Silca Tattico letting air out of the tire when removed!

I had the same problem and it drove me crazy. It now lives with my Brompton and only gets used on Schrader valves (the chuck is reversible), on which it works great.

It strikes me as strange that some folks clearly have this problem and others do not. Just wish I was one of those that wasn't.

Just for the sake of completeness, here's a video that shows the problem I was having and my eventual solution (inspired by jbay's post):

LOL. Nice! I’m glad I was able to provide a little inspiration.

A little grease on the o-ring inside the head has helped me with other pumps in the past

Interesting..I screw a Schrader adapter on one of my valves and leave it there in case my pump fails and I gotta go to a gas station. Alloy, weighs not much.

anyone ever find a fix for this? I also "upgraded" my pump from a Lezyne road drive when my Road drive broke after 3 years of service.
Imagine my disappointment in the Tattico after I pump up to 80 PSI and I'm lucky to have 60psi left when I try to remove the head.

I am still getting my head wrapped around a mini pump with a bluetooth pressure gauge....

posting an update. with practice, I managed to find a sweet spot to use this pump without much air loss. I put some engine oil on the o-ring first. When inserting the presta valve, I just get one thread in before locking the head. I pump till desired PSI and now in a quick motion, it loses 1 psi when I remove the pump.

I like the wax...but for the most part the Silca name is getting ruined by a number of poorly designed, expensive accessories that fools like me have been dumb enough to buy. Disappointing.

Yep, here's the fix:

Nah... thats just a work-around. I would love it if it would work as other users say where they can unlock the lever and not lose any air.

Ha! Good luck with that. Maybe on an unthreaded valve?

this, lubricate the hole.

Somehow the head is pushing on the plunger. This can happen with all presta pumps, but maybe the Silca is worse/shorter? With most pumps if you make sure the plunger is free, it won't happen. Maybe you can drill out the schrader side of the head and it will improve. I understand when a pump is designed for a high sales volume, but Silca ruining their pump for the vanishingly small market of people who intend to sometimes use it with a Shrader valve doesn't make much sense.

Attention conservation notice, tl;dw a Schrader adapter. If you want to see the Schrader adapter in use, it starts at 2:28.
