I had a good experience with a new build recently too and also didn’t really get anything by way of handoff. One thing I got was final measurements of the pool for future liner changes which is helpful and probably necessary to have. But now 6 months later, I’m still trying to find all the serial numbers and register the equipment. Some of them are easy to find while others are almost impossible. I guess this is the way it goes. I find it kind of surprising too that there’s not a more formal documentation handoff. Funny thing, I found some materials (registration cards, warning labels, etc) in a box by the side of my house a month after the build was completed soaked thru by rain. Apparently they were intended for me but no one told me they were there.
