how to get my overflow piping working?

[markietan]

mm... i diyed this 2 yrs ago but today i fixed it up and can't get it working.. normal siphoning works but i think the idea of this piping is so that if there is not enough water in the main tank, it'll stop siphoning and it will resume siphoning when water is topped up into the main tank... right?

once the thing stops, it won't restart again even though the overflow pipe has water in it...

help.....

ok i think i found out what's wrong. there was a tape covering the hole i drilled on the end cap, which is why atm was not established... it works now. hah

haha..you can try inserting an airtubing to the hole. it will be less noisy too plus doesn't cause salt to be deposit at the hole.

Cheers.

how long is the inner tube?? the design looks wrong....

the outer U portion has to be lower than the inner one.

yup the inner tube is shorter than the outer u portion. it is covered by the white pipe with holes drilled ontop, which i'm using as a overflow compartment for now. =)
