The concrete where the sewage basin, closet bend and flange will go has been removed. Now, I will dig the dirt and install it all.
When it comes to securing the flange to the concrete, it will need to be secured to new concrete--since I chopped away a good chunk. Even if I didnt, I would probably chop it away so I could put new concrete there--just because the existing 60+ year old concrete is a PITA to drill into.
So, I will put the pipes in, test, and then pour new concrete.
When it comes to securing the flange to this new concrete, should I put the flange at the correct height (top of floor + depth of tile and thinset) and then put the screws into the concrete when wet? Maybe a piece of threaded rod would be better so it could be undone in the future.
Or should I let the concrete dry fully and then use molleys or tapcons?
