I'm finishing up my SLAM from earlier this week (my 3 y/o SWG cell went out without me noticing and pool turned green 
).
Anyway, I installed a new pressure gauge to my sand filter yesterday because the old one was rusted and not working. I have a VSP and rarely turn it on high.
When I installed the new gauge and turned the pump on high, the psi was flickering between 15/16. It never stayed steady (not sure if they're supposed to or not).
I added about 1.5 cups of DE to try to speed up the filtering and the psi never increased or stopped flickering. I let it run overnight and it was the same this morning, flickering with no increase. I went ahead and backwashed it and it still showed the same.
What does it mean if the gauge is flickering and there's no change? It does go to zero if I turn off the pump or turn it to low.
