I have a three hole single lever kitchen faucet and I believe the cartridge is bad, I cannot find the make of the faucet to figure out how to get apart. Is there a special hidden place
I'm missing

Shut off the supply to the valve and remove the cartrdige. Take it with you to Lowe's, HD or Menards to get an exact match. If they can't help you go to a plumbing supply house. If you can post a picture we may be able to identify it

Post photo of your faucet... Thank you
