Hello everyone. I'm new to this hobby, so this site and everyone's posts are a goldmine. I have a problem with the placement of my sump return pump. The previous owner placed the sump return pump 2 feet behind the entire unit. This won't work, as I'm placing the system against the wall. So, I have only two options. The first, I can elevate the pump slightly above the sump, making sure to fill the hose lines with water before starting the pump. Is this a good idea? Or I could place the pump in the sump. The only problem with the second option is that I can't find any information on whether my pump is submersible or not. It is a pan world px 100. I'd rather elevate the pump if it's possible, that way I don't have to plug the existing hole in the acrylic. Again, I'm totally green when it comes to this hobby, and plumbing in particular. Thanks in advance for your help!
