That many human noises coming from the tank sounds like it would make a funny utube video. If the pressure drops as soon as the pump shuts off, the check valve on the pump is probably bad. Tanks don’t usually make noise unless water is entering or leaving the tank. A bad check valve could cause the pump to cycle on and off enough to destroy the bladder in the tank. If the noise you hear is the bladder rubbing the tank, it won’t last much longer.
