A few shakes to full flow
No pumps, no batteries, no mouth-priming. Click through the steps to see exactly how a FlowPro primes itself.
The secret is in the nozzle
Inside the brass nozzle sits an industrial-strength glass ball — a one-way check valve. Each time you push the nozzle down, liquid is forced past the ball into the hose; as you pull up, the ball drops back onto its seat and holds that liquid in place. A few strokes ratchet the liquid over the top of the hose. From there, gravity runs the show.
That's the whole trick: keep the source higher than the destination, and a 1" FlowPro moves up to 10 gallons a minute.
Troubleshooting
It won't prime
Make sure the outlet end of the hose is LOWER than the liquid level in the source — a siphon can't flow uphill. Then shake with short, brisk 6-inch strokes; slow shakes don't seat the check valve.
Flow starts, then stops
The nozzle probably came out of the liquid, or the source is nearly empty. Keep the brass nozzle fully submerged and tilt the container toward it as the level drops.
Flow seems slow
Increase the drop: raise the source or lower the outlet. The bigger the height difference between the two, the faster the flow.
There's a kink in the hose
FlowPro tubing resists kinking, but a hard bend will slow any hose. Straighten the run and let the natural coil relax in the sun for a few minutes.
