?? Back up pumps

[SoLiD]

Blueline 70 return/chiller circuit.

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

I would recommend having a duplicate return pump only so that if you need to warrenty the pump you can just keep the newest pump as the backup. The closed loop isn't that big of a deal, but it's totally up to you.
