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.
