Camping mat deflating
Hi,
I have a Silentnight, double camping mat that has a foam core and standard valves at the bottom two corners. I bought my first one 3 years ago and after 2 years it wouldn't stay inflated, so I bought a new one. I've just got it out to get ready for camping in 2 weeks and it won't stay inflated.
I've inflated the mat and put the valves in water to see if there are leaks, nothing. I've inflated it and wrapped the valves in cling film and gaffer tape and it still deflated. I can't find a hole in it either.
Does anyone have a suggestion on how to troubleshoot this or an alternative mat to buy that is cheap but reliable.
I only camp 3 times a year so I'm baffled at how this has happened. I used it 3 weeks ago and it was fine. 🤷🏼♀️
