Ptown.... was just putting more info into the differences not answering your question. realized I forgot to put the link in the post as well (pwi).
3 less pumps, no one way valves, 3 less sets of drain lines, no vented loops, less space required for pumps, and you will not get the same fill/drain times unless you go to 1" lines. Also in the timings a 3800 rule pump was being used to get down below the times I get. I can fill/drain at a rate of approx 100 lbs a minute per pump verified on video. Not sure what a 800 tsunami can do but I bet thru a 3/4" line its more like 30 percent slower. But I am hoping someone can prove me wrong. I found a mod that used the 1200 tsunami's on 1 inch intakes and 1 inch lines that is taking around 5 mins to fill a 750....thats fast and quicker than my jabscos.
So although the pumps are more money, you need less of them and less parts, so not sure how much cheaper the system really is.
