    Low Pressure When Backwashing

    Welcome to TFP! I started a new Thread for your post. Please start a new Thread whenever you have a question or new topic as opposed to posting your question on someone else's Thread (we call that practice "hijacking"). Plus, posting your question in a new Thread is more likely to get responses and gives your question the attention it deserves. --BoDarville, TFP Moderator

    When I backwash, the flow of water has drastically reduced. Also, the sight glass has an air bubble in it. I am new to this pool stuff too and don't even know where to start on what to check.

    Welcome to TFP. I'm not sure what is going on but I'm sure someone does!
    I'd bet you my bikini you'll never get TFP water from a pool store!
