I am changing my faucet handles out and upon reconnecting everything I noticed that the supply line washers are completely shot and are leaking badly. What is my best move here? I would like to just change out the supply lines but I don't see a nut to remove them from the valve. Are these hard to change out? Replacing the valves is out of the question because my HOA is such a pain and shutting off the main water would be a nightmare. Can I find the washers for the faucet end anywhere? If I could simply replace those it would make my life very easy but when I look up supply lines I dont even see these types being used anymore. Are these copper? Do they have a name. All I see is rubber braided supply lines. Looking for suggestions please...
