Ballast Question.. yes, another

[stretch55]

I was wondering if this would be possible. I would like to have a dedicated pump per bag in my system. I see alot of people adding the Tsunami 1200's with vented loops. Could I add 3 1" scuppers, 3 Tsunami 1200's and still use my 1" Irritroll 700's instead of the vented loops? Or would it be a faster system to go with 3 3/4" scuppers, 3 Rule 2000 pumps and the 3 1" Irritroll 700's?

the rule pumps will faster, but for the price-get the tsunami's. go with the 1" thruhull, not scuppers, since you allready have the valves just use those.

So you are saying I can use the tsunami 1200's with the 1" Irritroll 700's? Also if I have the Irritroll valve to stop the water flow why not go with the 1" scuppers over the 1" through hulls?

dont see any reason why you cant use the valves with pumps-just wire them together so when the pump turns on the valve opens. Reason for thru hulls instead of scuppers-with the scuppers you also have to drill 4 smaller holes into the bottom, and if the valve idea doest work and you have to use the vented loops -the vented loops and scuppers dont work together.

if you go with the 1200 tsunamis make sure to get 2 hose adapters per pump as the thread size is not compatible with dang near anything.

Technically I don't think they are called scuppers, but that's a different discussion. The scoop strainers like the stock one require 4 screws and lock you into either using valves or modifying the strainer itself. Using mushroom thru hulls is a cleaner install with fewer holes, more flexibility for future needs, and less under hull turbulence that can interfere with speed/depth sensors.

It's all personal preference on vented loops or sprinkler valves or check valves. I went with check valves on the rear bags and vented loops for the front.

Well if I go with 3 3/4" "scuppers" with 3 brass shut off valves, no straine/filter, 3 rule 2000's, 3 irritroll 700's. obviously this is 1 scupper, 1 pump and 1 valve per bag. Then basically all I am doing is eliminating the single intake and the manifold and just dedicating 1 intake, 1 pump and 1 valve per bag. Since the irritrolls are the straight thruogh design and not the up and over like the stock valve then the system should be pretty fast right. I also think that since I would be going with the rule 2000's wouldn't I need to keep the scoop style scuppers for the intake? I think that moombadaze did a 750 bag with just the rule 2000 in like just under 5 min. I don't think that the irrotrolls would slow any flow down since they are straight through flow. So since I have 2 250's and a 600 the whole system with dedicated pumps and intakes should take less then 5 min to fill. Correct???

Those valves aren't a full-flow design. They are less restrictive than others, but still restrictive. They also take up space and are another point of failure. Once you go to dedicated pumps I'm not sure why you wouldn't just throw a check valve or vented loop on there and be done. Simple and efficient.
