Title: It works
Review: After a year or two the Korky valve starts to pulse when it shuts off. Cleaning the diaphragm buys a little time, but the only cure is to replace the diaphragm. This completely fixes the problem and is far easier than replacing the whole valve. This was an economical place to purchase it since they didn't overcharge for postage. To save further, I purchased two diaphragms at once.
