burst disks ?

[Hammie]

Hi iv recently had a burst disk, burst on me I was just wondering what can cause a burst disk ?
The reason I want to know this is because I don't want to get it replaced if there is something else
Wrong with the reg, I would want to get the reg fixed first, cheers

Normally it is the LP 1.8k disk that pops.

A common cause would be dirt inside the reg (dirt trapped between the seals/oring/piston seat). Can also be the either of the seal/oring/piston seat has worn, or even a dry oring.

With the LP 1.8k disks. When replacing them, becareful not to weaken them (ie. bend ) as they are very thin. And try to use the disks from the same manufacturer.

When replacing, make sure you place the correct disk in the correct hole, 1.8k/7.5k.
