Know anything about the RX-20?

[Brody Robert]

Just dusted off the old RX and it's still working pretty darn well but it makes a squealing sound when I hold the spray lever.

I've cleaned out the water strainer and all the jets and added grease.
I've also read the manual and can't figure out what the problem could be.

Any thoughts would be great. Thanks.

Maybe it is just happy to be back on the truck.

Or, could be the valve plunger is vibrating a little in the handle.

It's a dinosaur crying for other dinosaurs.

I'd go with Stephen's deduction.

I've got lots of RX experience but can't recall your situation ever happening. If it's not affecting its performance, I wouldn't worry too much about it--new valves are not cheap. Probably just annoying, eh?

Haha. That was a great answer. Ok, I'll have to look where the valve plunger is.

Ohhh. Poor Tami. I'm glad you're not here to offend her. She's been such a trooper through the years.

No, it doesn't seem to be affecting performance but way way annoying. I feel like I need to oil something. Is there anything between the spray lever and the jets that I could oil? Lol.

 

[Steve Lawrence]

It's easy to take the cover plate off so you can maybe see the problem or at least tell where the sound is coming from. Maybe you just need to tighten the valve assembly.

 

[Andy]

do you have check valves on the spray tips? They can make a noise like you are hearing.

Loose nut between the cord and the handle would be my guess....

Last time I dusted off my CMX-20 it dripped water out the weep hole on the rotary union... Then I broke the head trying to take it off the wrong way.... I fixed it from when I broke it but it's been collecting dust most of the 25 years my parents had it... It did work for those 13 uneven corridors 300' long... This was before the Zipper...

Should have used the Powerglide.

When I need Roxy, nothing else comes close. I did an "annual" Pizza Hut thurs nite after a brutal turns week.

I used Saiger Red and just ripped the grease off like hot butter without a sweat.

Haha, Richard aka Desk Jockey, gotta justify those price hits somehow!
