Hi all, I have a Nautilus FNS DE filter and have developed a small leak from the bottom of the filter. I can't see where the leak is coming from but the slab under the plastic base and the dirt for a few inches around the base are damp. I noticed this after I experienced a spike in pressure a couple days ago. Normal pressure for my system is 10psi with 15psi being my target backwash pressure. Something caused a spike the other day to about 24psi and I believe this may have contributed to the leak.
Is anyone familiar with the workings of this filter system to help me identify potential failure points at the bottom of the tank ? There is a pipe that runs under the tank and connects to the backwash valve so I assume there are connectors that may have o rings that could have been damaged by the pressure spike.
I plan to do my annual cleaning of the grids in a couple weeks and figured that would be the best time to pull the tank and fix the leak so any advice on what to look for or a rebuild kit for the connectors would be appreciated.
