Anything wrong with this vent stack?
Slows the rodents down LOL
Especially when this is what was under the stack. :mrgreen:
It also slowed the plumbing down.
I always grab the stacks and in this case, there was no pipe present. Not even a hole in the decking. This was above an un-permitted recently installed bathroom on a flipper home.
A blocked stack such as in the picture will cause issues such as gurgling in the drain and slow them down.
There must be enough air to displace the same volume of water so in some cases such as a building where a few people are using them at once this can be a bigger issue.
Cover your vent stack and see what happens.
The bigger issue is that there was no vent stack…at all! :mrgreen:
