Sulphur smell from only one faucet

A long time sago I had an RV that had an under counter filter in the system.

That thing got rotten during the winter with pink stuff in it.

Water bug might be on to something. Could it be the drain that smells maybe from a bad air admittance valve/cheater vent? Look under the sink and see if the drain line has a stub that sticks up a bit and then is terminated with a threaded cap like this. Link.

Unscrew the vent and make sure air only flows in one direction. Or for $3 just replace it and see if the smell goes away.

Flush your hot water heater perhaps adding a little vinegar

Since the smell is only at one faucet, it may not be the faucet at all. As water runs into a drain, sewer gas is displaced. That gas typically escapes through a roof vent. If the roof vent is plugged, the sewer gas looks for the next path of least resistance. That path is the drain where the water in the the U-trap is being disturbed. If your bathroom has it's own vent, you would only notice the smell in the kitchen. It is also possible that your kitchen and bath have seperate grey tanks, again each having their own vents.

EDIT Try filling a large pan from the offending faucet. If the water in the pan doesn't smell, the problem is the drain.

I have also found this to be a problem with some Price Pfister faucets.

It is the supply lines to your faucet. You probably have the white plastic tubes with fiber brades inside. I change these out for customers all of the time.

Sulfur smell and lower flow at kitchen sink.......

Disconnect water feed lines to faucet and flush them out.
Faucet.....may have to remove/disassemble and clean out with 'CLR' or vinegar soak

No idea, but you could disconnect from city supply, try sanitizing your tank with bleach and run it thru the kitchen faucet, let the bleach water sit in the lines for awhile, rinse and run thru lines and see if that helps.
