Hi Zep. Thanks for the picture. Can you explain what I am looking at for the entrance there? It looks like you took a piece of the pipe, cut the top off, and then joined it to the outflow pipe with a gasket of some sort? If so, can you use that to fine tune the level?
My pipes lasted about 12 years. I could probably get another few years out of them. My pond rises and falls about 6-12" in spring/summer. I wanted to put 4 in to give more outflow area to stop the rise. I was also thinking about using concrete box culvert.
