I was on a job this evening and pressure started dropping at the gun. I looked at the water tank and the water level was at the top of the ball valve at the bottom of the tank. I assume it was sucking a little air so I stopped and started filling the tank. I added another 100 gallon or so and tried to finish up since I was just about done. Now I have hardly any pressure what so ever. Air in the pump? I did notice it cavitating a little bit when I had the gun open. This was after I added the 100 gallon. Water was still running through my bypass hose back to the tank. If I let off the gun for a couple of seconds then pull the handle again there is a burst of pressure but then it goes back to very little pressure. This pump only has about 30 hours on it. First time this has happened.
