Due to my paranoid nature (I bought my generator), I was wondering what opinions people have on having duplicate pumps as back ups.
Some of these pumps may be hard to come by on a weeked. They are supposed to have "10 years of reliable service with no seals to leak". System up and running about 9 months.

Blueline 20 runs the skimmer circuit (not as critical).

Blueline 55 runs the closed loop.

Blueline 70 return/chiller circuit.

Should I buy duplicates? If so stick with Blueline or switch brands?
