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.
