Typical
incorretly cut drain hole.
Note sloppy notch hole for
bolt receptical.
Many times this type of set
up will cause an unlevel drain. We try our best to fix unlevel drains
but many times it is beyond our control.
Its really not our job to
fix plumbing mistakes.

When
notches for bolt receptical extends past edge of drain, the showerpan
can be easily punctured. We cover holes with sheet metal but its not
as good as solid wood.
Note drain flange
sits above floor - rather than flush with floor. If we build this up
with tar it could go through the floor into the room below.
Its
actually easier to do it right.

When
the drain flange sits above the floor we have to raise the ENTIRE
shower floor. Time and material costs can be extensive.
We MAY have to charge
you extra for this work and material.
ESPECIALLY on a large shower.
Its actually
easier to do it right.
|
 |
By
the time we build up our material to compensate for the high drain AND
to raise the level of the pan above the WEEP HOLES our time and material
costs can be substantial.
Its actually
easier to do it right.
|
 |
In
addition to extra material costs, high drains create potential voids
where the drain flange meets the showerpan membrane. Low spots around
the drain can also be a problem. We can cope with these problems but
again it takes extra time and material... for no good reason since:
Its actually
easier to do it right.

Flip
BOTTOM of drain over and center it above your drain
pipe. Draw a circle around the edge.
Make sure you have one
bolt receptical at a 90° angle from the wall so the screws on the
grill will line up and look neat.
Put marks where the bolt
recepticals will need to fit.

Drill
a one inch hole just inside the circle. If you don't have a 1"
drill use something almost as big. You may have to angle the hole at
45° towards the center.

Using
your sawsall CAREFULLY cut just outside the drain outline.
A jigsaw with a sharp blade
will do this better but its not too hard to use a sawsall if you are
careful.

Notch
the other two holes.
EASY.
Be careful to avoid cutting
too far. If you do - its no big thing, we'll put some sheet metal over
the boo-boo.

Drain
will now fit snugly into the beveled hole. It doesn't have to be perfect.
It will be way better than the incorrect method at the top of this page.
Always replace top and bolts
to keep drain holes free of debris.

So
you know:
We put our hot tar membrane
between the top and bottom and then we bolt the top down so it CAN'T
LEAK. Just like the head on an engine and just as important.
Drains are the most likely
source of leaks for beginners and inexperienced showepanners.

Finished
drain.
NO VOIDS under the showerpan
at the lip of the flange. We try to make sure to set the top so the
grill screws at the top are at a 90° angle to the walls.
If you forget to get one
of the bolt holes at a 90° angle we can't get this right. Its a
small thing but customers do notice it.
