Tuning RTI Prophet Performance has a leak ( somewhere )

[jdanvers]

Not a fast one. Say I fill it to 250 bar and shoot it down to 200 ... it'll drop to 150 after about 4 or 5 days. So its not a show stopper of a leak but ... it is leaking ( wasting ) air. As you can see i have it looking kind of like a clown now with a couple of ballons i just attached to both fill ports. I just attached them ... I'll check on it on a day or two to see if either one has started to inflate ....

If not ... ideas / suggestions as to where else I might look / try to figure out where it's leaking?

I had a similar problem with a Daystate MK4. Member suggested Snoop leak detector. Found leak immediately. Soap solution didn't work.

Maybe add one on the reg body, and make sure the degas screw is snug (through buttplate, below hammer spring).

Pull the shroud and put one over the barrel. ......Unloaded and with the bolt closed.....

 

[jdanvers]

@orchidman - thank you. If still a mystery after a few days then perhaps I'll shop and find some of that stuff.

@scotty1 - ahh ... yeah. That could possibly be the culprit. I did get this reg swapped out under warranty and did degass it prior to pulling it apart ... thank you. I'll be check / double check that I snugged it up. 

@jasonmc - thanks. Unloaded. ( "pew!! Hey there's a big hole in the balloon I have at the end of the barrel!" lol )

CHECK GAUGES AND REAR AIR FILL SPOT

Sell it and get an FX, they never leak.

JEST.



I would quite like an Impact.

Soapy water would work better. Mine leaked around the rear foster attachment. Also check your reg gauges and foster. Spray some soapy water on there and watch for bubbles to pile up.

A leak detector applied via a dropper will show even a very slow leak. As the liquid clings and bubbles up much better than soapy water.

The dropper helps apply the liquid accurately where you want it.

Harry just about killed me I was laughing so hard about buy a FX gun they never leak...

The reason I own a Prophet and I am sucking up and thinking about the new Prophet 2000 dollar compact is there built simple, And leaks are very very few for the guns sold,,, So I am watching this post and hopping its a simple and easy fix,

I use snoop at work to leak check pneumatic fittings on aircraft. It does work better than soapy water and, if my memory serves me correctly, it is non-corrosive.

Winner! Winner chicken dinner!! Those who said guages - ding! ding! ding!  

Reg guage was *very* slowly seeping air - soapy water helped me find it (finally). I gave both if them a slight turn of about an 1/8" of a turn to snug them up. I've been shooting it ... need to fill it to 200 or so bar and just let it sit for a few days but I'm hopeful that I've (we've collectively) identified it.

 

[Joedirt199]

I think they worry more about clocking them so they look nice and straight from the side. I just snugged mine down tight and don't care if they don't line up. Hate leaks more than crooked gauges.

Douger for the win! Give that man a tin of Piranha pellets!

I am having a similar problem with my RTI Prophet Performance .22 leaking air over night. I'll shoot it. The next day when I take the gun out the gauges read 0. It takes an air tank to put enough air in fast enough to seal what ever is causing the air leak. I am wondering if the hammer spring adjustment would cause something like this to happen. By the way, the air is leaking out the breach. Cocking the rifle a few times will be enough to stop the leak. 



Any help would be greatly appreciated.

DJ, it's got to be the Poppet, it may need cleaning or resurfacing, I've done a Burnish with a drill and a soft cloth and a little oil, it worked on the Peek Poppet on my Brocock, or you could replace the Poppet

The one I had leaked between the regulator and bottle. I put a large zip lock bag over barrel, taped the small holes on pressure gauges and hole on top of regulator then dipped the gun carefully under water barrel first in bathtub as to not get trigger wet etc. It was a very small leak that I was never able to fix. I had went through 4 different factory regulators and replaced the orings never did get it to hold air. Long story short I got rid of the gun best fix ever imo.
