What's wrong with my Softwash system?

I built a 12 volt softwash system, and it has been working great… until recently. I used to be able to spray water or chemicals 35 feet. Now, it sprays about 10-15 feet. The pump is good and the battery is new.

Any ideas on what could be going wrong? Thanks for any ideas.

Sucking air somewhere on the inlet side would be my guess

Air leak

So are you saying that the hose that draws the chemical has a crack or hole in it somewhere that is sucking up air? If that is the case, all I would have to do is replace that hose, right?

The hose, fitting, valve or something. Not necessarily the hose.
