Long story but my pool builder forgot to put in the dedicated suction cleaner line we had spec'd in. The pool has just been plastered and filled. He went through all of the piping and valving and when I asked him where the dedicated cleaner line he basically said, "oops, forgot it." After a bit of back and forth he said he can dig down next to the pool and put one in. He made it sound like no big deal. Is this okay and can it be done well? Or might it be a future trouble spot? I am concerned it will be difficult to seal there and may leak. Should I have other concerns with regard to this line? Any input would be appreciated. (I want to valve this line so I can leave the cleaner in and program my automation to open the valve to clean on a schedule as opposed to putting it in the skimmer every time I want to clean. I've got automation for everything else and the cleaner was one of the main ones I wanted).
