Hi All, Newbie here...
I've put in my pool about 15 years ago, and got the A&A pop ups in the floor. The actuator is the low profile model, with 6 balls in it. Thankfully, it comes with a lifetime warranty, as I've had the pop ups replaced twice, and the gears in the actuator replaced twice, and the actuator housing replaced once. In fact, I just finished replacing the second set of everything, less the actuator housing.
It's working well, with one exception. One zone runs (leaves the pop ups, up) for about twice as long as any other zone. I've adjusted the speed by rotating the lid, and while it changes the speed that the pop ups cycle, that one zone is always about double of the other zones. This particular zone has two high flow heads, and three low flow. The one that proceeds it, has two high and two low. It cycles at the same speed as others, so it's not back pressure slowing the water flow. It appears the impeller inside of the actuator is turning at about the same RPM, regardless of the zone.
I'm stumped. Any ideas???
