Initial plumbing..

We have completed part of the rough in plumbing process. Since we need to cement in the tank access we needed to consider our plumbing needs. One wall of the bathroom is directly above this area which we will be pouring our concrete in. So we needed to install everything that a toilet and a bidet would require on that side of the bathroom. We also needed to consider the kitchen area because we would have had to drill through a steel post to get the water there. So that isn't a good option and we are left to pass it through the concrete. No big issue, since we haven't poured this concrete yet.

One creative thing I did come up with is how to run the hot water in the concrete. Normally it would needlessly heat the concrete and take extra long before I got hot water. However I devised a system whereby I would put the CPVC inside the foam insulation and then put that within some black ABS plastic pipe to prevent damage to the foam in the concrete. This way the water wouldn't need to warm up the concrete before it got to the other end and be warm. This is a particular problem in europe with their brick homes. By the time the warm water reaches you, you've used a bunch of water for no reason.

Pipe within a pipe. This is a solution I came up with to prevent the pipe from taking too long to heat up when I run hot water through concrete. Otherwise I would be needlessly just heating the concrete and waiting forever.
