4" drain cracked at elbow

[Mar3232]

I know it probably doesn't exist but I've had a piece of 4" pipe that is the inspection pipe for my drain field that has been cracked straight through and I've repaired it before only to have it fail several months later.

The trouble is that to replace the section of pipe will be a nightmare because of the soil etc.

Is there (probably not) SOME sort of flexible? pipe that is used to fit snugly on the INSIDE of a 4" drain pipe?
Something that is meant for a temporary or even permanent? repair? -- thank you

Say more. How long is the pipe? Is it PVC? Is it sticking up in the yard, and got hit by a riding lawnmower a few times?

Is this drain field for your septic system?

There is 4 inch OD galvanized fence post. That would rust after a while.

There is 4 inch OD stainless. http://www.speedymetals.com/pc-4515-8276-4-od-x-065-wall-tube-304-stainless-steel-annealed.aspx is the first place I found.

It's a 4" PVC drain pipe leading to drain field, yes it was above ground to some extent so probably cracked by getting hit. I tought of cleaning it again really well and then adding some steel reinforcement on the outside of the pipe (like those little braces) but would love to see if they make something that fits inside the pipe. The section is just 20" or so, the length of an elbow and a bit of the ends.

https://www.pvcfittingsonline.com/4-schedule-40-pvc-pipe-inside-connector-s0302-40.html could glue inside for the top part.

An inside PVC toilet flange could glue inside. You would need to cut much of it away.

A 4 inch coupling would glue outside. You could maybe hold the inside against the coupling for the short time that it would take for the cement to set. You could then extend the pipe higher if you liked.

Oh man -- thanks ! ! An inside connector will do it. Gives me plenty to work with. Didn't know they made that.
