Review on 🔌 NDS 1244 Catch Basin Outlet Adapter - Fits 3-inch & 4-inch Drain Pipes, Color: Black by Jay Ngo

Poorly designed camlock system. The ease of installation is great and it connects nicely to my drain pipe, but if you don't mind, like I didn't, the large holes on the cam locks remain open. The holes are approximately 1/4 inch. During a light rain, water never entered my drain pipe and I ended up with water underground. I dug up the pool again and siliconized the mating surface but didn't see any holes. This time I tested the water before digging in and finally saw the water splashing at the bottom. I will siliconize the cam locks and hope this is sufficient.
