How to troubleshoot not getting any water from your high pressure pump! Part 2

Here is PART 1 on troubleshooting a high pressure pump.  LINK

This problem I believe depended on the time a customer allowed the bay to unload the high pressure.  Which varies greatly and would make this problem almost seem random.  You would also need to pay close attention which I did not…. This would be no problem if you only have one pump or one bay.  🙂  (I checked this pump around 3-4 time…. Sad to say.  The problem is the pump actually works completely fine.  Like video below…. Pressure just seemed high.)


In retrospect after fixing the v-belt on the cat pump…. I remember previous issues I have had.  I had to reset my motor started for some reason?  Now I know why.

At the time I tested the bay and everything was fine…. I thought. I believe now I did not test the gun like the video. I do remember thinking it had high water pressure and I needed to turn it down though.

After I fixed the belt and I thought I was finished with my repair…. I tested the bay.  The bay then popped the breaker.

Which was a surprise…. Usually when repairing one problem it fixes the problem! 🙂 This meant there was obviously another issue.

So I reset the breaker and this time watched and payed attention to how the high purchase gun was working. (Like the video above.) After looking at the pressure problem again it seemed like it had to be the unloader.

I replaced the unloader and the unloader fixed the problem.
