That Pop off Valve is rated for 6000PSI. It is very easy to adjust the Pop Off Valve to the pressure of you unit:

1. Screw the Allen head plug on the end of the Pop Off valve all the way in (clockwise) till it stops.

2. Install the part on your machine.

3. Turn on the water, Start up your unit, and run it up to full pressure.

5. Slowly unscrew (counter clockwise) the Allen head plug until it Pops off.

6. Shut off the unit and turn off the water

7. Turn the Allen head plug back in (clockwise) 1/2 an turn

Now it should be set for the pressure of your unit. If it Pops again you might have to give at an extra 1/4 turn (clockwise).

Water Cannon have the solution :

This problem was most likely caused by any of following:

Freezing - Always drain the excess water if there is a possiblity of a freeze

Try using our Pump Saver product

Cavitation (low water or no water Condition) - Increase the size of the garden hose

Try using a 5 gallon bucket to test the water supply - Always avoid using the dish washer or washing clothes if a pressure washer is in use

  

Over Pressurization - over time bypass pressure unloader valves can be over tightened

You can test for over pressurization by installing a pressure test guage and triggering the trigger gun to se the pressure spikes

You should never be more than 10% over rated pump pressure when the trigger closes.

Never use regular engine oil

Be careful not to overfill your pump with oil and always use the manufacture's recommended oil brand or a 30 weight non-detergent oil.

Never use regular engine oil in a pressure washer pump because the detergent will cause the oil to foam up and leak out the top dipstick. http://www.watercannon.com/default.aspx
