Not unless it is part of the pipe you unscrew. If it is not then they usually pull out, not always easily however. The curved dip tube will only "self clean" when a high volume device is used. These days the bathtub and washing machine are about the only two that will make it function. Also, the material disturbed by it, will either settle back to the bottom or enter the hot water piping and eventually flow to the faucets and plug up their aerator screens.
