The air blower for my spa stopped working, so I need to replace it. Can anyone give me a recommendation? I was thinking about the Polaris 1-480-02, which is 2 HP. This model is plastic, but I noticed that there is also a metal version. Would one of these be a good choice, or should I look at something else?
My existing one is only 1.5 HP. Will I have any issues upgrading to a more powerful unit?
