I keep at least one diaphragm on hand along with a back up Aqua Lifter.
I change them out about every 6 to 8 months and they never fail to work.
Make sure to use the filter for the pump its worth every penny..
Easier than Cleaning By Jack on 7/31/13

While you can pull the diaphragm apart from the check valve assembly and clean it out, it is a huge pain in the butt. For $2.50, it is much easier to just pull the entire assembly out and replace it. There are only a few screws to take out and this simply pops right in to either side of the pump.
great not to throw a pump away By Ryan on 1/7/13

My pump started to slow down quite a bit then stopped pumping water all together. I opened it up and attempted to clean it out but that didn't do much. I ordered one of these and the pump is brand new again. couldn't hurt to do this once every year or so.
