diy overflow

it sounds like it would be continually sucking any air that may start to gather in that loop, i think hes got it , congrats
 
Dr Joe, this was my thinking exactly. The problem is that air gets trap at the top. So I'd be using the downward flow to suck out the bubbles. I the only problem that i see with it is that the bubbles might not get carried with the flow down the pipe. Something to fix this would be to attach the bottom of the airline to the "U" part under the "T". It would still be in the water during a power-out, so you wouldn't lose siphon. And the carried out air would rise up and out the airpipe.
 
Dr. Joe, that is exactly the purpose I was thinking of. Using the airline to suck out the built up air that gets trapped. The only problem I see is that the air bubbles might not get picked up by the flow and just rise up again. I think this can be solve by putting the bottom end of the airline on the "U" underneath the "T". The airline would still be under the water during a power outage, so siphon would not be lost. And the air bubbles coming down the airline will rise up and escape through the air pipe. Let me know what you guys think.

i think you are spot on with that idea,i would put it just after the "u" and under the "t":) great work spoot
 
I wonder if I'll get it named after me...lol. First things first though, we have to make sure it works..... A overflow made of clear PVC would do the trick, then one could whether or not there is any residual air left in the top. Using an airstone to introduce bubbles into the siphon, will help build up air faster in the top.
 
wow that is so weird as i was typing in my reply i was thinking about suggesting making a transparent set up to see it work,but i was in a rush,,
how about,,,,,,,, the anti air spoot:ROFL:

Riddle me this CHOMPMAN... after the air is out of the unit could the tubing maintain it? (cut the bottom of the tube at an angle for better suction).

Hhmmm. (We may just have to give spoot a gold star...)

Spoot definitely gets a gold star

The ability to create a venturi effect is going to depend on the flow rate through the overflow. Mine definitely won't support it. I am sure that drilling a hole in the tanks return for the air line will probably do it.

As an overflow ages, it builds up growth on the inside that off gases terribly. If my system is shut off for a day (happens a lot), I have to remove the trapped air or they will not restart. I also have to purge the air periodically or they will stop working every three months or so :irked: I wonder if a Spoot Tube will work with a check valve in place. I'll play with it and find out.
 
Spoot tube, I like it :D

I think the airline needs to be submerged in the event of a power outage, otherwise the siphon will be lost and the overflow will drain. Unless that's not what you are referring to ;)
