HOB Overflow Box, Water Lifter Direction...

[JTP424]

Ok... So first off, apologies for the horrendous paint drawing...
I have an Eshopps HOB Overflow box that I am working on installing that I picked up from the original owner of the tank.
It uses a bent tube for the vacuum. He superglued a hose in the highest point of the tube and used a water lifter to ensure vacuum held when power was lost and came back on etc.
I did NOT note which direction he had the thing plumbed....
Do I want the water lifter to SUCK the potential air out of the top of the tube? Or do I want it to drip water into the top of the tube.....
Red line below is where the hose is basically glued....

Suck out.

However,if you have sufficiently high flow you will not need to remove bubbles as they will flow out in the turbulence. If you run low flow to sump, this is good solution.

Thank you!
He said he had continuous bubbles even with his pump turned up all the way... So I'm going to set it up with this as more of a safety measure.

How did the set up go? I am setting up mine in a week. Any tips or tricks that helped you? Besides the basics. Did you make sure the siphon tubing is below the acrylic, next to it? I saw it on a YT video and that made sense. HMU if you want the link.

I'll grab some photos when I have a chance. It works great! The glued hose is a bit weird and collects algae/debris, but it works wells as a backup restart.

The hose isn't needed for eshopps hob overflows. The only time a hose is needed is when first getting it started to remove air and get the syphon started. I just fish a piece of tubing into the U tube and suck the air out. I ran two tanks on pf800 over flows. The tank below had two with a basement sump. Never lost syphon when the return was shut off and never had a flood in over 6 years running. The only way i could induced a flood was to crank the return up so it pumped more water than the overflows could drain. Other than being a bit noisy mine performed flawlessly.

Thanks! You're correct, I only have it in case the power does go out... I have various contingencies for avoiding overflows ha!
