Plumbing check

[TonyCash]

My first time plumbing, (dry fit)before I miss anything, does it look ok? Left is primary drain, middle is return with check valve, right is emergency drain( will have another short pipe coming out of the elbow.

Also thinking of putting an T on the left drain to utilize both drain holes on my sump. Should I?

My only concern would be the 90 degree run of the main drain. If the flow on start up is not strong enough it will trap air in that pipe

Too many 90 elbows for my liking. It'll work, but not the most efficient. I try to use 45's instead of 90's. For instance, a 45 coming off the main drain and then another 45 into the sump.
If you haven't already, might want to consider drilling a small hole on the return line just below the water line in your tank. This will stop the siphon if your check-valve fails when the return pump stops. I never use check-valves.

This is on a SC Aquarium 150gal btw. Thanks! Ok, so I’ll order some 45s. I was going to order some Ts and ball valves to do a manifold any way.

manifolds should go off the return right? I was going to replace the one elbow on the return with a T, and run the manifold to the left.

I'll self-promote here for a sec (but it's on topic!):

The pipe on the far left is crooked and that extra pressure may cause it to fail!
