At 4am I heard the Racoons making noise and found 4 of them swimming in the pool.
They ran when I confronted them.
Can be a problem if they defecate in the pool.
Going to set up my small temporary electric fence near the pool steps.
Also installing the pool solar cover maybe that will ruin their pool party.
I turned on the pool solar heating last week, the racoons must of liked the 75 degree water.

So good news.

It appears the issue was a check valve at the equipment area.

The flapper had some excess PVC sealant on it so was not closing completely allowing the pool to siphon out the jacuzzi.

Basically a vacuum leak.

5 minute fix.
