Shower to tub knob (possible bad install)
Excuse the lack of proper terms. I am an excellect electrician, but stink at plumbing.
About a month ago, I replaced all three knobs in my bathtub / shower.
I had a drip, but while trying to replace the washers, I tore up all the sleeves so bad that I just bought an entire replacement kit, and replaced the stems for all three knobs.
My left and right knobs are for hot and cold water. The center knob diverts the water for either shower or tub. I replaced this carterage as well.
All worked fine for several weeks. Now the center knob will not divert the water to either the shower of tub with any force.
Before I tear the plumbing apart again, does anyone have any suggestions for what I may have done wrong?
