I have 2 questions. We just bought a house with a pool and I'm trying to figure a few things out about it.
1: The pump pulls air into itself and blows air out the outlets when pulling from the pool (not from the spa). The culprit of the issue is that it looks like someone plugged the main drain. Under the grate all you can see is dirt. The only thing the pool can pull water from is the skimmer (and the vacuum cleaner like once we get a cleaner) so we are at 100% intake from the skimmer. I don't know why the main drain is plugged. My question is, what are the concerns with this (other than wear on the pump? It's something we will want to fix at some point but I would like an idea on how big of a priority it should be.
2: with that still in mind, we are wanting to upgrade to a variable speed pump (preferably pentair). The pool currently had an old single speed 230v 1.5hp Hayward. I've looked at the superflo and intelliflo. Will we have any issues upgrading to one of those pumps?
