Getting rid of air bubbles

[tapeworm]

I have a leak somewhere in my return line. It is sucking in lots of air and I cant figure out where from.
Does anyone have a trick I can use to find the air leak before I re-build the whole return line?

this is probably going to make me look dumb, cuz I am not sure what you are talking about exactly, but can you put the line in water and blow through it? Then it will bubble where your leak is? :notsure:

It may not be fun, but just run a bead of silicone around all of your joints. You might get lucky and hit it on the first try.

If you had a leak on your return line it wouldn't suck air. There is pressure on a return line. It would be squirting water. I think!!!!

Not necessarily. It can act just like a venturi on a powerhead.
