Water pump problem
The pump is pretty durable, but it may be partially clogged and/or
need a rebuild causing it to overheat. That might cause a circuit breaker to trip then reset. (Don't know where they are on your year.) I'd guess that the expansion tank would need about 40# as that's what the operating pressure is ... but it may be lower. The pressure in the tank allows the pump to run at a constant speed until the pressure in the system is "right". Then the tank provides the pressure until it drops to the point where the pump kicks on again. If the water pressure at a faucet isn't significantly changing as the pump cycles on-off-on, then the problem may not be the expansion tank at all. If the pump needs a rebuild, kits are available for a modest cost $20~30 or so. Most often, the pump will 'seep' at the joint in the case between the motor and the pump section if it needs a rebuild -- but perhaps not. If you find the circuit breakers, swap the one for the pump circuit for another one with a similar rating. It could be a faulty breaker instead of the pump, but that's not as likely. Even if it is the breaker tripping, you'll need to determine why the breaker trips. Pete Masterson aeonix1@...
