I initially did it this way but then after seeing the comments about how this is not the best way to do it i took it apart and used pvc coupler pieces with pvc primer/cement, it definitely feels more solid and durable that way. Although this method may hold for decades, if you've already going to be there digging up your yard just do it properly.

Best channel name EVER. Also, great video- Thanks!!

Thx for video although I may go with an all pvc coupler with glue good to still see how it works

DO NOT use those quick connectors underground. Ground movement will cause them to come loose and you sewage pipe will fill with dirt. This isn't just wrong, it's extremely lazy. It's not difficult to use a proper connector and glue in this case.

Any limit to how high you can extend? I have a perf pipe below surface behind a 5 foot retaining wall with crushed rock fill, and am adding a vertical 4" pipe (with grate) at each end to drain the surface water. Thinking about connecting the vertical to the perf with a 1 way cleanout. Will that cause any problems?

How to not do it

Is there a code as to how high above grade a cleanout should be/ how far out it should stick out?

prob glue it is better

Why would you not do a proper glued joint? this just seems lazy
