Customer:
I received a mini water pump and connected it to a 4V battery, but it doesn’t work. According to your tutorial it should operate at 3 to 6V. Could something have been damaged in shipping, or am I doing something wrong?

Poštovani, nedavno sam naručio neke stvari sa vaše stranice uključujući mini pumpu za vodu. Danas sam primio pošiljku, kako god mini pumpa ne radi. Spojio sam zice na bateriju od 4V te ona ne radi. Prema vašem tutorijalu sa stranice treba bi raditi na 3 do 6V. Jel moguće da se nešto poremetilo unutar pumpe zbog dostave ili možda ja nešto krivo radim?

Soldered Support:
Are you testing the pump in water or out of water? Did it work out of water?
Original message (Croatian)
testiraš li pumpu dok je u vodi ili izvan vode? Je li ti radila izvan vode?
Customer:
I tested it out of water. I don’t see the impeller inside spinning.

Poštovani, isprobao sam ju van vode. Ne vidim da se turbina unutar nje vrti.
Soldered Support:
You need to use the pump underwater. Which exact pump do you have? Can you try at a higher voltage? Make sure to test everything while the pump is submerged.
Original message (Croatian)
pumpu biste morali koristiti pod vodom.
Koju točno pumpu imate? Možete li probati na većem naponu? Svakako sve probajte dok je pumpa uronjena.
Customer:
I tried it underwater as well. The pump still doesn’t work. I connected it to 5 volts through an Arduino and it still doesn’t work.

Pozdrav, probao sam i pod vodom. Pumpa ne radi. Spojio sam na 5 volti preko arduina i isto ne radi. Lijep pozdrav, [name removed].
Soldered Support:
My colleagues tell me that pumps can get stuck from sitting. Try manually starting the pump while it’s powered by pushing an object against the impeller to rotate it manually. After that it should work fine.

Kažu mi kolege da pumpe od stajanja “zapeknu”. Možete li probati ručno pokrenuti pumpu, dok je pod naponom na način da gurnete prema turbini objekt kojime ćete ručno malo pokrenuti pumpu? Nakon toga bi sve trebalo biti u redu.
Hvala!
Customer:
I did what you suggested. The pump now works. Thank you for the help.

Poštovani, napravio sam kao što ste mi rekli. Pumpa sada radi. Hvala na pomoći, lijep pozdrav, [name removed].
