You can also purchase rebuild kits versus new. Be sure to check that the bleeder hole in the membrane is not clooged before ordering a replacement. There is suppose to be a very tiny hole in the membrane, and when it clogs, the valve will not close properly. BUT, and that's a big 'butt', make sure you put the bleeder hole in the same postion as where you found it.
