When it rains it pours. I've just started my SLAM and now I have noticed that the pressure gauge on my Hayward filter isn't working. Also noticed when I backwash that the little sight jar is only half full of water and doesn't seem to move around any. I'm getting a film of algae on the bottom of the glass that doesn't move.
It all sounds ok when running, but I'm wondering how easy it is to fix/replace those things.
I was wondering if perhaps the gauge could just be cleaned. There appears to be some salt creep around the base from a leak at the top of the filter last winter.
