For houses that have their own water supply from a well
If your water pump is coming on and shutting off and then coming on again in less than 10-15 seconds, it usually means there is insufficient air pressure in the cold water tank.
If left uncorrected, the system will use more electricity and shorten the life of the water pump and pressure switch.
Have a plumber add more air to the tank or, if the tank’s bladder has failed, the tank will need to be replaced.
