Got alot of Water but pump will not build pressure

[Jones10101]

Put in a new point and replaced the old pump. Got everything hooked up and the pump pumps alot of water but will not build pressure and shut off. I even returned the pump and got another one thinking I had a defective pump. I hooked up a 10' feet piece of 1/2" pvc to the outlet of the pump water will shoot out about 15 feet! but the pressure will not go above 30-35lbs of pressure. I'm at a loss. I put in a few of these systems in the past and had no problems. Everything is new. Pump, check valve, and point. Please help!!

Are you pumping into a tank? What kind of pump are you using? Are you getting any air in the pumped water?

Pressure tank about 5' feet from pump. The pump is a Master Plumber model 123355 convertible 1/2 hp. There is no air in the water at all. I have had all connections apart a couple of times and can find any leaks.

The nozzle in the jet assembly is plugged. Take the jet assembly apart and clean out the 1/4" hole in it and then it will build pressure. Pumps don't build pressure, the jet assembly builds the pressure.

I would guess that the jet assembly was exchanged with the pump.
