I would like to know how to repair the seals inside the pumps. My problem is, that once I place my motor in the up position, it will slowly go down without using the switch. There are know signs of leaking, but appears to losing pressure inside cylinder. I know there are O rings, but don't know where they are, or how to replace them. Would you please give me help with this problem. My email is DocSkates@aol.com
