Leaky Stans valve
If the leak is at the base of the valve it could be you’ve damaged the sealing tape somewhere around the rim, so as you add air it goes through the damaged bit then the pressure drives it out the only place it can escape – the base of the valve.
Don’t ask me how I know this. Ahem.Posted 5 years agosmcicrMember
Weirdly I’m having exactly the same issue. I’ve checked the tape, all looks good, the tyre goes up but then deflates over time. The air is coming out around the valve – not from the valve.
Stans tape, valves, Flows.
I’ve stuck tubes in now as per the instructions – what? If I followed instructions first time this wouldn’t be my forum of choice now would it? ;D
I’ll see how it goes tomorrow when i take the tubes out.
Any tips on valve installation other than the grease – is it as simple as jamming them in or is there more finesse / technique to it? 🙂Posted 5 years agoNorthwindSubscriber
Don’t overtighten it, is the main thing- if the plug deforms it can open up a hole (or pull right through the hole in the rim!)
Also, really be sure you’re following the instructions 😉
One thing that nobody seems to mention is that if you have a hole in the tape anywhere around the rim, it’ll let air (and sealant) into the rim bed, which will then come out at the valve hole. So leaking at the valve hole doesn’t neccessarily mean a problem at the valve hole.Posted 5 years agoJolly Green GiantMember
I had a similar problem once. It was a slowish leak that I eventually traced by sticking the wheel in the bath to identify the source. Reseated the valve by sticking a small piece of insulation tape over the valve hole then pushing the valve through to form a better seal and adding more Stansted. Has been fine ever since. As North wind says also check the whole tape for holes and reapply if need be be.Posted 5 years ago
