Common Questions

Is it safe for gasoline and diesel?

Yes. The hose is anti-static and petroleum-safe, and the jiggler nozzle is lead-free copper — built specifically for gas, diesel, light oils, water, and non-corrosive chemicals.

How do I start the siphon?

Submerge the copper nozzle end in the liquid, hold the outlet end lower than the source, and shake the nozzle up and down a few times. The glass-ball check valve primes the hose and flow starts automatically.

How do I stop the flow?

Just lift the copper nozzle out of the liquid (or raise the outlet above the source level) and the flow stops.

What's the warranty?

Every FlowPro siphon carries a limited lifetime warranty. If it fails under normal use, we'll replace it.
