I just replaced my broken pressure gauge and it stays at 0.
I put on the new one, bled it until all the air left and a stream of water came. I put Teflon on the gauge and tightened it when a wrench.
I can see flow being pulled in to the skimmer.
My pump basket has a see through lid and I can see water moving turbulently in there with some debris.
There is a strong flow of water thru the return back to the pool.
The filter has an intact O ring (if that matters)
I just cleaned out the grids, turned on the pump and got a reading of 0 (I haven't put the DE in). Is it at 0 because there's no DE? I haven't put in the DE because I want to know the system and the gauge are fine so I can get a baseline/start reading when I put in the fresh DE.
