Removing raised floors.
With some great help from my brother-in-law nick I began removing the raised floor in the bathroom.
This turned out to be quite a task as the the water is not entirely shut off to the area. (I know bad idea but I had to get started and the 20 yr old valves wont cooperate). Reguardless the floor removal began and we did get quite a bit removed. The floor was raised by the PO to run pipes to the other half of the split bathroom, so I am dealing with a 2x4 (on end) frame for the raised floor. There were way too many nails in the plywood for me to peal the sub-floor up nicely so I am ripping 12 inch strips with the skill-saw, which is very time consuming. The frame pieces slowly came out as we removed the chunks of plywood.
Removing the majority of this raised portion of floor has enabled me to discover various interesting hack jobs that the PO did when installing this remuddle job. One of these discoveries is an original floor joist that is basically hacked in two for roughly 10 inches of its length. The current stack and hot and cold H2O feeds as I expected run through the 8x8 verticle boxin that runs in the buttler stair well area. More on removing the raised floor once I get to it again.
