Annovi Reverberi Gymatic 3/B Unloader Kit With Adjustable Injector – AR20400 Replacement

Fixing your pressure washer?

Here's an unloader kit that fits the Annovi Reverberi Gymatic 3/B pumps.

It's made by The ROP Shop, part number 100227_1.

This kit includes the unloader valve, an adjustable injector, and the bolt set.

It's essentially the AR20400 replacement.

Made from brass and other materials, it's built to handle the bypass.

No assembly required—just bolt it on.

Comes with a 1-year warranty.

If your washer isn't building pressure or the bypass is stuck, this kit will get you back in business.

Quick note: California Prop 65 warning applies for lead and phthalates.

But if you need to fix that pump, this is the part.
