Hello y'all,
I am doing a complete remodel of the existing house and a large addition. I am cutting out the old cast pipe in the house and replacing all with PVC. I was on a septic, I have taken that out and want to use the city sewage system. What I am trying to determine is if I should use gravity or get a grinder pump. When the pipe exits out from under the slab, I have to put in a couple of 45s or a 90 and shoot to the road which is about 300' away from the house. Should I put 4" pipe into a tank with a grinder pump to 2" to the road. Or, 4 inch all the way to the road and let gravity do its thing? I am thinking the city sewage is at 5 or 6 feet in depth at the road so the grade should be right on over that distance. Any ideas / opinions are appreciated.
Thank y'all,
George
