    Plumbing Cuts Causing Structural Sag

    I thought LVL because of some comments I have read as I have web searched on this problem. After I posted here, I checked to see the cost of 16' LVL. I noticed that LVLs are a bit shorter than 10", 12" etc. I think the PVC pipe would be 3.5 inches outside diameter so I figured it wouldn't...
