Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a McCoulgh pressure washer that has stopped drawing solution.  I took the unit apart and cleaned the hoses.  Basically there are two hoses from the solution tanks (there are two) to a control value and then one hose from that to the outlet.  I assume the pressure from the water going through the outlet produces a vacuum that draws the soltuion in.  I tried to directly hook into the input vavle and it still did not work.  I took off the input valve and cleaned it.  Basically it is a valve with a barded part to connect the hose and then a ball bearing inside.  Is this part replacable?  If not is there another way to connect the soltion tanks.
