See the black overflow section, if water level falls below there, it cant pull anymore water and sits idle, while the other side has its own little box there, so it cant have air fill there as the drain side over draws leaving a air space.. I havent heard of anyone having a issue with this setup asides from the same flood anyone can get, of not cleaning out your hard lines once in awhile that drain into your sump.

did you buy you eshopps HOB skimmer locally or from eBay?

Locally, I bought it at oceans city off 16th

And ill add, there are a few videos on youtube you can check out that show people unplugging the system.. showing you it doesnt lose the siphon, and re-plugging it back in to start working as it should.

They can still loose siphon, air bubbles can still build up in the tubes eventually breaking it. You also have to maintain a certain flow rate per siphon tube for them to work reliably.
