Drained the tank. Inside under tank rear left corner is dry. This is puzzling. Any idea?
Next step is to raise the tank, insert 2x4 under and fill 10-12" of water. Then observe.
Fudd. Got a leak rear left side of tank. The wood is wet and i dried it 5 minutes ago. Time to drain. Urgh. Good thing the water will be used for the above ground pool
It was a peninsula tank. I removed the internal overflow in an attempt to convert it to a sump. Leak test passed.
But change of plan. Don't need it.
