My Emerson crapped the bed and needs to be replaced. Physical damage internally - probably not worth any repair I could have done to it, and it's rusted as all ****, so I'm sure it's as old as the house. I see a ton of pumps online, but I'm not sure how I'm supposed to judge them. I assume HP is a deciding factor, but how do I know what I'm looking for? I have a 1 HP now, should it only be replaced with a 1 HP? Ideally I'd want to connect to the same power so I don't have to rewire anything or call an electrician.
