Annovi Reverberi AR AR42118 Unloader Rebuild kit, Black

Worked great

My unloader had the o-rings go bad, and this was the quickest way to fix it. However, you should be aware that you should also buy a pressure gauge to get the pressure accurately set. It does not take that many turns to increase or decrease the pressure.I adjusted it first just visually against my old unloader. After I installed this, I quickly learned that I had the pressure set too high, and it would stall the engine. After setting the pressure to my machines spec's, I had no issues at all.Overall this is a great replacement, but make sure to have a gauge handy!

In general this solved my pressure washer problems and made it operational again. The problem it developed is that it wouldn’t switch to high pressure and only sprayed a low pressure stream. After installing this I have the same problem for the first few minutes of operation then it loosened up and works properly. Over time I have to wait less and less but so far I always have to wait if the washer hasn’t been used for awhile.

Was an exact match/fit for my pressure washer pump (rmw2.2g24) on my Troy Bilt pressure washer. It didn’t come adjusted the way I needed it so it took a few times to get it right but eventually worked great. If the screw on the end is too loose it does not get enough pressure and if it’s too tight it stalls when the trigger is released. Mine did not come with the screw to remove/install the inner seal so I had to find one separately.

Props to these guys for including a note about swapping out the valve seat.As other reviewers have mentioned it took about 5 minutes of loading/unloading before it loosened up and started working really well (the original was the same way in this Generac 3100/2.7 pressure washer when I bought it in 2013 or 2014).Pleased that this 30-some odd dollar part just saved me a pump replacement - over a hundred bucks back in my pocket versus the alternative.
