cut into the two inch, leave the 3 inch alone.
Made a mistake , though it was 3 inch he was fooling with...
Everyone is saying that is 4 inch and a 3 inch tee with a
clenaout correct???..
I know it is wrong,
but it looks like that has been in the ground for a long time
and has been working fine for decades..........
that cleanout was probably put in the line years ago
becasue they probably had to water test that line and had
to put a test plug into that tee....
they they abandoned it underground...
you can always cut the whole thing out if you so wish,
but you will end up having to cut that cast iron back another 5 inches or
so to get a wye into the place where that the tee is in now....
that could get real, real mean....
and its been working fine for years and years....
god gave you that 3 inch clean out for a reason...
now you figure you what you ought to do.........
