Hi all,

Wondering if anyone out here knows of a pressure washer/ jet wash that you can adjust the PSI / bar on the jet wash itself and not by using different nozzles? I want something that I can dial up or down when I want. This is due to the attachment I a, wanting to use and I can’t change the nozzles on them.

Many thanks.

All pressure washers can be adjusted  withe the uploader,  it looks like this photo and usually is fitted to the pump

Thank you very much

My petrol jet wash has a Engine speed throttle. ( show a picture of a tortoise and hare).

Will this adjust my pressure or just cause stress on my engine?

Thanks

My pressure washer has this silver nut folllowed by a spring. If I loosen this, will it reduce the pressure?

Thanks

 uploaders  usually are spring activated so yes but that’s a unusually design, can you take a photo of the full pump head to show where the bypass is fitted

Yep that spring is the pressure relief valve, unscrewing it should lower the pressure.  as it bypasses through the pump head you need to be careful not to over tighten it when you want to increase the pressure back to full power try and measure where it is set now so when you screw it back you go to the same place
