Considering getting an overhead sewer installed due to basement flooding through floor drain during heavy rain storms (once a year). In any case, I'm getting estimates done for flood control valves and overhead sewer. I'm trying to save money but also want something that will last. My plumber is suggesting I go overhead sewer with clay pipe instead of cast iron, if I want to save money.
My concern is that my house is a little over 60 years old and currently has clay pipes under the house for the sewer. I was told that if I used a plug to plug the drain hole/or a stand pipe, that it will cause cause pressure in the clay pipes during a sewer backup and that may cause them to burst or cause my floor to buckle. So if I choose to go with the the overhead sewer, the stack would be cut and ran out through the side of the house and under ground where it will connect with clay pipe to the sewer line (roughly 50-60ft). Wouldn't the clay pipe still be under the same pressure and crack/burst as the same way as if I was using a plug to plug the drain hole? I know water levels itself out, but I'm thinking it's the same pressure but now it's outside the house than inside the house. What's the difference? Would it be better to use cast iron pipe then?
extra credit: what is the cost difference between 10ft of clay pipe vs iron pipe? cant seem to find this info anywhere online. Thank you.
