FAQ's

I have received my jerry can and it has a residue inside which smells of fuel?

Our cans are rinsed out with a cleaning fluid after they are manufactured which does have a fuel-like scent to it. We can confirm that this is normal and does no harm to the can or the fuel that is then put inside.

Are the Wavian/Site steel fuel cans suitable for water?

No. The coloured steel cans are lined with a rezinol lining inside and are suitable for fuel only, not water.

What is the difference between a Wavian Steel can & a Site Can?

Our Wavian branded cans are top quality fuel cans. They are made to the highest standards to last a lifetime. The Site Cans are a more affordable solution to storing fuel & we wanted to give our customers the option of having a lower-price choice of steel can. The Wavian quality may not be matched, but they are a decent can for fuel storage.

We are expanding into a more modern warehousing facility. Please bear with us as we organise this transition. Orders will be delayed, but rest assured, we are working as hard as possible to deliver your items.

How to Clean up & Store
After us the filter straw should be backlashed with clean water
Draw clean water through the device, and then blow the clean water back through the mouthpiece. This will help clear the membrane surface of sediment and particles. Repeat 3-5 times.
Clean water can also be backflushed through the mouthpiece by using a pressurised water source (eg a hose or tap). For best results backlash in pulses. After shake out residual water from the filter straw and allow to air dry (do not place in oven or microwave), and then store the filter in a cool dry place.
