the hard part
the hard part of the job is to install this
drain after the shower has already been installed
from underneath
it can be pretty mean , I mean very mean----
to get the nut to tighten down
enough to the old shower base when you are standing on your
tippey --toes on a ladder trying to move a 4 inch nut
and squeeze out the acess putty ...
Remember -if you dont squeeze out most of the putty it will
not tighten down properly and the flange will loosen up over time
normally this is done on the rough inn
with a large 24 inch Rigid wrench
which you cant use in this situatioin...
probably a hammer and small chisel to tap the nut and
tighten it into place...will work best...
usually it takes someone upstairs standing on the flange
to keep it from moveing on you (your wife)
--------------------------------------------------
Now,
I know I am gonna get some rave comments from my astute
audiance on this advice ...but here goes anyway...
In a few of my more mean situations, I opted to use clear
water proof silicone instead of putty on the lip of that
flange.....if everything is clean and dry it works great
a very healthy amount works best , cause it all wipes off.
it squeezes out good, the nut tightens down great
all the way down to the base without the usual troubles like with putty.
and
it makes a %100 water proof seal to both the lip on the shower base and it also makes almost a PERNAMENT seal on the bottom side of the
base around the nut and gasket . Just clean it up with your finger
on both the top and bottom...,.
Note.....the only down side I have ever found about doing this is
it will never unthread off again....without a hammer and chisel..
its on there to stay.....
but you were not planning on doing this over again, right??.
now on the top with the no-caluk clamping down ring,
I suggest after you clamp that neopreme ring down tight to the
pvc pipe , you also put a bead of silicone on top of all that
for extra measure and give it slope into
the drian .........that I do on every job for my own
satisfactioin
then you absolutely know it is %100 water tight on that second
floor shower
support it with bailing wire or something
if you need to after you are done ,
thats all secondary--- any kind of glue that is compatabel with
the brand of plastic pipe you are useing will work,,,
just be sure to get the drain tight,
or you will do it again some day.
have lots of fun......
