Review on 🚽 Sloan C-100500-K Flushmate Cartridge Replacement for 500, 501, 501A, 501B, 503, and 504 Series Flushmate Tank System (1) by Andrew Agarwal

I ordered this simply because it was delivered quicker than a Sloan branded replacement. Doesn't work as well as the original though. This thing has ridiculous internal spring tension holding it in place; so strong that to flush you have to pull the flush lever firmly or leave the top of the tank open so you can open the valve with both hands as if you were a competitor. Click your luck. Aside from the added difficulty of rinsing, it gets the job done, but I'm writing this as I've placed an order for a Sloan brand part. Just take a look.
