Discovery loosing air pressure

[MustangMike]

If walmart kept a decent stock of disco's then ya id suggest it to.. but odds are ur going to be waiting at the least a week but odds are 2 or 3 weeks..

Imo due to the wait times id rather just track the leak down and fix it myself or replace the guage for 15 bucks for a better guage and a 4 day wait for the guage to be delivered vs the wait for walmart to get you a new disco

Thanks for the info guys.

As for the Teflon tape, can I use the white plastic pluming tape that I use for the pluming on my garden hoses? I believe that is Teflon tape.

I will try to tighten it down first before removing anything and see how that goes. If it doesn't work then you know you guys will be sure to hear from me again very soon!

Thanks again!

Have you called Crosman? in the past they have emailed prepaid call tickets to ship it in for repair.

One thing you need to make sure of is that the air tube has enough pressure in it to cause sever bodily injury. MAKE SURE THE PESSURE IS DOWN TO ZERO! After that you can fix any leak you find.

A degassing tool from Crosman is $14.00, but you can degas your Disco with a 10-32 screw 3 inches long (must be threaded all the way) .  Screw it into the breech plug slowly until you hear air coming out of the barrel, done check the guage, or try to dry fire.

I got good news guys!

And yes I did call crosman. They told me to check the fill adapter and gauge for leaks using soapy water, or if I did not feel capable of doing this task I could send it in.

Anyways, after tightening the valve was unsuccesfull I went and grabbed some high grade Teflon tape (my precious rifle only gets the best!). Removed the gauge and low and behold there was basically no teflon tape there in the first place So I rigged it up with some tape, pumped it up to 2000 psi and now it was leaking even worse! Oh NOOOOOO. So I removed the gauge again to check my work and the darn tape did not seat properly and just slide up the threads. This time I made sure the tape stuck in the threads and tightened her down nice and snug, pumpd it back up to 2000 psi, checked for audible leak, none. Now on to the soap test, no bubbles.

SUCCESS!!!

crosman uses something kind of weird sealer tape.. its not teflon tape almost like some kind of liquid gasket or something

[Ol'DeadEye]

Could the "liquid gasket" be teflon pipe dope?

I use the 'Oatey Great White Pipe Joint Compound with Teflon' in lieu of the tape for plumbing work because it's easier to apply and stays in place while tightening up without sliding/squeezing out. Only need a little bit, since pipe threads are tapered.

Teflon tape needs to be wound in the direction that tightens the wrap as it is threaded in....but it sounds like you learned that one the hard way.  You also start a thread or two from the end so none shreds off and fouls things.

Sounds like you are all fixed up now.

For future calls to Crosman if something like a rifle needs to go back ask for a prepaid call ticket to be sent to you.  Everytime I asked they furnished one for rifles.

I am sure you will enjoy the Discovery the low pressure fill and the performance of this entry level PCP will have you spending some $$$$ for higher end stuff very soon LOL

GecoGuy,
Even though this has been a bit of a pain to diagnose and fix, you were succesful and learned a lot.  That is BIG!  Next time you have a different gun that leaks you'll know how to fix it in no time flat.  People look at problems with the guns they buy in differnt ways.  Sure, it shouldn't have a problem, but somethimes they do.  If it is a fixable problem, and not something that is really broken, I always vote for fixing it myself.  The end result is the same as if I had returned it, but I always save a ton of time doing it myself and then can be confident in how it was done.  It's all about learning.
Just my 2 cents,
Lloyd

Thanks guys, I pumped the disco up last night to exactly 2000psi and what do I find when I wake up....2000psi 

So much better without that leaky air tank, now I don't have to pump it up every morning.
