Call him on it. That is wrong. The pipes should be under the rebar.Seems to me someone tried to do it cheaper, be it the PB or the plumber. You don't want the possibility of the shell cracking like an egg due the thinned gunite where the pipes are and you want the steel encased properly and as intended.

There should also only be 1 pipe to each drain set. Deep heat is plumbed at the pad. There is no need for two pipes unless you planned on drawing water and sending heated water through two separate drain sets simultaneously (highly doubted). Each drain set should be tied at the pool bottom, not a separate line for each sump.

I think the pipes are under the rebar, but it sounds like the steel is laying on top of them and they are not buried in dirt.

In my area, what the original poster describes is not common, and I would see the reason to be concerned. It will displace the unit floor and leave a rather large void.

I missed seeing the line about the pipes under the steel. The pipes should, IMHO, have been, at the very least pretty, much buried in the gravel. The steel, to be supportive, needs to be encased and the floor thickness not be compromised.

Scott and Natural One,

Thank you for your comments and recommendations. I will bring it up with my pb. Hopefully he is intending to bury it before gunite, but I will insist on it.
