Wire ring that holds rubber seal on next 100 washer has come off

Loosen the screw (mine has one) and slip it over the hump and into the groove. Don't overtighten. IF all you have is a spring, slip the top of the ring over and into the groove and slowly work the remainder over and down by holding the spring part apart until you get the ring clamp as far over as possible. If you have some silicone spray, this will help.
