Are Pump Covers Worth It?

[SoonerSailor]

Thank you.
My first pool pump lasted eight years and wasn't covered.
I recently purchased a new pump and was wondering if I had covered my pump would it have lasted longer.

The problems will be apparent if you ever have to take it apart. Rust. Once tried to pull the bearings on a pump that was probably 5 years old and was impossible. Mine is 1997 vintage, in a poolhouse, and clean as the day it was installed.
