Exped Synmat UL9 deflating

TIP: The online Bushwalk Inventory System can help bushwalkers with a variety of bushwalk planning tasks, including: Manage which items they take bushwalking so that they do not forget anything they might need, plan meals for their walks, and automatically compile food/fuel shopping lists (lists of consumables) required to make and cook the meals for each walk. It is particularly useful for planning for groups who share food or other items, but is also useful for individual walkers.

Exped Synmat UL9 deflating

Postby Suz » Fri 10 Feb, 2017 11:02 am

My Exped Synmat UL9 has taken to slowly deflating over a few hours. It has lost its green silicone flap that lines the inflation valve. Do any Exped owners out there think that may be the cause of the problem or am I likely just to have a small tear somewhere on the baffles? If it is tge likely cause, does anyone know if there is a fix for this?

That does sound like a likely cause for a slow deflation, you might have to contact Exped or their distributors to see if the flap can be replaced.

I think Mike is correct. I know that I have to be careful to not have any insulation fibres blow out and sit under the green flap when I tickle a bit of air out of my UL9. If the flap doesn't seat properly it causes a very slow leak. I guess that says the green flap is an essential part of the seal.

To try and find the leak just make up a brew of soapy water using dishwashing detergent and water.Filling up an almost empty detergent bottle with water and spraying it on the inflated mat should show where the leak is with a bunch of bubbles.

That or just dunk it in the bath, bubbles will come up from the leak and then you don't need to worry about cleaning off detergent to make the glue stick from a patch

thanks all.

Exped are sending me out a new silicone flap to insert in the valve and hopefully that'll fix it.

Need the little guy to keep me warm in tazzie soon :)
