How to Install a Subslab Suction

Choose an unused corner in the home where the concrete foundation is visible, such as in a laundry room or basement.

Measure the PVC pipe's diameter with a measuring tape.

Cut a hole into the concrete with a concrete saw or drill. Make sure the hole is slightly larger than the PVC pipe's diameter so the piping can easily fit into the opening.

Push a PVC pipe down into the soil in the opening. It may be necessary to loosen the dirt with a pick if it is heavily compacted.

Cut a hole in the home's wall, near the ceiling, with a power saw. Verify that the hole is adjacent to the installed PVC pipe, and slightly larger than the pipe, for easy installation.

Cut the installed PVC pipe at the wall hole location with a power saw. Connect a fan to the cut pipe with PVC cement. Attach a PVC joint to the fan's other open end. Connect another PVC pipe to this joint and through the wall hole.

Connect a PVC joint to the pipe extending outside through the wall hole. Attach multiple PVC pipes in a vertical position, flanking the home's exterior wall, until the piping reaches the roof level.

Attach support straps along the PVC piping's length. Each strap should have a spacing of approximately 4 to 10 feet for securing the piping to the home's walls.
