Hi all, new member and new pool owner. Just reading through Pool School and all of the other content here so thanks for all of the useful information.
My current problem is that when I first bought the home/pool the home/pool inspector noticed that the filter pressure gauge was reading zero and he told me that the gauge probably just needed to be replaced. My filter is a S8M150 (see signature line for other pool details). So I initially cleaned the main cartridge filters (2), pump baskets, skimmer, etc. I put it all back together and still got a zero pressure reading. I subsequently bought a new pressure gauge (gauge only, not the entire housing):

After I replaced with the new gauge I am still getting a zero pressure reading. I didn't follow any specific protocol when replacing with the new gauge, i.e. I basically just unscrewed the pump baskets a bit so air started to come out and depressurize the system while at the same time unscrewing the air/pressure cap on top of the filter to let some more air out until it was completely dpressurized. I then removed old gauge, put some latex tape on the fitting and screwed the new gauge on, then turned the pumps back on.
Do I need to replace the entire housing for the pressure gauge/air release thing on the top of the filter or did I re-pressurize the system in the wrong way? Since then I've been running the pumps, pool cleaner Polaris vacuum, etc. and haven't noticed any issues except that whenever the pumps turn on a small bit of water drips/leaks out of the filter (middle brackets area), but stops after the 1-2 seconds from the pumps initially turning on.
