| Shower Diverter Sorry, American Standard won't let me pull specs. from 20 years ago. A diverter simply shuts off the spout and sends water up to the shower head when you activate it. The flap HAS to be FULLY SEATED before the flow is cut off to the spout. It acts like you still have something on the seat that prevents the diverter flap from seating properly. Take the diverter out and recheck the seat. It should make no difference what position the diverter is in when you install it. Regards, Tom |
