New pool build with busted pipe under concrete

[jenepher1202]

So I’m just looking for some clarification or insight if there are other things I should be worried about now or even down the road.

We are getting a vinyl pool installed. Around 925sq ft salt water lagoon shape with sun shelf. Last week(Friday) they came to start pump. Then muddy water started shooting through jets and coming from behind the liner(at top) all around deep end. So they tell us there is a busted pipe under concrete says they will be back out on Tuesday to assess the issue. They didn’t come yesterday but supposedly came today(Wednesday) but still havent got any kind of update. Communication with project manager has not been very good so just don’t feel confident in what he tells us. At this point all he has said we might not have to dig up concrete- my questions is
1. If they try to dig down to pipes without taking concrete up, won’t that weaken the structure of the concrete for further down the road?
2. Does this type of leak put my liner or structure of pool at risk? (Galvanized steal walls).
3. As water continues to evaporate over time, the sun shelf now has no water, is this harming the pool? Nobody has said anything?

What things should I be looking for or be making sure they do/don’t do.

We went with a very reputable company(not cheap) for this pool build but I feel like it’s been cheap service. Down to their trash being scattered all over our yard, and now even just floating in our pool. I’m just want to be educated on what this means and means in future. I’m worried that if they “bandaid” fix it but then down the road something goes wrong we will be out of warranty period. As of right now there hasn’t been any talk of what excatly the plan is or when they plan to fix this. We haven’t seen project manager in over 3weeks. Is this normal?
