i have been having inconsistant water pressure (actually only getting water for about 20 minutes then lose it for about 4 hours)its regular enough that you could almost set your clock by it, i replaced the switch about 2 weeks ago. seemed to work right away but within hours , back to the same problem. when the water comes on its powerful, but after 20 minutes or so it is a trickle i checked the bladder tank today and it seems to be completely full of water. when i replaced the switch it had very little in it, did i blow the bladder tank when i replaced the switch, i found that the guage was faulty and have no idea what pressure the switch is set at. any help would be appreciated very much. thanks, mike
