After 20 years, our rolling diaphragm has given up the ghost in Schnellkochtoptdeckel. Since the pot is otherwise still intact Fissler I've been looking at Amazon and have found it. At the membrane, I also like the sealing ring (item number is in the ring) sought and also found. Both ordered, delivered and installed as soon as possible. The pot is like the first day. No dodging the steam more quickly and he builds decent pressure on. The investment has paid off.
