I'm having a local contractor put in a fiberglass mfg inground pool. They started with a bed of sand and seemed to be checking for level. after a bit of sand they made some adjustments with some jacks on the corners.
Now that it's about 2/3 full of water (and sand around the edge), it seems like the pool is not 100% level. I used a small torpedo level and I could see that it was not completely level (still inside the big square, but not completely center), and realize that at 15 ft, a larger level might show even greater amount off.
This is a stupid question but,
#1 - how can I best verify how far off level it is without investing lots of money?
#2 - how important is it that this type of pool be close to 100% level before they pour the concrete up to the edge and finish up?
Thanks!
