eshopps overflow? Update

So it worked fine with no air in the U tube until today and it was just creeping water through again like in the horribly out of focus picture above.

A lot of bubbles are coming from the intake end and I do suck the air out with a 1/4 airline, which i love so much to do.

Are you saying to raise the box or lower it?

The next time it loses water I will check it again thoroughly for hairline cracks. If there is a crack is there a repair that can be done or just replace it?

I have wondered if flow might be the problem the bubbles going through it move pretty quick but i don't remember how fast they moved before I got the new pump and it is always the same tube getting the bubble. I worry about changing my pump speed due to possible overflow.

 

I kinda forgot, but I think lowering it will keep less bubbles from entering the intake?

 

I would honestly not make all these adjustments until you replace the u tube. It's a common problem and a cheap one at that. I went through the same thing and I wish I didn't beat my head against the wall and just bought a new tube.

 

Update: So the U tube which was losing pressure has been doing fine recently. I think i restarted the siphon on it twice since i first posted. But the other one has been doing it now.

So now I know there is some other factor rather than a hairline crack letting air in. I increased my pump speed so I will test that and see how it goes, which is hopefully not all over the floor.

 

And btw, this problem is fixed.
