In our contract for our pool, we are supposed to have 3 therapy jets built into a bench on one end of our pool. I noticed that there are no openings for such items and I've mentioned it to my contractor a couple of times. He said that one of his employees likes to install them personally to ensure that they are lined up properly. Well, we have the concrete down, the pipes run along the pool, and where the bench is there are two square openings that are cut out not in the bench but along it. They appear to be returns, but I'm not positive.
Does anybody here have any pictures of what I should be looking for to ensure that this is not overlooked? This is what the bench looks like toward the back of the pool with the cutouts.
