Ok, after talking with jason at Wakemakers about all the diff. options for ballast upgrades. I think that I am going to do exactly what Fman did. The 3 tsunami 800'3 with vented loops and the check valve for the drain system. I have an 1100lb system so according to all the numbers it should fill in about 5 1/2 min. When I upgrade I am going to upgrade to a 1700lb system so that should fill in about 8 min. Better then the 16 1/2 min now with the sprinkler valves. And that is even after I upgraded to the 1" Irritrolls. So I will have those up for sale along with a Rule 2000 pump hopefully within the next 3 or 4weeks.
