I'm so sorry, I didn't mean to imply that you were wrong. I believe you. I'm just surprised that it's rated that high. I'm also surprized it's rated in horsepower and not just GPH. Compare it to a 1/2HP Hayward Superpump which is rated for 48GPM(2880GPH) into 20' head or the 1/2HP Hayward PowerFlowII which is rated for 45GPM(2640GPH) into 20' of head. It would be interesting to learn just how much head pressure is figured into System Flow Rate.

Anyway. The solar dome you have may be rated for the Intex pump market or for the traditional market. I don't know. So, to maintain compliance with the instructions, always leave the bypass link open.
