Hello, I have a very old Delta single handle bathroom faucet with a steady drip. My intention was to replace the seats and springs, a relatively easy job, but now I fear I might have to replace the whole thing. Ive replaced a faucet before, but this looks like quite an ordeal, and I have a few questions. According to the diagram and youtube videos, I need to remove the Adjusting Ring to get at the seats and springs. This one is made of plastic, and I cant get it to move. I know the repair kit comes with a special wrench, but I have a similar wrench that fits, and all it does is mangle the plastic. Does anyone know a special trick for getting it off? The roundish cap also needs to come off. It looks like someone else years ago tried to remove it as there are plier marks and the body of the faucet body is cracked on both sides. It does not leak from these cracks. Again, is there a good way to get this off? If not, Ill need to replace the whole thing. Heres where the fun begins. The nuts and washers under the sink are completely rusted over. I can tell just by looking that theres no way Ill get a wrench to loosen those nuts. Ill probably have to flush cut the bolts and pry the old washers off. Would a Dremel tool with a metal cutting wheel be able to do that? This is a very deep sink, and the pipe extensions under the faucet are about 6 inches long. The model faucet I want to use has lines that are only about 3 inches long. Therefore, I will have to put in new supply lines. No problem, right? Except, the supply lines have no shutoff valves! The parts are all originals, I think, and the house was built in the early or mid 60s. The parts are all threaded, but I havent tried turning them. Ideally, I would disconnect the compression fitting and install a new 12 braided line. If they are stuck, how much trouble is it to cut the pipes and install actual valves? This has been dripping for years, but I couldnt fix it since the main shutoff valve to the house was stuck open. I just had a professional replace it, so I would prefer to tackle this myself to avoid another plumbing bill. Any advice would be greatly appreciated. I would like to come up with a good plan before I go out and buy parts / start cutting.
