removing pressure washer spill valve

I think what you are asking about is more commonly known as an unloader. It dumps water when the pw gun is closed, right? By dumping excess PSI, the pressure is regulated.

Did you find hte part in the pictures I sent to you. Do they show enough detail to determine if the part is threaded? This may be a proprietary part, only availble from Karcher or another PW sold by the same group of companies.

Do you have a local Karcher dealer?

Your Karcher is different than either of my pressure washers, so I am not familiar with the unloader on your machine.
