At my Airbnb, I noticed that the concrete is wet at the return jets. When I reviewed the camera feeds, I noticed the kids were messing around with the jets and shoving pool noodles and stuff to the jets.
I had someone inspected the jet and it all seems to be in place and no signs of damage. Is it possible that they might have damage the pipe on the inside? What are some things do I need to look for before having someone break up the concrete and go deep in? If so, what should I expect a repair like this should cost in Northern CA? Just wanted to get some ideas before filing a claim.
