Hello out there! I recently repaired a Delta single handled kitchen faucet. Washers, springs, o-rings, cam washers etc. Problem is it works for a few hours and then starts leaking out of the spout. Real bad! I have taken it apart and reseated everything with the same result. What baffles me is that if everything was not seated right to begin with it would start leaking right away but it takes a while. Any thoughts?
