Is it a drain system with perforated pipe, if it wasnt installed right
it might be clogged with sand and worthless now. There is a right way
to do it to code. I have one thats near 100 years old and flows like
the day it was installed. For sand a plastic sock probably should have
been used to keep out sand. You need to dig up a section to see its
condition, how it was installed and protected from sand, and consult a
few real engineering pros and talk to a lawyer. You need to get on
record before that warranty expires.
