Plumbing After the wall is stacked, but prior to pouring, drop the pipes into the voids of the block.  If copper is used, the copper must be sheathed to prevent corrosion.  Additionally, PVC or PEX may be set into channels routed into the block. Here we see plumbing secured with screws to scrap copper pipe that will become anchored in solid concrete after the pour. Here, all plumbing and manifolds are in the slab and out of the grid-wall. Conventional framing is used in the interior. Access Boxes: If repair access to valves or pipes is desired, protect the area from the concrete pour with a wood or Masonite box shield. Quick Tip: Be sure to securely tape the ends of all plumbing and conduit before the pour. This tape keeps debris out of the pipes during construction. Electrical In areas where code does not require conduit, you may elect (after the pour) to cut channels with an electric chain saw into the block walls and simply tuck the romex wiring into the slots. This method is fast and easy, a commonly used alternative to conduit installation.
