How often do you have to change the ozone generator filter/cartridge? thanks

[@goosecouple]

Will the heater heats up should the ozone injector malfunctioned?

[@superwhuffo1]

How many loops should there be ? One or two?

[@superwhuffo1]

Can you use a good blow dryer as a heat gun?

[@Prima10ne]

I dont understand. How can there be only 1 tube in/out? How does the water flow? Shouldnt there be 2 tubes (one in and one out)? How does the water move in this setup?

[@superwhuffo1]

When no air bubbles are coming out of the drain.
