Is long waste pipe OK for food waste disposer?
With 1/4" per foot (a normal drain line) you should be fine. If the pipe is totally horizontal it may not work well over time as oils , grease soap scum and just normal organic matter will cause backups. 10' with the drop from the disposal may not be a problem even if close to horizontal. Make sure to run water for a little while after the disposal is clear to flush the material down the drain. If greasy stuff use Hot water and you will probably be fine.
