After more than an hour of looking up pump info, now I still need some help. I'll start at the beginning.
Our spa jets pump, which we inherited from the last owner of the house, froze. From the label, I think it was model SP1615Z1M. It was a 2 HP Hayward Super Pump. (The labels for the new motor and the old are attached below.)
So I began looking for a new pump, and bought another 2 HP Hayward Super Pump. This is the motor:
When I got the new pump home I realized that it had 1-1/2" inlet and outlets on the housing, whereas the original had 2" inlet/outlets. And that brings me to my questions.
1. Is it OK to use the new pump with the 1-1/2" ports on the new housing? Will it cause any major performance reduction? If so, I can use the old 2" housing with the new motor. I'd prefer to use the whole new pump/housing though and redo some of the plumbing that I need to do anyway to replace a broken check valve. (FYI, we won't be using this pump all that often, so while my first priority is usually efficiency, in this case, it's not that much of a factor.)
2. Is there any other reason why the new pump is not an acceptable replacement for the old pump?
Thanks for your cold-weather pool wisdom, in advance--
