Does any one know the maximum flow rate through a 1" bulkhead?
 
If I remember correctly it's about 600 if straight down, but I think atnixon (I could be wrong but I think it was him) said he could only get about 350 or so. Have you used a head calculator to figure your plumbing?
 
Hey jojo I found a total dynamic head calculator, is that what you mean? Well my TDH was 1.44 and I have no clue what that means.
 
Nope.Well this is what I got on it Total losses are 4.93 feet of head pressure, or 2.13 PSI. with a flow rate of 537 GPH. I'm pretty sure a 1inch bulkhead can handle 537 GPH?
 
The number that is coming to my head (it's been a while since I plumbed anything) is 600, you could always run a "t" off of the return to slow it down if needed.
 
Does a "t" split the water flow? Or does it block it a bit? If it blocks it and doesnt let the pump pump water, wouldn't it mess up the pump or can most pumps handle the pressure?
 
It splits it you then take the extra water and run it back into your intake section.
 
Wouldn't making a bit of the return back into the sump make it flood? Lets say the pump is 600 GPH so you split it in half to intake and tank. The 300 GPH going in the tank makes the overflow 300 GPH. Then the pump being split in half adds another 300 GPH going to the sump. So wouldn't it be like 600 GPH going to the sump and 300 GPH going to the main tank? Also does a "t" split the flow in half or can you adjust it? I'm confused
