Well I get a call from the 2nd Floor Tenant again today - " The water
is surging hot/cold (I don't get the exact behavior but get the gist of

the problem) still inside the shower" I believe the hot water gets too
hot and burns the showeree or it gets too cold one or the other.


Be helpful to know which, don't you think?

Is it just the shower, or does the tub spout
do the same thing? Which thing? Stick
your arm in for 6 minutes and find out.

I'm going to try to get over there this weekend and do that exact check
(shower vs tub facet) and ask as well. I'm going on the center diffuser
rubber back washer is cracked or broke. I'm going to replace both the
hot and cold black rubber washer and do that "drill the washer seat
inside the stem" operation too. After inspection and maintenance of
this part of the plumbing, all three stems (I think there is), I hope
this one gets closed and will update on whats found and after effects.
