Taipan Calling Taipan Pros

Hey those folks with taipans. I have an issue with my veteran 2 tactical model.

I have had it about a month, and shot a couple tins of slugs through it. So maybe 300-400 shots with some different pellets thrown in for good measure. I forget the count per tin. So it’s pretty new.

I noticed the past few days it’s losing quite a bit of air overnigh…it seems to stop losing it at about 100bar. I put a balloon over the barrel overnnight and it was deflated, so that’s not the leak point.

I’m thinking about taping a balloon to the fill probe foster end and installing the probe to rule out a stuck check valve.

I’m hesitant to use soapy water on my new rifle, but will if that’s the preferred method…

Any thoughts on spots to check next?
 
The first place I check on a gun with a fill probe is the fill port. Especially if a guy fills the gun using a bottle. If you fill too fast you’ll cook the oring in there. It also only takes one piece of lint or debris coming in that port to cause a leak. That’s why with all my fill probe guns, I leave the fill probe in and cap it.
I recharged the gun and left the probe in with a balloon on it overnight, no leak at the fill port, I guess that leaves the regulator, guage, or bottle to pressure tube union.

I was unaware that filling “too fast” could cause an issue with that oring. That said, from a pressure loading standpoint and not wanting to just hammer a massive increase in pressure into a gun I’ve always tried to crack valves slowly out of caution. The SCBA firefighter valves suck for filling guns though with all their little “safety stops”, so I can’t say I’ve had perfect control with the things.

The first time I used my omega tank and valve I was like, yeah, that’s why people go this route…super smooth and easy.

How fast would you consider “too fast”?
 
Taipan didn't change their gun too much from the gen 1 version. fill it to 230 bar or so. unplug the fill probe as usual. now put your ear up close to the breach, hear anything? if not, then partially cock the lever to pull the probe out of the breech. if you hear air escaping, the valve seal or adjacent o ring has failed. If it's quiet, move to the bottle attachment and fill section and reg vent section by plenum. If the leak is not back by the valve seal, then it's before the reg section. gun only has about 8-9 o rings I'm guessing. since the original had 6-7. You should hear it leaking when it's pressured up, if not, it's most likely the valve seal, which you will hear when you open the breech section by partially cocking the lever, you will then easily hear the air escaping.
 
Just use the soapy water. It's not gonna hurt anything. Wipe it down when you're done. God forbid if it rains on your Taipan.
😉
Good point, I don’t think twice about chasing a squirrel in the rain… it’s kind of funny that I would have an issue with a spray bottle and soapy water.

The ”safety stops” on your bottle valve are easily defeated by simply tightening the nut on the center of the knob

Alright, I am not certain which seal was the problem, but judging by the bubbling locations it was either the manometer/guage seal or the one that mates the bottle section to the standard air reservoir. Of course the taipan “complete” reseal kit was missing more than one size Of orings. I actually replaced the under guage oring with a yong heng green one I had in the tool bag….nothing in the oem kit was the correct size for that one.

I also replaced the main tube seal, bottle seal, and the small o-ring immediately inside the bottle just for good measure.

It appears to be holding air good now! My money is on it being the gauge seal, it looked pinched and somewhat dryer than how I assemble things- lots of silicone grease when replacing o-rings Is my preferred method.

Sounds like you had the same issue I did on my Tact 2, gauge o-ring was all buggered up and leaked. When I removed the bottle, that o-ring was not put on correctly either and needed replacing. Fortunately I had an o-ring for the gauge the would work on a temporary basis until I could get the correct one; The bottle o-ring wasn't leaking for some reason (it was really bad), but I had one to fit it as well. I've now got every o-ring they show in the schematic. I thought it was just my bad luck, but now, since your post, I'm wondering if there's a pattern here.
 
Fill it up to 250bar and see if you have the problem. Mine did exactly the same and I had filled it up to 275 bar which is what seemed to cause the leak. I did both the soap and the balloon with no air leaking. Now I fill it to 250 and have no leakage at all. I've had it stay at 250 for a couple of weeks so I know that was my problem.
Yeah, I was reading up on folks preferring 250 bar over 300. So that’s what I was leaning towards switching to. It held fast overnight…now if I can just keep my compressor running I’ll get back to shooting it! -an alkin can’t come fast enough.
