Where does the detergent siphon hose connect on the pressure washer?

detergent can only be **** from the container only on low pressure.

Most detergent injectors work by the venturi system. That is that the detergent is drawn into the stream by the forward flow of the water thru a very narrow port after the water passes thru the pump. This system works best when the pressure at the tip of the wand is low. Trying using a very large tip to draw in and apply the detergent, then remove injector and rinse with high pressure. Not good for the pump but to apply soap reliably under high pressure the soap needs to be injected through the intake of the pump. enjoy

Yes take it to napa auto parts and they can cut and attach a new end which are for hydraulics. They are crimped on and meant to hold very very high pressure. I used to use a pressure washer everyday for a living and it was a tractor rental/repair shop and we used the hydraulic fitting machine on the power washer hose all the time so rest assured.

if you follow the chemical hose back to the pump it will be attached to a barbed nipple, behind the nipple there should be an o-ring, spring and a ball.
A lot of the time if you are using the proper nozzle in the low pressure setting and still cannot create suction the ball will be stuck to the o-ring. You can just free this up and put a little white grease on the o-ring.
