I have an older home and I believe the original shower/Tub and taps. I need to replace the shower diverter which is in the wall - PULL for shower PUSH for spout. The thing is I cannot figure out how ot get into it. The crome ring on the outside just spins and apears to have not opening. The button in the middle comes off (unscrews) but the appears to be no place on the stem or beside it to lossen anything off. Any ideas? Rabby.
