If a spider gasket is worn enough to cause a leak to waste, would it be obvious to visual inspection?
A little context: I have a leak somewhere in the plumbing, which is verified with the bucket test. I was hoping/praying that the source might be the multivalve as that is an easy fix. However, upon disassembly, I find no obvious wear outside of normal. Meaning, I can tell the outer ring of the gasket is slightly worn, but no broken or displaced or ragged spokes. Spring is a little sticky but seems to be working as intended.
I'm just wondering...the spider gasket costs $27...do you think it is worth it to replace it in a process of elimination, or am I chasing a ghost by focusing on the multivalve?
Thanks in advance.
