Gotta another question (I know, surprise surprise LOL)
When I got my Sand Filter (in signature below) installed in December 2011 I noticed they plugged the opening where the pressure gauge went and when I asked they told me they have so many issues with them, usually leaking or breaking after winter season, they just stopped installing them but I could come by and pick it up if I wanted it and install it myself. I asked how do I tell when I need to backwash and he said to just do it every 2 to 3 weeks.
So after learning the ways of BBB and TFP I didn't know if I should get a pressure gauge, which size and if I just unscrew the plug and screw in the gauge and if I use plumber's tape? I think they used silicone to seal around the plug.
My previous filter had one, not same type, and I had it for more than one winter season and it never broke or leaked.
I have been backwashing every 2 or 3 weeks and it hasn't been real dirty while backwashing. Also I will be getting a screen pool cage installed in about 2 weeks so even less debris will exist so didn't know if I should even mess with getting one?
Thanks for the help and expertise and hope this is the right thread to post this in, if not apologies
