Hi-rider leak

[Heino]

One of the hi-riders on my Zodiac MK6 is leaking.

The base of the valve seems to be seated to the material. I tried sealing from the inside by filling up with SikaFlex. Tried twice so far but no luck.

The best may be to cut it out I think and gluing in a new valve. Is this possible or are there any other options.

I attach 2 photos. Please let me know any ideas.

Sikaflex won't fix anything like this, although you can do clever things with it (run a thin bead down a seam to help form an angled curve, then patch over it for seam leaks).

The valve has a gasket inside it made of neoprene. Part number is Z3001. It should be replaced every 5-10 years. If you have a metal valve, it can be cleaned in an ultrasonic cleaner with vinegar for descaling.

This is a plastic valve. I cant see any place to take it off. Seems as if its sealed to the hypalon fabric.

Is there perhaps a thread or guidance on how to replace the neoprene gasket.

Thanks

Also, the valve seems to be seated into the material. Is there a way to unscrew it or does it have to be cut out and replaced.

Thanks in advance.

It's seated in to the material with age! Unless someone did glue it in afterwards.

That big nut should spin off, then you'll see a threaded tube protruding. Push that tube the internal portion with the protruding threaded tube falls in to the tube set.

Then you'll have to scrape off the old gasket and replace it with a new one.

I had to cut the valve out at the end. Even with the valve out, the bottom section could not be unscrewed.

Will go to the Zodiac dealer and get a replacement hopefully set in a piece of hypalon. Then glue it into the spot where this one was cut out. I hope this will sole the leaking issue.

See photos attached - hope I made the correct choice here!!

That is probably going to be a challenging fix on the speed tube.
