Pond Boss Forums POND CONSTRUCTION Building a dam Replace galvanized outflow pipes with plastic?

They now make a stronger version of the ADS black plastic pipe it's more rigid and will handle more head pressue than the standard stuff according to the manufacture. I recently replaced my black pipe which had a blow out under the dam http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Main=22034&Number=279372#Post279372 with the new rigid type which is grey in color. You can also install aluminum piping as another option. The plastic stuff is not intended for high head applications but I beleive a paddle wheel scrapper or D6 dozer from recent pond work did mine in not head pressure. Here is a link to the ADS site http://www.ads-pipe.com/en/ you can probably find a sales rep in your area to purchase it.
