New Pond Overflow Repair Troubleshooting - 03/29/22 07:03 PM
Pond is within about 18" of being full pool and as it started climbing the overflow pipe (n12 18" culvert pipe) i noticed it was taking water thru the double wall.
I think they accidently hit it with the dozer or something, but either way, its not significant or a structural problem, but I'd like it to be tight. My ideas were as follows:
1. Drain the pond down about 6" via the bottom discharge pipe, get the level down below the gouge. Get a clam shell coupler and fill everything with blacktop crack filler on the outside. Reattach the coupler over the cut and zip tie/ratchet strap over the outside coupler
2. Repair from the inside: N1 caulking, flex seal tape, hydraulic cement? Hydraulic cement would be my choice, but I don't know how it'd adhere to the smooth inner wall of the pipe. Additionally, water is actively/slowly dribbling down the pipe, so I don't know how well either of these options would work.
Doing it right probably means dropping the pond level and re-sealing from the outside. The entire thing will be under water once we're full, so I don't really care what it looks like.
I think I'm on my own fixing it as the pond builder has since retired and has enough health issues that I feel bad getting him back out, even though it may be his fault. I'm confident I can fix it better than he can at this point.
