thanks for all the discussion in here, and actually the Utube is broken, so little bubbles got trapped in and that's why the overflow stopped, I need to replace another tube.
I will go get a long stand pipe.
thank you so much!!
I m happy with eshopps too partypa, just that I got a broken Utube, sigh~
to ezy,
so I should level the end of the hose higher?
to partypa,
what do u mean by prime it? so i can't just drill a hole on the Utube?
another question, once the power is off (return pump), it will suck water back to the sump, so should I drill a hole on the PVC(the last section which is in the water) ?
just found out another problem, where the water come out from the overflow hose, there r tons of marco bubbles, I already have a baffles, so no bubbles r going to my return pump and DT, but those bubbles popped and make my floor wet, is there anything I can do to prevent those bubbles?
