belly in sewer line
We have lived in our house for 10 years. The house is 21 years old. We are getting ready to sell it and a sewer scope found a 6' belly in the line about 30' from the house. We have never had a problem. How critical is it to have this line dug up (8' down) to replace this section of pipe. Would you call this elective surgery? The pipe is plastic according to the inspector with the scope.
Check Hydro Physics. You will then really be confused. I just went through this, paying over $5,000 for replacement of a slightly bellied 4" pvc drain pipe running from the house to the septic tank, only now to seriously question whether I wasted over %5,000. In my case, our house was being sold, and the buyer insisted on having the system inpected and having a belly in a pipe corrected. Unfortunately I used the same plumber who said I had a belly problem to charge me over $5,000 to fix the belly problem. For me it was the same old, same old. If you ask a surgeon if you need surgery, you are going to get some surgery. I am guessing few drain pipes leading to septic tanks or public sewer lines are perfectly level, and practically all have some ups and downs or sags alias bellies. Be skeptical, get second opinions, require the plumber to qualtify in increments of .25 inches the sag, and negotiate the price.
