return piping under-ground

Snowmelt

is there anything wrong with connecting the return like this ?
the pipe on the right is below the pipe on left, the pipe on right is a return that goes under ground ( there is a door that it goes under). the pipe on the left is connected to the hart ford loop. the pipe coming down on the left is the second return in the system which is a no brainier .

Exactly. The key thing is that the mud and rust needs to be flushed out periodically
