Hello all several questions are some pumps more quiet than others. If so I'm sure I have a loud one OM gosh is that loud. It has been lubricated and still seems loud to me. Hopefully when the doors are installed this will take some of it away if it doesn't maybe you all can suggest a better pump to purchase. Also has anyone ever encountered them over heating still new to this all hope to upload a picture later. Good night from the East Coast all
