pressure washer chemical injector image

It has the ability to mix cleaner with the water spray. Would it hurt it to run liquid pre-emergent and fertilizer through it as well?
Answer
Your best and cheapest bet is to use a pump sprayer designed for agricultural use. They will have seals that will not be worn as fast by the liquid fertilizers. If you are absolutely dead-set on using the pressure washer, get a low pressure chemical injector. This unit will go on the outlet side of the pump so that the fertilizer will not be going through the entire pump. You will still wear your gun and hose out faster, but it is better than destroying your pump before its time. I'll put a source to a good video of a guy explaining downstream injecting.

It could be that the chemical strainer is plugged. Sometimes after using the soap it will dry and plug up the strainer. You could try pulling the strainer off to see if it will draw then.
Most pressure washers use a low pressure soap draw system. On the nozzle at the end of the wand you should be able to pull it back to make it go to low pressure to draw soap.
It also could be soap stuck up in the in the injector. You may have to pull the soap hose off to to clean that out.
There is really no need to call a mechanic, these systems are pretty straight forward and it should be an easy fix.
