Tubes deflating

I purchased a year old 2008 demo Ribeye 6 Meter, which I recieved in perfect condition. however a year later the tubes are continually deflating after about 1 month. I hand pump them to the max. I have tried the soap and sponge to see if the valves leak, no, and they all deflate together!! Tried for holes in the tubes, nothing.... would appreciate any help please...

Sounds more like the ambient temperature affecting the tubes rather than a leak.
For all the tubes to go down you'd have had to blown each baffle that separates the chambers.
How flat do they go?

Oh and welcome to the forum!

As Chewy says, it's probably the temperature. I went to see my RIB the other day (also a Ribeye) in it's dry stack and the tubes looked very flabby - however I know that once the sun is shining they will be as firm as a.... better stop there!

I would be careful not to inflate to a level where, once they do warm up, they become overinflated. I don't think the valves self regulate (but am not sure).

...and welcome from me too!

All wot Chewy said, and I'd ask: 1. What colour are the tubes? 2. Do you store the rib uncovered? 3. Do you store the rib in a sunny spot? 4. Do the tubes stay deflated when in the sun?

Or could be some sort of issue with the valves. Are you sure they are "closed" and screwed tightly?

I have seen a couple of times the valves not closed properly and this would cause a deflation but I would expect them to show reduction very quickly. Tim has said check valves which is easy on your tubes and then check the hose fits neatly which should tell you valve OK. All the Ribeyes I have been using have not shown your problem from new to the older ones. I guessyour 2008 boat has release valves also? Heat affects all if left for some time in cold conditions they all loose the firmness.
Did this just start to happen this winter or over another period?

If all else fails I can pm you a contact name and number at Ribeyes to help you
