With the old drain removed from the concrete slab I have a 1 ' diameter hole and an 18" x 6" trench leading back to the drainpipe. It's about a foot deep, half concrete slab and half dirt below it. I have all the plumbing I need to put it back together but I have a few questions;
- Once the plumbing is reinstalled, do I fill the hole with concrete or should I backfill with dirt up to the slab level and then fill with concrete?
- Do I use concrete patch or just regular concrete to prevent the repair spot from settling or cracking?
- I had to cut out some plastic sheeting between the slab and dirt during removal, do I just set new sheeting in the bottom of the hole and make sure it overlaps the existing sheeting around the edge of the hole before I pour the concrete or do I need to somehow attach it to the existing sheeting?
- Do I set the bottom piece of the shower drain flange so the top of it is level with the slab or so the bottom of the lip is level with the top of the slab?
