What is the fresh water tank?
The fresh water tank on a motorhome is a container designed to hold clean, potable water for various purposes such as drinking, cooking, cleaning, and showering while traveling. It's an essential component of the motorhome's plumbing system, providing a convenient and self-sufficient water source for occupants during their journeys. Depending on the size and design of the motorhome, the fresh water tank can vary in capacity, typically ranging from around 20 to 120 gallons or more. These tanks are often made of plastic or other durable materials to withstand the rigors of travel and varying environmental conditions. Access to the water in the tank is typically facilitated by a water pump and a series of pipes that distribute water throughout the motorhome.
