I have a Pentair Mastertemp 250 that is now entering it's 4th pool season. I went out last night to find the service light on and water leaking from underneath. I'm trying to find what the warranty is on it but all I can find is referencing some card I don't have. Does anyone have any idea what the warranty is on these? I will make a difference who I call for service. I included a picture just in case someone can suggest something else I should check. Thanks.
