In terms of durability, the lifespan of a macerator pump depends on how much it's used. More recent macerator pumps can last up to 15 years when used sparingly, while those used regularly may need replacing after 10 years. A macerator used daily – in your home, for example – should last for around 10 years.

It's true, handling and dumping waste from your RV can be a smelly, messy job, especially when using the standing 3″ sewer hose or “stinky slinky.” A macerator can alleviate some of those concerns. Because of the smaller diameter hose, there is less smell permeating the air around your RV as waste is disposed of.

The strengths of a macerator pump is it transfer sewage over distance and elevation. The shortcomings are it likes water, needs voltage, not as fast as a slinky and less likely to purge your black tank as effectively as the slinky due to the slower withdrawal rate. Lastly, if it jams or malfunctions, it's not fun.
