Hello. I have a speakman shower set with one handle for H or C, and another handle to switch from tub to shower. There is very little water pressure coming to tub and nothing to shower. The water pressure from the mainline to the shower/tub valve is strong but doesn't come out. I replaced the bonnet and the ceramic valves inside. Please help?

Did you have this problem befopre you replaced the parts or just after? Where is the shut off that you used when doing this work, double check that its fully opened.

Hi, The valves were fully open and water was filling the inside bonnet. The outside line is perfectly fine. Its from the valve to out of the spouts. Thanks again

When did you first notice this problem, right after your repair work?

This problem was from before and I was told to replace the valve body which I did and did nothing. It still has no pressure and water is literally dribbling from the tub and nothing from showerhead. The water is full blast under the bonnet into the valve body
