Thanks for your reply fickell. There’s no chance of cross over. I told the service tech on the phone all the details and he insists I must have put it in backwards and recessed it too deep. the $100 reverse cartrige and $70 extension kit is all he can do for me. Needless to say I feel like Im getting the royal shaft.
I guess I’m just wondering if this is an isolated case or if others are sharing this experience. It does seem ironic that the reverse cartriges are selling like hotcakes, They’re backordered 3 weeks. Must be a lot of dyslexic plumbers out there, heh?
