I recently bought a new replacement Delta shower lever handle (#H715) for my Monitor shower 1300/1400 series. When I push the lever onto the cartridge stem the handle faces 6 o'clock instead of the customary 3 o'clock position.
There's a thick washer inside the handle that grips the cartridge stem and I'm thinking if I can rotate the washer, the lever will adjust to the correct position.
How do I either rotate the washer inside the lever or remove it so I can put it on the cartridge stem and then push the lever onto it?
I've attached a few pictures of the new lever handle and washer.
