We have a sanitary manhole with a pipe entering from a building 4 meters above the bottom of the manhole . Is this acceptable?

Hi Gratta

Sure... why not? What is your concern here?

Yes it is. What's your concerns? We maintain a slope of 1/8th" to the foot from the building to the street raiser at the curb, We then 45 down to pick up the city sewer. Again, what's your concern? Let me know, Tom
