We have a new pool (finished last June), and the way they plumbed it, the water being suctioned from the main drain/skimmers is split between our 2 pumps, one of which feeds that water through the filter before returning back to the pool, but the other pump just catches any big leaves in the pump basket and then feeds the water (unfiltered) back into the spa. This is how it works when we are in "pool mode" and our spa spillover into the pool is on. When vacuuming, we have to turn off the 2nd pump so it doesn't feed vacuumed debris back into the spa (learned that the hard way). I'm fine with the vacuuming solution, but the rest of the time it does bother me a bit that half of the water being pulled from drain/skimmers is sending small debris into the spa. The pool maintenance guy said installing an inline filter is the only way to address the issue. My question is, do you think that is worth it? I don't know what is involved with installation (are we risking him breaking something else) or maintenance (are they easy/difficult to clean). I'm trying to decide if I should just accept the plumbing the way it is, or push for our pool builder to pay for an inline filter to be installed. Any opinions/advice?
