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.

That sounds like the issue.  I did not see a spring (maybe it rusted away).  When I put the ball back in (NO spring) shouldn,t  there be a draw?  I am thinking maybe the spring rusted and is blocking the path to the water stream.

I can't find a manual online for it... some people say that it only sprays in low- pressure  selection... (does it have two settings?)
