I have a Hayword Northstar SP4020X252NS Pump that need a Cover O-ring number 5 on the diagram, however after I ordered the part # 4664-14 I’m not sure if this is the right part because I’m not sure when the equipment was installed. I just purchased the home in May 2018 and believe it was constructed in 2007. Please let me know if I’m going to need to return this part and order part # 4664-14 instead so I don’t waste time getting the wrong part and returnig it and reordering the correct part and waiting another week. Thnak you.
Thank you for contacting Inyo. Can you post a couple pictures of your Northstar pump? We may be able to determine the age of the pump.
