New pool owner here trying to find some help with pool problems.
The other day I noticed that the pressure gauge on the DE filter was zero. Other than that everything seemed to be working fine. Had good suction on the skimmers and good pressure on the returns. I removed the filter basket and there were no obstructions to the pump. I could not remove the pump from the housing to check for debris because the installers put conduit right up against the pack of the pump . I also drained the DE tank and took off the cover. The DE screens are dark gray. Does this mean we need to backwash and then clean the DE filters? I called a local pool shop and they said it could just be a bad gauge.
Yesterday, when putting the system into Spa mode, the returns turn on for the spa but there is no suction in the spa skimmer. This caused the spa to overflow. What could cause this and is there anything I can do to fix it on my own? I'm thinking an obstruction somewhere in the line but don't know how to address it.
Could the problem with the pressure on the DE filter be related to the lack of suction in the spa skimmer?
Thanks for any help.
