Depending where you are most homes have sewer vents. I have used this repeatedly in the US and in Germany. This is a PVC pipe going through the roof and normally well sealed by the roofer, but open on the top. In the past Radio Shack had pipe to pipe clamps the pair for less than $10. You choose the pipe closest to your GPS location and drill a hole in the pipe inside the house, above the highest toilet and bring the cable into the house. Seal it with RTV to prevent odor. Water or sewer will never rise to that level, it would overflow the toilet if stopped up. This way you have a solid set up, the pipe you connect to the sewer vent can be long enough to clear the roof! Worked for me.
