Hi all -
We bought a house with a pool that needs some serious help, since the previous owner didn't open it in over 9 years.
While My childhood home had a pool, this configuration is quite different than what Im used to. For some reason, it seems this pool filter has two pumps. One of the pumps connects to the multiport and filter tank as usual. The other pump seems to have two 1" ID (or thereabout) hoses, which I imagine connect to the 1" barbs in this photo.
One side appears to Tee into the filter inlet or outlet, but the other side goes into the ground. Any idea where this goes? I should also note that there is some kind of automatic vacuum system in my shed, which may have something to do with the second pump, however I dont know where it would attach.
Also, there is a small multiport (not pictured) that feeds the primary pump before the filter. Does this select between skimmer 1 and skimmer 2? Or more likely, does it select between the skimmers and the main drain?
