The primary advantage of installing macerator pumps is convenience. If you're installing a new bathroom in a basement and there's no existing sewage outlet, you have 2 choices. You can either install a macerator or undergo more serious remodelling and extend the existing sewage outlet down into the basement. Extending the sewage system will be costly and troublesome while installing a macerator pump is cheaper and a lot easier. Even if there is a sewage outlet in your below ground bathroom, you might find that it's not enough to effectively clear the toilet. In such cases, macerators give you an easier method to make sure that your toilet flushes smoothly, each time.
