I've been hesitant to post about this b/c I am getting an in-floor cleaner which I know a lot of people on here don't like but I've had the subs here like 3 times and I'm still not happy with how the pipes are buried so I'm wondering if I should keep pushing or if I should chill out...the installation guide for the cleaner says there should be 2 inches of dirt above the pipes and then it is my understanding that there would be 3 inches of gunite under the rebar and 3 inches above. The way the pipes are now this is not possible. In some spots there is only 1 1/2 inches of clearance between the pipe and rebar so either the rebar has to go up 3 1/2 inches and I lose water depth or the pipes need to go down...which is what I said I wanted but I'm struggling to get them to do. So my question is, how much dirt, if any, do I really need over the pipes?
