We have a broken pipe where the black outline is in the picture. (Verified w/leak detection service) - I've gotten a quote for $2200 from the pool company but can't get them to say "when" they will come. They just say, "We will get to you." I'm not that handy but I have adult sons that are. Is this a project we could do ourselves or is it just too big? It's not a big area of concrete as you can see - the pool guy said they would bust it up by hand, cart away the concrete, dig and fix the pipes, pour new concrete. Doable or just too hard/dangerous?
