Stormwater pit number 2 installation 

Very helpful. I was looking for something exactly like this, but this person forgot to show the hole.

The snap T's usually have grooves to run a couple of hose clamps either side which alleviates that one concern you had.

Did you cut a hole in the pipe that was in the ground?

Please do not glue the Sched 40 drain pipe to the top grate unless there are screws holding the grate so you can remove it for cleaning.

Haha asks the dog what he thinks of the job- Ruff ahahaha what will happen to the didgy joint = Woof ahahaha
