ill make some assumptions so you can see how i do it... then you can fill in the right numbers and give it a shot yourself.....
(Ill guess the sump is 10" wide?) 8x5x10 + 9x10x10 + 7x15x10 /231 = 10.17gal
then you need to calculate how much water will flow out of the DT when the power goes out:
example for a 75: (cant remember which you decided to go with)
1. how much water does the overflow hold (i'll guess): (4"x4"x19"/231 = 1.32gal)
2. how much water will drain into the overflow (lets say the baffle is 1" below the surface) (1"x18"x48"/231= 3.75 gal)
3. also account for how much water is in the pipes... pi x Rsquared x lenth of pipe /231 (ill guess): (pi x .625squared x 120"/231 = .65gal)
4. also sinse your fuge is seperate and the water will try to find the lowest point (as you already know) how much will drain from the fuge...(20T? ill guess) if the pipe is at the water line then 1.25" will drain out.... so (1.25"x24"x10?"/231 = 1.30 gal)
so 1.32 + 3.75 + .65 + 1.3 = 7.02gal is how much you need to account for or roughly 7.5 gal...
of course when you do this you have to measure and re-calculate using the right numbers...
good luck & let me know how you do...
