Edit: This turned out to be a Crosman 1400
What would most likely cause a B392 to not build pressure with pumping?
Worked great for many, many years then SUDDENLY would not build pressure. Happened all of a sudden.
Where would be a good place to send it to have it fixed?
Thanks in advance. |

| Seals/O-rings. They often need some love in the form of non-petroleum based lubricant. |

It seems worse than that.
It went from pumping just fine to complete failure to hold any pressure at all while I was using it.
Pretty sure I tried to lube it. BUT I will try that and see what happens. It's been sitting a few years since it happened.
Let me 'come clean' here.
We had a big problem with black birds roosting and I used it to scare them away. Pump, pump, pump...bang.....pump, pump, pump....bang.... over and over with no pellet in the barrel. Many days in a row. |

| Dry firing a pneumatic should not damage it. This is only a problem for springers which rely on the pellet to cushion the piston. |
