Is it okay to use bleach in a pressure washer?

I'm going to pressure wash my house before painting it. Someone told me not to run bleach through my pressure washer. I'm thinking of using a deck sprayer to spray on the bleach/water mixture to clean the exterior of the house if it's not a good idea to run the bleach through the pressure washer. What say you?

There is an attachment for pressure washer machines called "Chemical Injector". It is good for all types of chemicals you might want to use with your pressure washer machine. Whether you want to add soap or bleach or any other type of chemical that would be the way to do so. Once you connect the chemical injector between the hose and the machine's pump and place the hose from the injector on the bottom of the chemical's bucket, you also have to put on the black tip into you gun, otherwise it wont shoot the chemical mixed with water.
