Are my downspout outlets plumbed correctly ?

[DMY]

I have three downspouts which drain into the same outlet. It doesn't look right to me. Could someone comment before I call my local plumber to get a quote ? picture attached. thanks, D

That looks like a picture of a plumbing fail you'd see on Facebook. Like a joke.

Perfect example of what would be on an error sheet on "how not to install a leader line."

few things look wrong mainly that tee are you wanting to divert the water under the house and pumping from there? the connection of downspout to the 45 kinda hokey but least of your worrys is your pipe sloped in direction you want?
this should be stuff that if you get interested can be done by an owner

They make very nice adapters from rectangular downspout to 4" drain. Lots of nifty stuff at big box stores.

What does this drain too? You're right, nothing is right. All that silicone might as well be duct tape. Obviously water backs up during a rain event.

I think DMY is now AWOL as is whoever built that
