A Quick Rundown On RV Holding Tanks

Before you dive into how to replace your tanks or what to replace them with, a basic understanding of each tank and what it’s used for is crucial.  There are three type of tanks in your RV:  fresh water, black water (or waste water) and gray water.  Let’s explore each of these and why they are important to your RV happiness.

Gray Water Tanks

Gray water is the water that comes from showering, cooking and washing dishes.  Some RVs even have two gray water holding tanks.  A word of warning about your gray water.  The pipes that drain the gray water are very small, so be advised against any food particles going down the drain and causing a clog.  To get rid of gray water, you can simply use a hose and drain it into the nearest cluster of bushes.  If you are lucky enough to be connected to a sewer line, the gray water hose can be left open to drain as you are using it.

Black Water (Waste Water) Tanks

Yuck!  No one wants to think about taking care of these tanks, but they are an RV reality.  Black water or waste water is the water that comes from the toilet.  There are some requirements when it comes to emptying your waste water tank.  You need to purchase a odor tight connection to empty the tank.  There is a special hose fitting, or a valve.  These don’t come with your RV, but are easy to obtain.  If there is not a convenient dump site, there is an easier option.  There are available portable holding tanks!  They come in different sizes to allow you to find one that will work for your RV.
