Any pics of the broken piece? I know what a venturi looks like.....What about just replacing the venturi, not a piece of equipment that I'd 1/2 it on....skimmer is important.....
just found a supplier for the venturi it cost 27 shipped if anyone else has the problem can email me at dstorey7@comcast.net seems to be the cheapest by far that i found
one last thought would JB weld have worked as long as it doesnt enter the water area at all. I was thinking of applying that around the edge of the venturi nozzle while i held it tightly in place.
I would honestly just replace it....AquaticEco, ThatPetPlace are a few places I know of for sure that have them.....I do know AquaticEco has a couple choices on venturis'.
