The length of time that you can leave drinking water in a motorhome tank will depend on several factors, such as the temperature, the cleanliness of the tank, and the type of water you have used.
In general, it is recommended that you replace the water in your motorhome tank every 2-3 days if you are using it regularly. However, if you are not using the water frequently, or if the temperature is particularly hot, it is best to replace the water more frequently to prevent the growth of bacteria.
If you are unsure about the quality of the water in your tank, you can use a water testing kit to check for contaminants. It is also a good idea to sterilise your tank regularly to prevent the build up of bacteria and other harmful organisms.
