Rain delayed our dig once again. So now we are scheduled for Tuesday. My husband and were looking at the items delivered and noticed the diagram on the liner box does match the pool we decided on with the builder. I sent a text but the builder says they sent the correct liner. Our pool is suppose to be a sports pool -wedged to center- 3.5’ - 5.5’ - 4’ . Steps at each end. Is anyone familiar with liner measurements /installs? Does this look like that liner to you? Should I be concerned?
