balance the damage cost caused by leak vs the cost of sump.

aroundf here tanks usually last over 10 years so i replace them at 9
years or so
ON MY SCHEDULE.

This avoids snowstorms, frigid temps, holidays and leaving on vacation.

With a nice 50 gallon tank under 500 bucks the cost of tank is under 50
bucks a year or less than a dollar a week.

sometimes it pays to replace before failure, cause its jjust easier
that way
