I actually talked to him in detail about this very issue & he said you do more damage to the pump taking a shower or washing your car in the driveway. because the volume of water being used is higher & will empty the pressure tank faster causing the pump to turn back on in a shorter time. The rodi unit is using water much slower & the pump has plenty of time to cool, he told me it wasn't a issue.What do you mean I cycles instead of run time? Like the number of times it turns on?
