About a month ago, I installed a ball valve on my other inlet to help during starting. I use a cat 4sf pump. The valve is open and dumps on the ground while I start the engine(water is on). Once the engine is running for about 30 seconds at full rpm, I slowly close the valve and go to work. Before shutting down, I turn the engine down(water is still on) and I open the valve(water dumps on the ground) and I let the engine run for about 30 seconds at idle.
Yesterday while using for about 15 minutes, I heard a loud pop the engine died and water starts spraying out of every connection in my foot pedal. Go to the pressure washer and restart, close the valve and the pump hits 5000 psi and now the pump head is leaking(my pump is rated for 3500 psi).
I'm guessing my unloader is at fault and a pump rebuild is in order. I have a replacement pump to use so the down time won't be an issue. But did that valve I installed have anything to do with the unloader failure or is it a bad idea to use?
EDIT: Messed up writing this, the ball valve is on the OUTLET. There is water running through the pump the entire time the engine is running. sorry about that.
