A water tank in a motorhome can be a literal breeding ground for bacteria, which is why it is important to take the proper care and attention in cleaning it regularly. It is always obvious that the tank needs cleaning when the water starts to have a funny smell, but that smell is really a sign that you have waited too long. Proper maintenance of a water tank requires regular cleaning, otherwise, you could be putting yourself and your family's health at risk. Relying on the smell of your water is not a secure method of monitoring the cleanliness of your water tanks, and it is important to uphold a regular schedule based on how often you are using your motorhome's facilities.
How Often Do I Need to Clean My Motorhome's Water Tanks?
There are two types of water tanks in a Motorhome, and they each require a different frequency of cleaning.
Drinking water tanks need to be cleaned more often, and it is more crucial to ensure their cleanliness as they are the source of the water that your family actually ingests, and therefore is the most likely to affect their health.
Grey water tanks do not need to be cleaned as often as drinking water tanks, but it is still important to make sure they are cleaned out in order to avoid horrible smells and deterioration of your equipment.
The following are some basic recommendations on the frequency and approach to cleaning required for each type of water tank:
Drinking Water Tanks
The more often that a drinking water tank is used, the less often it will require disinfecting. The real danger with drinking water tanks happens when the water is allowed to stand due to inactivity, and the temperature reaches anywhere around 18-20 degrees. These are the right conditions for bacteria to grow, and could potentially cause issues. To avoid any potential problems, it is best to clean out the tank after even 1-2 weeks of inactivity. If it has been just a short period of time, draining the tank and flushing it with water will probably be sufficient. If the water tank has been inactive for 3 or more weeks, it is recommended to use a cleaning agent such as bleach. Proper care should be taken to use the right ratio of bleach to water depending on the size of the tank and the intensity of the clean. Make sure to flush the tank fully before refilling with drinking water.
Grey Water Tanks
In contrast to drinking water tanks, the more often a grey water tank is used, the more often it needs to be cleaned. This reason for this is obvious. I will spare you the gory details, but if you want to avoid a terrible odour, it is recommended to clean out your grey water tanks every 6-8 weeks for light use, and every 2-4 weeks for heavier use.
