Did my pressure tank in '08, 4 years after it killed my first pump. It's a wonder the pump still works. I'd better shut up now ... and knock on wood!
It's already forming cancer spots in the paint ....
The original tank was a very small Well-X-Trol, which is about the best you can get. I replaced it with a Lowe's special (can't even remember the name ...) because it was cheap,and double the size. Almost 5 years to the day and still going.
I have my pressures set at 28/68 to extend the pump life. Those damn things are pricey .... and when they fail in January with 2 feet of snow on the ground, REAL REAL REAL
damn expensive when someone does it for you!
