Thanks for your reply. Yes, after over a year, I finally registered and account on the forum. I was just ready to tear it apart and see where the problem is. He did not have a parts breakdown of the assembly, but is going to contact the vendor to try to obtain one for me. I don't know why they wouldn't have that info on hand. I do have a tube of plumbers silicone. I'll wait a bit, then just pull the faucet cartridges.
