Our well pump switch works fine, kicking in at about 30 psi. As soon as the switch turns on, the water pressure immediately drops off the scale and stays down for about 10 seconds. At that point, the water pressure goes back up to normal.
Could a check valve between the pump and the accumulator cause any problems?
I'm not convinced it's just the pump taking too long to get water pressure up, because when the gauge at the bottom of the picture reaches 30(ish, from memory), the pump switch switches on, and the gauge immediately drops to zero. (Faucets or anything else looses all pressure, too) The pressure just before this drops steadily.
UPDATE: So I tried checking the pressure. I turned off the house valve (green ball valve), turned off the pump power, and drained the water using the spigot until it gurgled (no longer dropping pressure and now putting air into the pipes). The tank pressure at that point read 45psi. The pressure switch is set for 40-60, and the card that is barely visible on the top right of the blue tank says the tank pressure should be 38 for that setup. I dropped the pressure down to 38, but I'm not sure that helped.
