I feel really stupid having to admit this because it's been almost a year since the pool has been completed, but my husband and I just realized that we're missing a return. We're supposed to have six, but we only have five. I remember during the construction process, my husband mentioned to me that he counted six - this was sometime before plaster, but after that, we never looked back. It wasn't until about three weeks ago, I was counting the returns and I only counted five. Again, my husband confirmed, that it is now only five. He said he knows there is only one thing that could have happened to the return... it got covered up. My questions are, when would it have gotten covered up - shotcrete or plaster? Obviously my pool is doing okay right now, but will it be okay in the future? Do we pay for each return as part of our build (if so, I'd like to rectify this)?
