I just opened my pool in my new house for the first time a couple weeks ago. After dealing with various water chemistry problems, I've been able to get things looking great. My new problem is with an air leak in my pump. I noticed that when I turned off my pump, water would go back through the system and come out of the skimmer.
After reading some threads, I determined there must be an air leak and suspected it was in my pump, probably something wrong with the o-ring. I opened the pump casing to find that there's...no o-ring there at all, but I do see grooves where I expect an o-ring belongs. So I need to get a new one, but I don't have the old o-ring to compare it to and I'm not sure what to get.
My question - can I just go to the hardware store and get an o-ring that I think will fit and try it or do I need to find an o-ring that's specific to my pump? I don't know much about the pump and sadly don't have any documentation on it other than a sticker on it that said the brand on model number (see signature). The lid on the pump casing is also square with rounded edges, so I didn't know if that made a difference.
Thanks for the help. I'm sorry I don't have more information.
