I got my SSPB the other night and decided to plug the OPRV, so I did. But now when I pump it doesn’t actually pressurize, or whatever you’d call it. Although I did get it to once after I plugged the over pressure release valve… but never since then. I already tried putting e-tape around the plunger head, under the o-ring and pumping quickly (fast strokes.) So any help would be appreciated.

Since you mentioned th you got it to work once before, it sounds like you burst the valve, by overpumping.

You've probably plugged the valves that let air into the pump chamber. These are one-way valves that let air in, but not out so you don't want to block them. Try taking off all the glue (scrape it off, use tweezers, whatever works). If there are multiple holes, plug the one in the center. Can you get pictures up to see if there are any cuts, because if you cut the plastic to get to the pump, that's not good either. The membrane that is the air tank could also have burst if you put in too much pressure.

I don't believe that the valve popped. Because I got it to pump, so I pumped it 3 times. then fired it. Then it wouldn't do it again.

Where did you make the cut so you could get into the pump chamber? You might not be pumping it in a straight enough manner. Mine has that propblem some times.

Exactly. If the valve or tank membrane popped, then it would be impossible to do it again. Hold your finger over the barrel to see if air comes out and pressure builds behind it. If it does, then the valve is trashed. If it doesn't, then the pump isn't working or the membrane has popped. Pressing the trigger with your finger still blocking the barrel will help you decide, because if pressure builds, then the gun works or the membrane burst and does not work as well as it did. If nothing happens after pumping, blocking the barrel, and pulling the trigger, then the pump is shot.
