Hi All,
I'm a plumbing neophyte having recurring blockages in two upstairs toilets that are connected to the same drain pipe and am wondering what the problem is. The toilets are about 12 feet apart and come together into another horizontal pipe with what I think is called a double elbow. That ABS horizontal pipe is about 3' long and connects to a cast iron vertical with a cast iron 90 degree elbow. Here is a diagram and some pictures:
Could the double elbow be the problem? Also, there seems to be some slope away from the toilets to the elbow, but the 3' section between that and the vertical is fairly flat. We sent a camera down to have a look and saw that when one toilet was flushed, the water ran straight through the elbow towards the other toilet. in other words, there wasn't much if any deflection provided by the elbow. The water sloshed back and forth between the two toilets until it eventually found the elbow and drained out (although there was some standing water.)
We've never had four blockages in a 9 month period before, and are wondering if it's not us but the design.
I would greatly appreciate any help and/or advice.
Thanks,
Michael
Impossible to snake if there is a problem later on.
