Take the 2-minute tour ×  I have a slow-filling cistern and,
having disassembled all the pipes inside I've identified a
ripped seal. Assuming that I didn't cause that myself just a
moment ago, I'm hopeful that replacing it will solve the
problem.  Can you identify it?  Image of seal in my fingers,

used google image search. I cropped the image and searched by
image. I don't have an encyclopedic memory of seals.
