I was spraying away and all of a sudden the pressure dropped and started dribbling!! I was gettin down towards the bottom of the tank, but not completely empty. So I went back and refilled and went back out and I couldnt get the sprayer to prime. ANY IDEAS??? I took off 2 of the 3 diaphrams and replaced them and checked the o rings, but still no luck. Maybe its the diaphram next to electric motor. It is a hypro D403 pump. THanks Could it be the valves??

Ever checked the filter? It does pick up a lot of junk sometimes.

Yes I clean the strainer daily. Has anyone replaced valves on the hypro D403?

Unless the inlet hose is blocked, its likely your relief valve. Pressure follows the path of least resistance, so when the springs and seats in a pressure relief valve are weak it will send back all the flow to the tank (or in the case of some space savers) recycle it back to the inlet.

Check for that. If that is indeed the problem, you need a new 9910-GR40 regulator. I know a fantastic website that has lots of them in stock ;-) .
