Thank you Carlos for the quick response. I followed up on your suggestion and looked at the back of the pump where the electrical cord is coming out from. What I see there is the company logo with the name 'Octopus' printed across. Right under that, I see 'Made in China'. Does that mean I have to go to China to find my model? :-)
In any case, I hope you don't suggest me to look at the bottom of the pump since that is inaccessible unless I start unhooking the pump from the plumbing, which I'm not prepared to do now. Is there any other way to make the determination.
By the way, I think I found what may be the model of the Skimmer itself. I would think there would be a standard pump packaged with that Skimmer. Hope that helps.
