I heard a lot of people use their mouths to start their gravel vacs... that's just...
So how do you start up your gravel vac? There are actually many ways to do it I think 0.0 here's how I do it.
I fill the big cylinder thing you attach to the hose with water and take it out of the water. I face the opening up pointing towards the sky, and in my other hand I hold the other end of the hose also pointing to the sky. So it makes a U
shape. Then the water will instantly flow, and when it almost reaches the end of the hose I put my finger over the end. Then the big cylinder thing drains all its water into the hose.
Next, still holding my finger over the end of the hose, I stick the cylinder back into the water (I make the air bubbles go away first) Then I put the hose end into the bucket. I let go and it starts sucking... this process usually takes me 10-30 seconds.
Just thought I'd share so that I'd save people from swallowing fish poop water. I lost the instructions and had to figure this out myself... took a long time.
So how do you do it?
