living with a very slow leak.

I hear a slight hiss when i stick my ear up to an uncapped valve on 2 out of the three valves of my Zodiac Pro. My valves are the semi-recessed variety, with the little green round thing on the top.

When I cap the valves, they leak very slightly, so that I might pump them up for a minute or two about once every three weeks. I made the caps less prone to leakage by winding plumber's teflon tape onto the cap threads.

Am I wrong to presume that these valves should not leak at all with the caps off? Yet despite the fact that I have tried everything to stop the hiss, including installing new valves, the problem persists. It is hard for me to get my head around the fact that, after all these years in business, Zodiac still builds an inflatable boats in which the uncapped valves are meant to leak a little.

Two questions. First, is this everybody's experience? Or do other RIB brands have better designed valves? Or maybe I have it wrong, and the cap itself is supposed to seal the valves?

Second, I have used Teflon tape and vaseline to some advantage in sealing the caps. Is there some other product or substance that will do a better job, without also harming the valves?

RTFM as they say! Perfectly normal, the cap with rubber O ring is the *final* seal.

If that's all you have to put up with, you are doing very well. On one of my valves I have to get the cap on fast, or the tube section will deflate.
