Have you had a look at the silicone rubber seal in the underside of the pump to see if it is misaligned, it will only go in correctly one way, the seal has got two indents which should locate with two pegs in the green plastic part of the pump, if fitted correctly the hole in the seal should align with the hole in the green plastic part, if misaligned the pump will not work correctly.
So yeah ... my Phallosan is utterly useless now. It no longer holds suction ... at all. Tried the recommendation about pumping against the hand ... also tried it against my thigh ... it does absolutely nothing. Not even the slightest hint that suction has taken place. It'll only hold the glans in place for about 10 seconds before coming out of the bell. I need a replacement bell/pump. This is incredibly frustrating.
