Anybody know how to do this?
I need to take a look under the faceplate because I suspect a problem. When the pump is on the faceplate is moving a bit, and I'm hearing hissing, like air escaping. And apparently there is air coming from where the little plastic doohickey attached between the prongs for the tubing - I stop hearing the noise when I plug it with my finger and it seems suction gets a little stronger. I suspect the diaphragm underneath might be damaged but not sure how to get in there. Is there a trick to it or do you just pry it off?
