but when we place the inner plug properly isnt it actually doing what we are saying, closing off the top of the open slits, if so then maybe they arent the main issue and only a little seapage or spattering is happening in that case.
i will test this, cut a few in half and fill liquid up to where i cut it and see if it leaks, if it leaks then its the base where the stem meats the base, if it does not leak then its form the top of the stem????? or if it does not leak then it doesnt leak, i dont think it has 2 issues with leaking
cut a few in half
? so many? Yes, the inner plug should close them off, but I don't have a picture of how much of the slots get closed off, and I don't have a ceramic cup on the loose yet, the cartos are working great.

I killed the carto. Sigh, next time I listen to you all! On to my 3rd cart, had them about a week and a half? I don't remember, but I stick to only one cart all day, no rotating. If I quit screwing with them they'll last forever I'm sure lol
