We have a Koi pond and a pool. I have never figured out what these are for. Any help would be appreciated.
its impossible to tell from those pics..if you want to find out cut off the caps and stick a hose through there and see where the water goes
Since its a koi pond and pool, can you tell if there is a bubbler or fountain pipe in the middle? They could be for a pump attachment for the pond or a slide for the pool.
Those end caps look like threaded caps. It's possible they may simply screw off and are for a liquid feeding system(looped back to pond) or water feature beside the pond. Multiple possibilities. Post some pictures of the rest of the plumbing set up and the pond itself.
