This radon fan has stopped working. |
 |
A drain hole is installed below the fan to allow the condensation to drain back into the suction holes. This keeps the drain tubing under a negative pressure so that no radon laden air escapes.
New installations we drain condensation to the outside using a Tee
fitting |
| Dilts by-pass Drain |
|
This is a Dilts by pass drain. A moon shaped piece of aluminum is caulked into the bottom of the elbow and a brass fitting is installed for the drain tube |
|
It's a good idea to make sure there is still power to
the fan and that the power is off. |
|
Cut a half moon piece of aluminum and then notch the edge. |
 |
Fold each notch in opposite directions. Dry fit the piece inside a PVC elbow to make sure it will fit |
 |
|
Drill the inside bottom of the upper portion of the
elbow above the fan with a 1/2" bit. |
|
|
|
Thread a 1/4" by 3/8" thread brass fitting into the drilled hole. |
 |
Put a fat bead of caulk on the notched edge. |
 |
Place
the caulked aluminum inside the elbow just below the brass fitting |
| Run vinyl tubing with pipe insulation from the upper brass fitting |
 |
down to the drain hole below the fan that was previously drilled in the pipe |
