return pump not performing

[mark]

for a 90 on the inlet read different places 3-5 times pipe diameter for minimum length of straight piece between pump and elbow.

seen also in Red Dragon manual here, pictures and everything

saw that, threw on a straight pipe -minimal difference (but better)

just trying to see if the previous owner has put on a different pump head. right now I have a 1-1/4 inlet and a 3/4" outlet (I thought I was reducing it, but i'm not)

I thought I had found somewhere that it was a 1" outlet

I talked to the previous owner, great guy, he suggested it might not be performing because someone had run it dry for a couple minutes, and offered a full refund.
