PLUMBING QUESTION

[sp1187]

I'm looking at starting a frag tank and running it in line with DT.
This is a pic of the return to the DT.
If I run a line off the currently capped end to the frag tank and, use a gate valve to restrict the flow to the frag tank,
will it cause me any issues?
The pump is a Syncra SDC9.0 with plenty left to go flow wise.

Make sure you break the siphons so one tank cant drain into the other if the power goes out. Other than that all you are doing is making a manifold really.
I am not sure what problems you are expecting other than increased drain back and the normal stuff.
1 run 3 tanks off a sump but with separate return pumps and drains. It's the same as one when you run it.
