This bathroom is located on the main floor of the home and uses a single 1/2″ hole through the floor behind the toilet to route tubing and power into the basement. The toilet hides the tubing and power cord resulting in a clean looking install.
Since the area behind the toilet was directly above an HVAC return, the power cord and tubing needed to be fished a short distance through an access hole drilled through the floor joist using a 1″ spade bit. The power cord was fed into the hole first and was fished with a straightened clothes hanger wire hook through the 1″ hole. The tubing was then electrical taped to the cord and pulled through the routing hole in the bathroom floor and floor joist.
The sanitary drain pipe vent saddle was installed on the vertical pipe directly under the toilet flange since it was the easiest position to access with a portable drill.

An existing nearby lamp holder was upgraded to one with a built-in outlet for the Sniffer pump power supply.
After cutting the air exhaust tubing to length and completing the connection to the vent saddle fitting, the 1″ access hole to the HVAC return was sealed with expanding polyurethane foam gap filler.
