diaghram wont seal

[jon_89]

i got it to work once and it was with my shock pump. i over pumped it and it burst but i cant remember what i did?

How close is the phram in size to the id of the pipe. Get the gap really small. like under a millimeter

Ever made a diaphragm valve? You obviously have no idea what you're talking about.

Jon89, pictures would help a load. The diaphragm itself is probably fine; getting it to work relies on patience and how you set it up inside the gun.

[jon_89]

so what is the best set up?

[jon_89]

i got it to seal now but air is not getting in the chamber. i have a small hole for eqaulization.

That doesn't make sense. Is the diaphragm inside a union?

[jon_89]

no it is in a female adapter and a plug.

[noname]

Then how come air can't flow around the diaphragm into the chamber?

[jon_89]

i have no idea thats why i am asking.
