..............The heat in the checkvalve is probably being transferred from the pump motor via the metal to metal contact. The chkvalve has a spring that the pressure from the pump motor has to overcome and then the water flows around it (on the NSIDE of the chkvalve) , as long as the motor is running. IF, the chkvalve ISN'T opening correctly it will prevent the water from reaching your pressure tank. Normally, if the motor is having to work too hard the Breaker should pop to keep from burning up the motor. If, you UN screw the checkvalve i would take it to your local hardware store and Buy a replacement. Besure and buy Teflon tape and Wrap each end when you screw it back into the line. You may want to also check your pressure tank. IF , you have the old style pressure tank which has the air bubble in the top , you MAY have a shutoff valve on the tank, IF SO, Turn it off ,,,,,,,BEFORE....removing the chkvalve and you maybe able to retain your air bubble in the top. TURN OFF POWER too the pump before letting anyone work on it for you.
