I have a tub/shower combo. Just recently I noticed (it's the kids bathroom)
that only about half the water was coming out of the shower head and the
rest out of the bathtub faucet. I figured it was a diverter problem
(Waltec). I bought a new one and installed it and the problem remains. Is
there a trick to installing on of these things? I have done it before with
no problem.
