Searched around the forum for a bit, but couldn't come up with anything.

I just received a used Karcher M20 electric pressure washer. I was under the impression that the previous owner had somehow clogged up the detergent feed valve (I was correct), so I disassembled it to repair.

However, ran into a huge problem - I lost the little metal ball in there!!!!

I located its OEM replacement HERE (http://www.pressureparts.com/Pressure-Part-7401909.aspx), but cannot justify $5 shipping for a $1 part...not to mention the fact that I want to use it ASAP.

I tried looping/blocking it off, no dice. the pressure is too great and destroys any vacuum caps or hoses I try.

For a reference, I am talking bout this little guy:

Does anybody know what size that ball is, and where I could find a replacement other than online? It looks as thought it would be larger than a BB, and definitely would not want to risk that chewing up the motor.

Thanks in advance!
