[modification] any way to stop flow when pump not on and no handle?

Hi all, I’m new here.

I’ve just started to get serious on pressure washing here in Finland, owner of a window cleaning company.

I have a DIY project which needs only the nozzle and hose from the pump. I would like to bypass the handle and trigger. So my question is to you pros here: Is there a way or equipment that would allow me to control water flow with only switching power on and off for the pump. And in a way that water flow through the pump would stop also.

It is difficult to explain this. Let’s just say that I’m attaching a stripped down small pressure washer to another machine and need to automate the process.

Thanks all, feel free to ask more info. This will be interesting project and I will share the result here soon. It’s a robot!

Electric pump with remote will stop and start pump. Not sure how you would stop water incoming flow completely . I’ll be in Sweden in Dec so hop over and say hi.
