Just curious about this.
Seems like I see more and more homes in my area have the u shaped plastic
pipe coming out of their lawn.
Sure does look horrible.
Obviously, it's a vent that is over the septic tank itself, or possibly over
the leaching field.
Anyone know which ?
Years ago, you never saw these.
Is it a recent building code requirement (live in Mass.) ?
Why is it used, or required ?
What if it isn't used ?
