I have a sewer pipe that runs out the back of my house to the ally way. There are two cleanouts in line space about 2 feet apart and 2 fee off the house and another third clean out 20 feet out from the first two toward the alley, for a total of 3? I am pouring a patio slab that will cover the first two? Do I need to retain access to one, two, or all three...
