I hope one of you can help me. I recently replaced the water inlet tube on my power washer it was cracked(plastic) Before I took it apart other than the obvious problem it ran well. there is a tube on it that can be used to suck soap into the water supply for washing cars ect. it only does this on low pressure setting. Since I put it back together the leak is fixed but the water now flows out of the tube designed to suck and of course the pump runs constantly because it senses a water leak(no pressure) It appears to be a water valve problem is there a certain way to put them back together it appears you can put them together three ways. Hope somebody can help.
