I bought a house that is filled with Delta products and has these in every bathroom. I have been liivng with weaker pressure in the master than other bathrooms and have tried to figure out why and suspected the shower head but have been liivng with it as I have two heads in that shower. But I just went to clean another shower in anticipation of a guest and when I turned the shower on it was gushing water from behind the head which brought me to this website to see if it could be fixed. And I see that I am not alone and that the answer is no. Disappointing.
