I have a Jandy CL340 cartridge filter, and its pressure gauge has been reading zero. I figured it died, so when I last cleaned the filter, I replaced it with a new OEM gauge: Amazon.com: Zodiac R0357200 Air Gauge Release Valve Assembly Replacement for Select Zodiac Pool and Spa Filters: Garden & Outdoor
The new one reads zero as well. I don't think there's anything blocking it, as its relief valve works and water squirts out of it when opened. Anyone have an idea as to what's going on?
