Toilet does't hold water

[Flygal]

EWWWWWWW a poopsicle

Many of the blade seals are double-lip and the blade goes between them -- Clean the INSIDE between the lips with a popsicle stick or tongue depressor, wood with rounded edges so the seal isn't damaged -- I would put some silicon grease (dielectric grease if you can't find the plumber's silicon grease) on the seal and blade to lube and protect.

Do NOT eat the stuf you may find in the seal...
