Why do you need to empty holding tank in RV?
RVs have two holding tanks that need to be regularly emptied and sanitized – one for grey water and another for black water. The grey water tank collects water that is washed down the sinks and shower as well as what is used by the washing machine. The black water tank, also known as the RV’s septic system, holds anything flushed down the toilet.
