Water is propelled via a water pump which is the heart of the RV water system. Some manufacturers also add heating elements and other upgrades to plumbing and RV water system.2
The water is then flushed to the grey water tank or is directly disposed of by draining.

- Water Tanks – There are three different types of water tanks on any RV. Fresh water, grey water, and black water tanks, all of which act as reservoirs.
- Piping – Pipes and hoses transmit water from the tanks to different faucets and taps.

Standard RV Water System Schematic
This simple illustration shows how the standard plumbing of an RV is laid out. It gives you a basic idea of what is involved in RV plumbing and a pictorial description of its functioning.
Due to differences in design and other features, only a schematic and not the exact blueprint is shown, as it differs depending on the RV manufacturer, the floor design, and other aspects.

One can also distinguish that this plumbing schematic shows the bypass and its usual location. Not all RVs come equipped with this but if you’re going for Forest River RV, it is likely to come equipped with one.
You can also learn from this diagram where to add the RV anti-freeze when required. After looking at this illustration, diagnosis, troubleshooting, and repairs of the RV water system shouldn’t be a problem.

This simple diagram sheds some light on the basic scheme of your Forest River RV toilet plumbing layout.

Although it is not so simple and straightforward in actuality, the basic idea is the same. It is important to note that the black water tank is in close vicinity of the flush system located away from the freshwater tank.
The tap and shower faucets are connected to the greywater tank and empty into the black water tank. If your RV has 2 toilets or additional options, like a cassette toilet, this diagram is going to differ slightly, due to additional piping and other components.
