Hello Plumbers...Im a homeowner redoing my bathroom and am looking for advice on moving my second floor shower drain. I am expanding my shower by 1 foot or so and want the drain in the center of my tiled shower floor, so I will move it approx 6 inchs.
I pulled out the existing drain and looks like I have no obstructions where i want to move the drain.
Do I just open up the subfloor and cut the ABS pipe before the P trap and extend the drain the 6 inchs? I guess I need to be concerned about the slope...1/4 inch more slope for this 6 inch move??
Another question...I bought a cast iron drain from Home Depot...I will hop mop (in calif, thats what most do here), I take it, the bottom 1/2 just slides over the 2 in abs pipe, and the little "dog ears" keep the drain from moving because its locked into place from the wood subfloor.....but, do i place the drain ontop of the subfllor or ontop of the preslope that i will use on the subfloor? My hot mopper will use a 1/2 preslope material that will go under the hotmop..this makes it easier to have the tar presloped.....so, bottom 1/2 of drain over or under the preslope material??
Thanks in advanced,
