Common questions

Is it safe for gasoline and diesel?+

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

How do I start the siphon?+

Submerge the brass 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 brass 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.
