| Properly
sealed sump cover with radon vent pipe for sub-slab depressurization.
Note flexible coupling on vent pipe for easy disassembly for
sump servicing. |

of sealed sump component with "tee" fitting to sealed
crawlspace component, and to radon fan mounted on exterior of
building. |
View
of "tee" fitting for multiple suction points in large,
sealed crawlspace (sub-membrane depressurization system). Note
properly sealed vent pipe at suction point through roof flashing
in crawlspace membrane. |

| Spit-level
house system showing suction points in basement slab and slab
on grade. Suction points for slab on grade in split level homes
are usually drilled sideways under the slab through the foundation
wall, from the basement. |
