Gravel vac problems

[dramaqueen]

For some reason, I'm having problems getting my gravel vac to work. I filled the cylinder with water and moved the thing up and down but it just doesn't work. Does anyone have any pointers for me?

Suck on the end of the exit tube until water starts flowing into it freely then drop the end in your bucket. Suck slow or you get a mouth full of tank water.
