Once you do a routine cleaning of it completely at the end of the day with a tank cleaner or just clean water, you will sure it will last longer.

Do the lubrication of the o-rings and at least one time in one year. During the colder months, you need to add RV antifreeze or automotive antifreeze to prevent any damage due to cold temperatures.
