Why did you choose this?
this doesnt look like the diaphram i pulled out?
BEST ANSWER: Is the only difference that your diaphragm has a brass plate on it? If so you just take that brass plate off and put it on the new one.
My diaphragm is 3 1/4" across is this one the right size, it really looks like it?
