Hi, I looked up my pump, it's a SP4010NS by Hayward and found a diagram here of all parts, http://www.poolpartsonline.com/popup...26size%3dlarge
The problem is the place that water is leaking from doesn't have a number or part... It is coming from the pipe right over the Hayward writing. It screws in and something is loose, an O ring probably needs replacing but I have no idea what to call it. Any help?
