Terry, I had a problem with my shower-tub downstairs so I replaced the stem, ect. After I fixed the problem
I developed a problem with pressure in the same tub down stairs. I went up stairs and the pressure was great for 3 showers now the pressure upstairs and the down stairs are both non existant. I haved checked for leaks, ect, nothing. The pressure in the kitchen the lavatories are good??? I checked outside at the hoses front and back, both have good pressure. I just don't have any water or very little water going to the two baths. Help me!!
