hey, i have heard that qev's are very sensitive to drops in pressure from shrader valves when diconnected after filling, and i was just wondering if a quick disconnect has that problem? if it does then i would need to install some sort of check valve, and does anyone have a link to some small, compact one?
EDIT: relised that it was a quick disconnect, not release. *duh*

I don't know about the pressure drop generated from disconnecting a quick disconnect hose fitting, however, putting a ball valve between your valve/chamber and fill fitting (rather schrader or quick connect) will solve the problem. Simply turn the valve off before disconnecting the hose. In many cases, the same valve can be used for piloting the gun.
Hope that was kind of helpful.
Peace,

ya, im going on the safe side and using a check valve, and plus i havent seen anything about not needing one.
also, i would usually use a ball valve, but i want my gun to be as clean as possible, no levers sticking out for me.

There are rules, and then there are hundred dollar bills.
I've recently had the problem of both a presta and schrader valve messing with the QEV.
A ball valve locked before detaching the pump connector head or a check valve both worked perfectly to fix it.

i think im going to go with an inline check valve...i dont really want to have to deal with the ball valve.

i mostly did the south island (went with my dad), we rented a campervan in christ church and then went from there to franz joseph(sp?) glacier...then we went up the coast and into..uhhh...whitianga ( too many maori names for me..never could get em strait) we then went to picton and took the bluebridge across into wellington and then drove to lake taupo and fished the big river near there... then went to Rotorua and then finally into Auckland. the south island was very quiet driving and all in all i loved the country ( total time was about 3 weeks, not enough tho)

I live in Auckland myself, but only been to the south island once.
