Hi
Im using 2012 12m model and after about 10 uses I noticed the leading edge deflating due to the loose fit of the inflation valve plug, Its supposed to be a one way valve but does not work well at all.
I can try wrapping tape to snug the fit, any other suggestions?
I wanted to hear from any one else having this issue before I make a complaint to Epic about it, as this needs to be sorted.
Oh how I miss the Naish inflation valves.
Cheers
... my guess is that its not the loose plug but the valve delaminating from the bladder. No big deal, grab a stick on valve and replace it. It'll take 10 minutes. I recommended the North stick on valves which are over sized and after 2 years we've had no problems so far. Its pretty easy fix!
