I opened the pool a few months ago and everything was going great until last week. The strainer cover had a crack and finally blew off. As a result of this, the pump ran dry for at least 8 hours. I replaced the cover yesterday, having a hard time getting it primed and when I did there was a lot of air at the discharge and in the whole system. The strainer to pump is also leaking pretty good. I took it apart and was able to pull the impeller right off without much effort. I pressed it back on and WAS NOT able to pull it off again. I closed every thing up.... and it's still running but a lot of air in the system. When I turned it off there was so much air in the system it violently bubbled up in the skimmer.
What parts are typically ordered for this job? O-ring seals, impeller and impeller seal?
