Drain tile leaking at Y joint

We have some seepage problems in our basement, so are installing exterior drains and piping the water away from our house. Corrugated plastic drain tile pipe (no holes) runs from one drain into a box drain. Pipe runs out of the box drain into a Y joint. Pipe from another drain runs into the same Y joint. Then the water runs out of the Y joint, thru another pipe (same drain tile), down out of the lawn. As water comes out of the Y joint to run down the final pipe thru the lawn, the water leaks heavily at the Y joint. We have the connections as good as we can, and even put a clamp around it, but water still leaks. Since it's corrugated plastic, I just think that the seal in the Y joint isn't a good one. Any recommendations on how to make this a water-tight seal at the Y joint?

As long as you use the corrugated stuff, you will have silt accumulation in low areas, "bellies" in the piping and a pipe that cannot be connected tightly. When the rains stop, the ground water can seep an and deposit more silt.

I hope you are not combining buried drain tile with downspout discharges that produce different amounts of water at different times.
