Galley Faucet
FWIW, some faucet makers guarantee their products for life. Moen is one example. In some cases the guarantee applies to only their valves and related parts. I did not know what brand we had on our boat so I sent a picture of our faucet to an online distributor. He quickly told me it was Grohe. The spout that broke during a hard freeze was not covered by their guarantee.
In the case of our high end Moen products that we have in our home, I called them, explained that our bathroom faucet was leaking and asked what I should do. They asked me to give them the ID number off of the faucet, my name and mailing address, and that they would send me two new valves, which I have since received; one for the hot side and one for the cold side, covered by their life time warranty. I had the same experience with our Moen kitchen faucet, but in the end they sent me a brand new faucet as the repair parts they sent would not fit our model that they claimed were supposed to.
Whether you have the same experience, time will tell, but it would be worth your while to take similar steps to see if you have the same or similar outcome. However, if money is not an issue, your local big box store will gladly part with your money in exchange for faucet valves.
