i was taking a shower today and lost all pressure in my system. I noticed the water filter was really clogged so I changed out the filter and turned back on the water instantly it filled up with sediment again. After work I connected a hose to the line just past the pressure tank. I turned off the breaker and ran the water until the system was empty I turned back on the breaker and did this a few times. A lot of sediment got flushed out. But all of sudden the pump just stopped. So I turned off the breaker and checked it a few more times. The pump would run for a while (clear water from what I can tell) and then all of sudden I would hear a faint click and no water like someone turned off a valve. It wasn't the pressure switch I checked this and the contacts were still connected. My pressure gauge doesn't work so I put one one the hose and watched it. After awhile the gauge would all of sudden start going up. It also seemed like the house lights would dim a little when this happened. What do you think is causing this to happen? What else can I do for tests before I call a well guy out to look at it.
