Overflow Issue

[bjrouse]

Hi guys,

I changed my design and made a new overflow as per designs on here.
Here is a video of it.
It is completely, or at least to my knowledge, air tight.
It loses siphon when I turn the pump off and the whirlpool type suction of air is annoying.
Any ideas.
Could the whirlpool make it lose siphon?

nice work...........


it might loose suction because of the air going into the pipes. i was going to say to use a air line tubing and stick it down the drain to make that noise go away but that will also break the syphon.... maybe put a 180 at the top of the drain tube..may kill the noise and the stopping of the syphon..GL buddy....kewl design..

Hey bjrouse the problem i see is that your inlet U is higher than the outlet U ..They have to be a MIRROR image of each other to keep the siphon...

The long pipe, (Vent) is their a hole drilled in that cap?

I read somewhere that the outside should be a little lower that the inside?
I wil shorten it up to make them a mirror.
What will happen when the falls below the inlet. It seems to suck air and lose siphon? Does yours and will making them a mirror solve this?

Cheers

No. The cap is just pushed on. Not glued and no hole

You have to keep the U pieces Mirrored. Your inlet is higher than the output U so the water goes lower and sucks air in the inlet tube when power is shut off.... Keeping them EVEN you have equal pressure on both U pieces and they hold water....

There might be your problem either drill a small hole in it or take it off.
