Hello all, I'm new to the forum and new to owning a pool and was hoping to get a little advice from some experts here. I just bought a pentair 011522 whisperlo pool pump on ebay and I have a question about it. I bought it from a seller listing it as "new" and paid close to retail, and when I received the pump it looks ok, but there is some blue and purple staining on it. If I hook it up and use it that may prevent me from doing a return, so I wanted to check first to see what these stains may be from. Is it some type of sealant or are the stains a clear sign that the pump is actually used?
I have included a picture. Sorry if this isn't the proper area to post such a question, but I really do appreciate any help that anyone could provide.
