It seems my sump under the stand is leaking; at least I hope its that and not DT. I noticed water on the floor this morning and checked, everything looked good except the tank was very full while sump was low. I adjusted the float as it seemed stuck and went on my way. Shortly after I hear the ATO pump making noise; so I check and no water. Hey wait a second I put water in last night. So I shut everything down do a quick wet vac. The rug is still getting wet all around the stand. The fact that I added to the ATO less than 24 hours ago and no water left, no leaks visible from DT and wet rug leads me to believe its the sump. I drained as much water from the sump I could leaving about an inch. Tonight I plan to pull the center stand brace and hope to get the sump out. I will put the brace back after. Any thoughts on any of this?
