747. Will your bathtub heaters work on soaking tubs that do not have jets?

Yes, our bath tub heaters will work on soaking tubs that do not have jets. NOTE FOR SOAKING TUBS (with NO Jets): Soaking tubs normally don't have jets installed, and the output pipe is an open flow with minimal pressure. If a bath heater with built-in pressure switch is installed on a tub without jets, make sure to install a ball valve on the output side of the heater. Then adjust the ball valve slightly to the position that will allow the heater ON light to turn on (water temp must be below 104 degrees). This is to increase water pressure in the pipe that will activate the pressure switch on the bathtub heater. Do not adjust the ball valve completely. This will stop water flow and can damage the pump and bath heater.
