pump placement

[basserdan]

I would put another small res after the 4870x2 before the pump, just in case the flow is poor enough where you would want a little extra fluid to not "starve" the pump. I know you're cramped, but there's always room for some small res...a bay res may work well. I'm just worried that your pumps will have to suck the water rather than push it...

I like this idea but, it will likely require a couple of 90's right before the pump to make it. I'll search for a possible small res and see what I can come up with. Any res suggestions?

thanks so far
