Mine did not work when I first tried to test it

Pump did not work when I first tried it...had to unscrew the bottom where the pump was located. Whoever put this together at the factory did a really poor job. They had the wires to the pump connectors twisted around the tube and had it crimped so badly that the liquid would not be able to get into the pump itself. I fixed it and also installed an extra 10 ft of tubing for those of you who, may be like me and too old to carry around a 4 gallon tank on your back...I strap it to a dolly and now I have something that is VERY useful to me.
