Got a Sloan flush valve that's acting up – either won't flush or keeps running?

Chances are the diaphragm is worn out.

This replacement diaphragm assembly is made for Sloan Regal models – it's the A38A / 5P213 rubber part that does the hard work of sealing the valve after each flush.

Over time, these rubber discs get warped, cracked, or just tired, and then you get leaks or weak flushes.

Swapping in this new one restores proper pressure regulation and a tight seal, so your toilet works like new again.

It's a simple fix that saves you from calling a plumber.

Fits Sloan brand specifically, so double-check your model.

If you've got a Regal valve, this is exactly what you need to stop that annoying running water.
