done tile in a few rentals - few problems with cracks from shifts. just sayin

I'm sure this is somewhere - but cannot find it, so I'll do this the easy way. To the left of each thread there is a little circle with lines in it. I have figured out that if it is red, then there are posts I haven't read. But some have a little star inside, and some show the lines scrolling . . . ...

I agree with bobfather - open the hot water tank (HWT) breaker, partially drain & disconnect, and pull it out of the way to do it right. It wont take long to pull it & put it back; certainly not as long as monkeying around it

Whenever I can, I cut out the drywall to a stud and put in a regular box and outlet, then re-rock the area.

Thank you

Folks smarter than me say that green board is a ripoff - no different than regular rock. Recommend hardibacker
