First thing to do is remove it and hook a hose to it submerge it in H2o and either blow or suck or both and see if it has any leaks.

Next with the valve removed from the H2o suck on the hose and and let go the diaphram should return to the closed postition slow and smothly without any sticking if all this is good then you need to look at the vaccum connections fittings lines if there good then look at the Ele. connector on the vaccum solinoid for any corrosion or any other defects. if it looks good then it may be the solinoid but you should test it befor you replace it.
