I have had an ongoing problem with my septic system. The person who pumps my tank thinks I need a new system. It is about 50 years old, but a new system is financially not an option. Last year while exposing the lines for a plumber to snake the line I found the distribution box curshed. A plumber checke the lines and found no obstructions for 30 feet (the length of his snake). I had a company replace the distribution box but my problem did not improve.
Yesterday I was digging to expsose the D box for another plumber, and noticed the pipe from the tank had no slant to it. Upon futher investigation I realized the pipe was seperated from the tank and had fallen below the output of the tank. When I uncovered and removed the lid, I saw that the exit port seemed to be ok, but there is decay of the cinder block/concrete around the pipe. The hole around the pipe is about 2" larger than the pipe. I know replacement is probably recommended, but it is not an option right now.
Can I plug the hole with hydrolic concrete or something else the leak around the pipe, or is someting else suggested? The area is hard to get to, so is there a patch material which can be used in a caulk gun.
Thank you for any advice.
