Could a 2-yr-old French Drain Failed?
Could a 2-yr-old French Drain Failed?
(OP)
Have a water basement problem again in the same area where a french drain was installed two years ago. Why did the system fail after two years? Contractor installed perforated pipes, backfill with clean crushed rocks, and wafers to divert the water to the existing sump pump. What would be a new solution to completely divert all the water and prevent it from seeping between the cove? thanks

Did you ever verify if water was discharging out of the pipe (right) after construction was completed? If there was water at the outlet after construction, and no longer exists there, then you can assume that the drain has failed.

Well, the Titanic "failed" on it's maiden voyage...
Point being that unless the installation is performed correctly, implying that shortcuts were not used to save $$$, the drain could fail very easily. Clogging of the system cue to siltation is the most likely scenario here. There are others.

We have a local plumbing company than can inspect drains down to a 2" dia. Instead of the standard "tracked or wheeled camera" that is used for sewer inspection, there's a smaller "snake camera" that can be used. This camera system looks like a small garden hose, wound on a spool that you can feed into the drain. At the end of the unit is a small camera and lighting system, about the size of a quarter. This "snake camera" is very flexible and can be fed into drains with mutiple bends. Our contact also provides a digital copy of the inspection.
Traditionally we've used this operation for inspecting private sewer connections but have also used it for french drains.
