When my lake was built the builder supported the 8inch PVC drian pipe with 2 pipes drove into the ground next to the drain pipe he then secured the drain pipe to these supports. I have noticed that the clamps no longer are there thus the drain pipe has no support. It is about 10 foot high from where the 90 turns up and is now completly cover by water. Is there any reason to ressucure the stand pipe to these supports?

Thanks, Jake
