It's recommended to change jet heads every 6 months, but there are other ways to use the Waterpik Increase water flow and also extend the life of your Waterpik. If the water is hard, you should first clean the device with vinegar, if necessary according to the Waterpik instructions, and replace the seal on the water tank after about a year of use. You will be surprised how much this improves the water flow in the Waterpik. I really like the Classic Jet nozzle but they also make a low pressure nozzle that is good for sensitive gums.
