Kiteaid Valve Donut Repair Kit

Used these donuts to stick valves back on and worked really well. On the leading edge valve I add some Tuff tape on top of it as well just to be sure.

These things are very useful for resticking detached valves - they'll save you from having to buy a whole new valve in many instances. They are tricky to work with, though, as they are just a very thin disc of adhesive sandwiched between two paper layers. It's especially hard to get the brown paper off without distorting the shape of the ring. Although it doesn't matter that much, because the adhesive is so squishy that you can just fold the excess back under the edge of the valve once you've got the paper off, before sticking it to the bladder.
