Baotchi, Prolly whats going on is you didn't get all the air out of the pvc
I primed mine by submersing it in the tank, and rotating it in all directions until i was sure 100% of the air was out of the system.
Right now, I am getting the 'super suck' effect. The siphon works GREAT, but once the water level in the main tank drops low enough, it sucks air into the system, much like a toilet flushing.
Not sure how to correct this, so I am still playing with it. Without the collection cup, it pulled the top 3" of water off my tank in less than 10 seconds. Not sure what GPH
that works out to, but its impressive, to say the least. I have a submersible pump in the sump tank returning water, that flows at about 300+ gph
, not sure of the exact rate.
Anyone have suggestions for the "toilet flush" effect? Once it sucks air in, that's it.. Siphon is over.
