Personal request for Isaac.
Hello Isaac. Been watching your videos for a long time now.
Any time u post a video that is similar to a project I'm doing I turn one of your 30 minute videos into a few hours by me just pausing and going back and forth just watching how you do things precisely and accurately.
With that being said this leads me to ask you if sometime in the future could you make a video showing how to chip up a drain all the way down below the slab, properly replace the cast iron or copper p trap/drain and back fill with gravel or sand (which ever material may be on the job site you are on that day) and how to pour your concrete once you are done backfilling. Then how to install a schluter or flo f x drain for a foam pan install.
I've seen the mortar bed floating videos of yours but that's beyond my skill set at the moment .
I hope this post gets approved and Isaac sees it. I know you can't pick a job like this since being in the field you may not always have this specific set up but if you ever do I hope you use that as an opportunity to make a video showing that specific set up for us beginners.
Best wishes
