1901-0 Craftsman Pressure Washer - Overview

The description of the parts package on your website did not appear to be in proper (size) scale However, after following a Youtube video, I was then able to decipher what parts went where to be sure I was ordering the correct parts that I needed. Parts were shipped promptly and I found that replacing just the check valve o rings and seats, it cured the problem without having to use the other parts that came with the kit package. Would definitely order from this site again. BL NC

One can either pull off the plastic fitting on one end (the one with an o-ring) and press the plastic tubing onto the pressure washer detergent inlet (located just behind the high pressure hose outlet/connector). The other end of the device is then inserted into a jug of pressure washer detergent and the lowest pressure nozzle or nozzle setting selected to allow detergent to be drawn up into the washwater stream with the pressure washer running. One can observe the detergent flowing into the washer if all is good! If one cannot pull off the plastic fitting on one end (the other fitting, to be left!, has a "screen" on its end - the fitting can be cut off the plastic tubing with a utility knife.
