Shower/tub overflow drain + tar

[ic0n]

Hi forums I am replacing my old tub with a new one and the drain distance is different so I have to change the overflow drain. What is a easy way to remove the black tar around the drain pipe? TIA

So I used some rubbing alcohol and soak the tar to make it soft. I finally got it all out now my question is what should I fill the hole with after I install my overflow drain?

New overflow pipe did not aligned with bathtub. I had to cut the overflow pipe and install a flex pipe, will this be ok? Should I just fill the hole back with tar or concrete?

You likely dont need to fill it. Sand if anything.

Thanks John. I was going to fill it with gravel then top off with thin layer of mortar. Sand it is.

Next question is are my rough in valve and drop ear depth looks ok?

and drop ear depth looks ok?

Depth looks good to me.
Once you get an ok on that, you are going to add another screw or two I presume.

Thanks Reach4. Yes I am just dry fitting everything first. Next I will be laying a 2" bed of mortar to set the tub. Also is it a good idea to put a piece of plastic bag between the mortar and tub?

I am bothered by the word "bed". Search this forum for mortar piles.
You don't want anything similar to a flat bed.

Mortar dollops, I would picture about twice the diameter of the gap, can go in plastic bags, or yes, you can put plastic under and/or over. You want the mortar to squish, and you want to have space for it to spread out while squishing. Mortar does not need air to harden, and it is better if it does not dry out soon.
