In the new house I bought, the floor drain is actually in the finished basement area. There are two doors off of the finished basement. One goes to the utility room with the well pump, water heater, water softener, and 2 furnaces. The other room contains the sump crock and the sanitary crock. There was a 6' non-bearing wall between the utility room and crock room which I tore down.

The previous owner had routed the condensate and water softener drain/overflow lines across the utility side floor using 4 different poly lines, which then went through the (now removed) wall and into the sanitary crock. It frankly, looks like crap to me having all those lines across the middle of the floor.

There's about 10" at a minimum between the fixtures (well tank, water heater, furnace, etc) and the basement wall. Plenty of room to run a PVC drain around the exterior perimeter to the sanitary crock so I can get rid of all the drain hoses on the floor and reclaim that space.

If I'm doing my math right I need to come up roughly 13" over the whole run to make the 1/4" per foot pitch. This leaves me plenty of room to install 3" bell reducers to make funnels and run the lines from the fixtures (with mandatory air gaps) and still have more than a few inches to spare.

The sanitary crock has a new 1/2HP submersible pump with a float switch that is rated at 3600GPH/60GPM @ 10' head. As they previously ran these lines into the crock without any issue I have no reason to believe it will run into a capacity issue on that end of things.

Before I undertake this project I thought I should get the opinion of some professionals to make sure I'm not overlooking something, undersizing the pipe, etc.

Please see the attached PDF with my intended plan and let me know if you guys think this will work or if I need to modify my plans a bit, or if I'm flat out insane and this is just going to be a problem for one reason or another...
