How long the water in your motorhome tank will last depends on the quality of the water you fill it with. Other factors include water temperature, cleanliness of the drinking water tank as well as the piping system and, of course, the use of preservatives such as silver nets. They all affect longevity. This is how long water usually lasts:
- 1 Week– If clean drinking water from the tap is put into a clean fresh water tank, it will keep for about a week.
- 1 Month– Clean drinking water that has flowed through a fine-pored filter into the clean fresh water tank or has been specially disinfected stays fresh for up to a month.
- 1 Year– With preservatives based on silver ions, the water can be kept for a year or more.
Over time, stored water can go bad, no matter how clean the tank is. The reason is microorganisms such as bacteria and fungi, which are inevitably present in the water, as well as biofilms in the tank and pipes. Stagnant water in the water tank offers ideal conditions for bacteria and the like to multiply. Luckily, there are ways and means to counteract the growth of germs in the fresh water tank and also to conserve the water for a longer period of time.
