Thanks... I will get the hanger in there...somehow.... The exhaust
pipe you can see in the insulation will requite use of 2x4 .... by
looking at it.... butI will measure and try for a 2x6 if I can..

How do I get the new sub under the flange.. work around it with 2
pieces making up the new sub floor ....or cut the flange out and redo
the PVC?
