Pump Dying?

I found that the lower the siphon is in the box the faster it purges air. The added pressure of the water above the pipe helps push the bubbles out. I also found the greater the distance between the emergency and siphon the more room there is to dial it in, when both pipes are too close to each other the water level has a hard time equalizing. The level can surge back and forth and never stay stable long enough to purge air in the sihpon. The only solution I found was to lower the siphon. This does suck for water draining back when the pumps are off.

I doubt your pumps are failing, it just sounds like your having minor issues with the water stabilizing in the overflow.

Its a pain but don't give up!

Yeah! Mine is not 6 inches or lower than tbe emergency drain. More like 3-4 inches below right now. It was higher, like 2 inches lower than tbe emergency, but I had some issues, cut it lower and it helped. I saw this article, but I couldn't bring myself to cut the Herbie 6 inches lower cause of all the water that would fall in the sump during a power outage.

I'm waiting on carbon block filter for my ATO. When that comes in, and I run my drip line, I'm gonna reconsider cutting the Herbie shorter.

Once the tank level is below the weir you're only losing water in the overflow, not the entire tank unless the overflow is not sealed below the weir.
