Need an opinion regarding joint failure
Need an opinion regarding joint failure
(OP)
I recently installed 2inch pvc glued in lieu of 2inch 160 psi 160 psi slip joint gasketed pipe. The pipe length is 350 feet and is routed in a sweeping curve of about 45 degrees. The pipe was installed in virgin soil that is essentially a sandloam/gravel soil. I have been advised that this installation is subject to failure. Would appreciate any comments.





RE: Need an opinion regarding joint failure
The preferred joint for underground work is the gasketed bell and spigot joint. This joint is preferred because the joint has some flexibility should there be ground movement.
However, the concern for pipe failure is probably more significant for larger diameter pipe. The depth of the pipe will have some bearing on the issue as well. Climate issues such as freeze thaw will also have some impact.
If your adviser can point to a similar installation where the pipe is breaking, then consider replacement. Otherwise, consider the risk of a pipe failure. If the consequence of a pipe failure is not a big concern, then let it go. If the pipe does break, you can install a flexible joint at the location where the pipe break occurs.
