Major marauder problem

Hello everyone,

So after many months of using the hill valve in my .25 marauder I decided to treat myself and get the cothran powerhouse valve. I've taken the rifle apart many times to replace the o rings so nothing was new to me. after installing the cothran valve I started to fill the rifle up and I heard air coming out from the end of the barrel. so I tried everything. I replaced all of the o-rings again and put the valve back in.(not a big fan of the transfer port design) Same thing. so I decided that I would just put the hill valve back in and contact wicked air rifles on Monday but I still have air coming out of the barrel with the hill valve. Row remember, I have already changed out all of the o-rings. what could be the problem? any possible solutions and advice is greatly appreciated.

Thanks,

Matt
 
You have to fast fill. Meaning crack the tank wide open to force the valve closed. Just really quick give it a gush of air. Cock the rifle leave the bolt open and give it a blast. Watch you rifles gauge as well. Let us know what happens.

it worked! I heard air coming out all the way up to 1300psi then the leak stopped. appreciate everyone's help!
