If I leave the pump on in my tub so it can heat will it burn up since it needs to be on to heat. And how long do they usually run? Do I need a timer since I by passed and have plugs for the heater and pump?
Most jet pumps will shut off after a period of time or if they become too hot. Usually a jet pump will run for two hours and shut off. If properly done your jet pump will be a two speed pump and run on slow speed for heat cycles and automatically shut off when the hot tub reaches the set temperature. Both your heater and pump need to be wired in conjunction to the thermostat relay to make sure that occurs.
