[singularity]

i got one of these a little while ago

just recently got around to puting it in only because i had a working one already on the gun (why fix something thats not broken). i pnuematically modded (this is the third or fourth valve ive modded, all the other ones i have work fine) well any way it doesnt seal, it just lets all the air out the barrel. ive been using a 25hp aircompressor to fill it. i took it apart again and realized the part of the diaphram that makes the seal i made out of some sort of hard plastic, did it dry out or something? so any ideas on how to fix this? o yea i forgot to mention its not just leaking out the barrel, its dumping all the air out the barrel.

The bleeder vent open? I got one from bcarms.com allready modded, it's just like yours in the picture, and my bleeder lever is flipped down, or up, ok it sticks out to the side. The solinoid was also removed and the hole epoxed shut.

well i epoxed the hole shut because i thought that might have been the problem so it sholdnt atter which way the bleeder is. i would have just bought from bc arms but my parents dont trust the internet or something, that how i got into all this (by this i maen building weapons) in the first place. i wanted a particlular weapon that was on a website by my parents wouldnt let me buy it so i built one

And they let you keep the one you built?

thats the story of my life
check if the valve is on the threads the right way thats my suggestion

Take a picture. The QC on the watermaster hasn't been good lately. 5 out of 7 I bought had problems with the hardwhite portion holding the neoprene sealing face. Used a box cutter to clean it up so it made a good seal. 2 of those were too messy to salvage so they went straight back to the store. They wouldn't even hold back water.

well i pretty much gave up, besides i once again failed at fixing something that wasnt broken. i had a nice working valve on the gun already, i dug it up from my back yard its about 7 years old, and its the only valve i have that hasnt given me any trouble(now that says something about quality). i did notice the hard white plastic part looked pretty beat up on the new valve.

Sounds about right. I've totally given up on that valve type.
