Most RV macerator pumps can dispose of waste up to 50 meters away horizontally and up to 4 meters (or 13 feet) away vertically. The exact distance and height at which your RV macerator pump is able to dispose of waste will largely depend on it's made, model, size, and a variety of other factors. If you want to ensure that your selected RV macerator pump is able to handle waste disposal at the distances you need before purchasing, consider reading the manual in order to get the details about what the RV macerator pump is rated for in terms of distance.
