I have a Ryobi GCV 190 power washer. Recently I decided to use it to power wash my house which has vinyl siding. Over the past decades from when it was installed, it has become dingy with green growth on the shady sides. When I used the power washer on the one-story garage, the soaping setting on the nozzle worked as expected. When I added a 35 ft. Ryobi hose extension, it did not pick up any cleaning fluid from the reservoir. When I switched back to just using the original hose alone, it picked up cleaning fluid as before. Is there any remedy for this?
Welcome to the forum.
My speculation is that the added hose increases the pressure, preventing the venturi effect from drawing fluid.
Is there a less restrictive nozzle available for using when adding the extension hose?
