I can't help you with that one. The reason it was recommended to run a second pump for your UV is so you can tailor the flow to the needs of the UV, without disrupting flow back to the tank.
Ive never run a manifold, and I don't feel comfortable giving you advice on something I have no experience with. I'm sure the guys above can help there
