UV Steriliser help

[gd1985]

Hi all

I've just set up my UV steriliser. Now it was gurgling like crazy & spitting out air bubbles so I read the barbs need to point up.

Issue I've got is they only stay up if I tighten the valves. The bubbles/gurgling stops but it's literally tricking out into the return chamber if I tighten the output valve.

Also, the input on the left is kinked significantly so I'm guessing this also reduces the flow.

Any ideas? I can't mount vertically before that is suggested

Your pic didn't show up.

You don't need the barbs to be pointing up, you need the unit on a slight angle. Make sure the input side is a little lower than the output side. This will push the air toward the output side, allowing it to be pushed out.

ok first problem your hose on the left is kinked, that will cause huge issues, also the uv needs to be mounted vertocal with the inlet on the bottom

Ok great, thank you

So when I've tightened them valves to keep the barbs up I've messed with the flow rate haven't I?

I've had my sump rearranged by the guy from my LFS, he set the UV but I mounted it to the cabinet the following day

In his original post he mentioned the kinked hose. He also said that the UV cannot be mounted vertical.
UV doesn't need to be mounted vertical. Mine is horizontal, on a slight incline like I suggested to OP. No trapped air. No issues.
OP, one other thing you can do is max out the speed on your pump when you first turn it on. That will help push out any trapped air. Once the air is out, you can slow the pump down to the speed you want it at.
