I think that the numbers Via advertises aren't worth wiping a dogs bum with. They say 400 GPH and 6' of head, but I found, in a low resistance system, that I was looking at about a quart per minute at 2ft lift. I can't see that thing getting 400 GPH if you were pouring water through it over a cliff, and even in solid hose I couldn't get more than 3.5ft of lift out of it. Maybe mine was defective, but it was just absolutely terrible. At first I thought my system was plugged until I put the other pump on it and I had flow like crazy going through it. Then I tried the lift test and chucked it into my closet junk bin.
