Quick question for any experts here. PB installed my liner and it looks like it's not tucked in all the way in the corner by the steps. The corner seem is about 2-3" away from the actual corner and there's a void behind it. I attached a drawing to show what it looks like as it's too hard to take a pic. Also one of the lights seems to have a very small leak as there a small puddle right under it. He says it's nothing to worry about and he'll take a look at it when he comes Thursday to back fill and correct it if necessary. But I'm worried with the liner as it seems he's pushing that it's nothing to worry about.
Here's my original thread of the pool build. Have to admit they did a great job under the circumstances.
