I just replaced the cartridge in the faucet and put everything back together, now the handle won't stay "up" when the water is running. The weight of the handle forces the water to shut off. Evidently whatever used to hold the hand upright is either loose or missing now, or perhaps I just put the handle back together incorrectly. Does anyone know why this would be happening now, and what I can do to fix it?
Many thanks,
Tim
