MItyvac problem

[Gaz62]

I recently bought a MityVac. It has been working really well and I was very happy with it but suddenly it won't create any vacuum at all no matter how much I pump it. I'm wondering if anyone else has had this problem. I've messaged the shop and am waiting to hear back. Thanks!

The quickest solution is to find where the leak occurs. You will need a bucket, sink, or bath tub to submerge just the cylinder, and the hose. Do not submerge the trigger pump. Seal the cylinder against your body, no need to fill up with water. Submerge the cylinder and the hose. If you use the water trap, submerge that too. Slow, and I mean very slowly, pump. Where there is a leak, you will see heading of ponding water. Once you discover where it is, we can assist with the patching or work around.

If you have left the trigger pump in a hot environment for a while, it may cause a seal to warp. Same for if you have water intruded into the pump, it can cause the seal to warp.

Hi oldandlively, Thank you so much for this. I will try it, although there doesn't seem to be any vacuum at all even at the end of the first piece of hose, so it is possible the problem is the gun itself. By the way, I have been doing dry pumping as its inconvenient in my living and travel situation to do wet.
Another problem has just emerged. I was giving it another go and try and identify where the problem might be and in that process the handle has fallen off! I'm having trouble getting it back on again due to the small metal rod that holds it in place.... Tricky! Any advice on that front would be appreciated as well. Thanks alot!

Ah, the trigger rod. This is the "slow and steady" to reassemble it. @DLD do we have the MityVac schematic manual for the trigger by chance?

I don't think so but I can see if Sheena can put online.

How's your approach on reassembling the trigger pump brother?
