We have this yard drainage tile system in our back yard. We have a half-dozen drain tile round grates over all of the pipes. One of them keeps turning up flipped over next to the pipe. It’s happened 3 days in a row.
The grate just slips into the pipe. Water pressure isn’t forcing it out. We think it’s maybe some kind of animal, Bigfoot, or an extraterrestrial messing with it.
According to the lawn and garden installer who supervised the job of laying the drain tile and pipe grates, the problem is either too much water through the pipe or critters. We’ve had no rain for the last 3 days yet we’ve found the grate upside down next to the pipe each of the 3 days.
I thought of getting a trail camera (critter cam) to catch whatever might be happening. But I’d have to order it because local hardware stores don’t carry them. We live in a residential area, but it’s a wooded lot. We commonly see squirrels, deer, wild turkeys, and even raccoons in our back yard.
If Bigfoot is messing with us, I could catch it on critter cam. That would be awesome.
So, it’s not impossible that an animal could be flipping the drain tile grate. But why? It’s always got water in it, and probably bugs. I think it would be easier for a critter to find water in the woods and bugs are flying around everywhere and on the trees.
I don’t think a human would flip the grate off. But if we had a critter cam, I could record it. They’re pretty expensive. I doubt Sena would let me order one. She’s going to try using sod pins to tether the grate.
Update: Sena put a couple sod pins in the grate to help secure it in the ground. She put some dirt around it so if a critter is messing with it, it’ll leave evidence. The rods are crossed with string around them to—confuse the critter?
