i wouldn't say lost but yes for it to be effective i have to move the valves. i do it usually in the evenings. it will be easier when i get my pentair automation installed
So I finally talked to my buddy that I gave the all in one to and he says it works as advertised he has an old pump with no vsp so he doesn't have to turn any valves off. He said it really does create the venturi effect and works great. So what I'm getting out of the all in one is it doesn't work great for variable speed pumps on low rpms which defeats the purpose of vsp. Hope this helps.Any updates on how this is working for the folks that have tried it?
I went just bought one and have the exact same thoughts you have about it. I have a VSP pump and do not want run at higher speed if not necessary. I also cut back on my main drain and did not notice any improvement. What now?
I am trying to understand the mechanics of how this thing is supposed to increase the velocity through the skimmer opening. The flow through the opening can be expressed by Q=VA.
- Q (flow) is determined by the pump. This number doesn't change whether the skim-a-round is installed or not.
- A is the cross sectional area of the skimmer opening (WXD). The width is fixed.
So, the only way this device could increase the velocity of the water is to reduce the water depth going through the skimmer opening. I don't see how this is possible...
