Have leaky goose neck, one handle Glacier Bay kitchen faucet.It's about 2yrs. Old.
I removed the handle and the cartridge #v25d(18/04/12, assume this the manufacturing date.) Can't find this part anywhere. Please Help!

If Home Depot can't help, you may be out of luck. Parts are not stocked for repairs by most other plumbing parts stores. That is why a Delta or Moen is a better choice unless it is a flip.

Yep Agree with ma0641 Home Depot is the best shot, Good luck.
