I have a tub, two sinks, a toilet, on the 2nd floor. They are the only
fixtures that drain into a Cast Iron Stack which is now clogged. This
drain line leads to a shallow 30" crawlspace with a dirt floor and very
difficult access (must crawl 25 feet to get to it). The drain runs
vertically along the short foundation wall, then heads horizonally
through the wall, just below the ground. Basically, the only piping
accessible from the crawlspace is a cast-iron 90.

The problem: There is no cleanout to get a snake into.

I would like to add a cast-iron cleanout just outside the foundation
wall, since the drain line is only a few inches deep right there. I
will snap the drain line, and add a cast Iron cleanout with the propper
no hub connectors.

Does this sound like a reasonable course of action? Is there another
way I should go? I have only worked with Cast Iron a few times before.
I figure two snap-cuts, two no-hub connectors, and I have a cleanout.



Thanks for your assistance. I did try to snake from the roof, but the
snake did not make it very far before I hit an obstruction...Of course
I snaked around like crazy with no luck. Strangely, the head of the
snake had dirt (not mud) on it when I pulled it back out. Also, the
vent is not lined up with the toilet which is not lined up with the
main drain (seems strange, perhaps I am incorrect, though it is quite
an old house with some additions). I decided that I wanted to add a
cleanout anyway, so I did not try pulling the toilet.

Since the time that you both posted, I already added a cleanout (thanks
for advice on getting a double clean-out) and I cleared the clog. Now,
there is another problem, but at least I know the main drain is clear.


New Problem:

All of the 2nd floor fixtures are draining fine, except for the tub.
When water is drained from the tub, or someone takes a shower, water
comes out from under the toilet! (FYI the toilet is adjacent to the
tub). And in the crawlspace, I can see water pouring down the OUTSIDE
of the soil stack! I plan on snaking the tub tomorrow, but what do you
think is going on? I reset the toilet only a month ago, perhaps the
"wax ring" clogged an inlet coming from the tub. Or may the tub trap
is just rotted out.

Please let me know your thoughts, and if there is anything I should do
besides snaking the tub tomorrow. Thanks!

Hi,
Wonder if tub drain vent is blocked?
