I have 4'x3'x3' hole at my foundation where an outside cleanout is to be installed and a small portion of cast iron pipe replaced with PVC and Fernco type couplings.
I have to backfill the hole.
How long shall I wait after the repair to assure its all good?
What is the proper procedure for backfill?
I was going to uses fresh sand along the bottom of the pipe and about 6" above and to the sides and then just dump the old dirt in.
Thanks you for any guidance.
