I hope you dont mind me contacting you, but after browsing the web for an answer to my problem I came accross your posts and found them very helpful, and wondered if you could shhed some light on my problem.

Recently purchased an old house that has a septic tank for sewerage. After lots of bad smells, leaks into basement I have dug up and exposed the pipe leading to the tank.

I have discovered a hole in the underside of the cast iron pipe about a 4 inches before it eneters the tank.

I am guessing the best bet is to replace the cast iron pipe with PVC pipe (Sched 40?).

I was only going to replace a section of the pipe about 3/4 feet as the rest of the cast iron pipe seems pretty solid and I dont really want to have to work on feeding a whole new pipe from the basement.

My main areas of concern are:

How to connect the new PVC pipe to old cast iron. Some info I have found suggests using donuts, others epoxys. Do I use purple primer?

Another huge area of concern is where to remover the cast iron pipe at the tank. Does that pipe inter the tank a bit, or is it flush with the exterior wall. at present the cast iron pipe is surrounded by concrete or a putty or something (my apologies, as youcan gather I am pretty clueless!!). Does that all need to be removed.

Also, what would be the best way for me to connect the new PVC pipe to the tank. Is there a putty, or do you use quikrete as I saw somewhere.

Thank you so much for taking the time to read this. Any advice would be grately received
Sincerely
