2 to 1 Waste Water Pipe (washing machine and dishwasher outlets)

I recently obtained a dishwasher, but the problem was i had was only one outlet Pipe (not connected under sink) for waste water from washing machine and dishwasher and i could not fit them both in, so made a simple design to allow two waste water pipes to fit the one pipe.

Tested to fit a 4cm standard pipe, no leaks (after 5 attempts) but i have not tested running both outlets at the same time as this might be to much water to handle.

Feel free to use, and if anyone tests the two outlets
