sink and line up the end of the supply line to the quick connector Figure 21a. It is difficult to see and fix by just replacing cartridge. In the box with the new cartridge you will find a white plastic piece as seen in the first photo that slips over your cartridge. I will show you step by step photos as well as my YouTube video which will help guide you through the steps I took and some of my mistakes.
I will need to open and clean the parts more regularly to maintain them, as I'm sure that will help prolong the lifespan. Pulldown faucets are similar to pullout faucets. Moen sells a tool that makes pulling cartridges easier, but sometimes you need more help than that. I know it sounds crazy but after reading this thread and having the same problem it cam to me, Duct Tape. Reattaching the faucet handle after you pull the retaining pin often gives you the leverage you need. You will access a hole to get your Allen key hex tool and be able to unscrew the long screw that holds the handle on.
This makes things much easier! The left side came off easily by hand, but the right side was frozen on there. If we had a picture of yours, we might be able to make a recommendation. Failure to verify that the water is completely off may result in damage to property or cause bodily injuries, such as scalding. If you do not need these then a sink hole cover blank plug can be installed. The brand of the replacement faucet is Moen. You can leave the blade in the holder, and you can remove it from the holder if needed. If you enjoyed this Instructable, please don't forget to rate it and give me a thumbs up on YouTube.
